Can the drum unit be cleaned with alcohol. How to clean a laser printer. Important points before cleaning

Photo drum (photo drum) - the inner part of the laser cartridge, which is used to print. The drum unit has a service life of over 10,000 pages. However, due to low-quality toner, high humidity in the room or temperature changes, the photo roll may start printing pages with defects: gray background, stripes, blots, dots.

Most of the above problems can be solved by cleaning the drum unit. It is produced in service center MiraxPrint and is included in the cost of refilling cartridges. Thus, we provide an opportunity for our clients not only for printing, but also for servicing office equipment!

However, those users who are used to doing everything with their own hands can familiarize themselves with the recommendations from the specialists of the MiraxPrint SC in order to clean the drum qualitatively, while avoiding damage to the expensive part.

Important! Cleaning the camera yourself may cause damage. In this case, you assume full responsibility for the performance of the part.

DIY drum cleaner

Before we start cleaning the drum, let's talk about chemicals. Many specialized fluids are sold on the Internet, designed to take care of the photogallery, but you should not waste your money. It is enough to wipe the body of the part with microfiber or universal cleaning wipes, which does not leave lint behind.

Note!Do not use any products that contain alcohol, ammonia, or solvents to clean the drum unit. This will damage the sensitive surface of the part, which is not even recommended to touch, except for cleaning purposes.

DIY step-by-step instructions for cleaning the drum unit

STEP # 1: Turn off the printer. Unplug the power cord from the outlet. Wait about 5 minutes for the printing device to cool down.

STEP # 2:Open the front cover by yourself or with a button. It all depends on design features apparatus.

STEP # 3:Remove the cartridge.

STEP # 4:Slide the protective shutter of the cartridge by unscrewing the corresponding screws. A green or blue drum will be hidden under the shutter. Wipe it down with a microfiber or all-purpose wipe. Hold the photo roll by the ends without touching the coating. Otherwise, the remaining traces will be visible on the printed documents.

STEP # 5: Collect the cartridge and put it back in the printer.

On a note! By default, the drum is cleaned with a special blade called a squeegee. As it wears out, the gap between the blade and the drum increases, leading to permanent printing problems. Therefore, in the process of cleaning, be sure to check the integrity of the squeegee design, as well as the level of the gap - it should be the same along the entire line of contact with the photo roll.

The printer has stopped printing well? The primary cause is a clogged cartridge. Let's figure out how to clean a printer cartridge. First you need to define the printers themselves. Printing of documents, photographs and other graphics is done using printers. They are of several types:

• jet;
• laser;
• matrix.

They differ in printing methods, speed and field of application.

Inkjet printers use dot matrix heads that print the image in dots. A distinctive feature is the costly maintenance of the printer. Since inkjet machines have a fairly high ink consumption, they are mainly used for home printing in small volumes. However, there are many types of inkjet printers. They are divided according to the type of ink and purpose. Here is some of them:

• office;
• interior - used for printing interior design;
• large format - used for printing advertising banners and other advertising inventory;
• marking - for applying symbols on products, parts;
• photo printers;
• souvenir - used for printing on various kinds of souvenirs.

Laser printers

Without going into technological details, we can say that when printing, a drum is used, which outputs a dotted image. In terms of basic parameters, an inkjet printer is inferior to a laser one.

Have a laser printer high quality printing on any paper, lower maintenance costs, faster printing speed. Of the minuses, only a higher cost can be distinguished. But if you take into account that the maintenance of a laser printer is much cheaper, then this minus is compensated for.

Print cartridge

This special ink-filled device is used as a medium for supplying ink to the printing device of the printer. The print quality of the image directly depends on it.

Provided the cartridge is clogged, the color rendition will deteriorate and overall quality printing, individual colors may not be printed.

Difference between inkjet and laser printer cartridges

The laser printer cartridge is filled with toner - a powder made of dye and wax or the like.

Under the influence of high temperatures, the heated powder is applied to the surface of the paper. An inkjet printer uses liquid ink to print.

How to clean the cartridge

The main thing is to remember that when you self-clean the cartridge from dirt, other components of the printer may become unusable. This will greatly increase the period and cost of restoring the cartridge at the service center. Cleaning the cartridge is not the easiest and safest procedure for both you and the printer. If possible, it is best to purchase a new cartridge.

How do I clean a laser printer cartridge? The powder used to fill the printer cartridge is hazardous to health. Proven: getting into Airways, toner can cause about a dozen different diseases. Therefore, when cleaning the cartridge yourself, do not open windows and doors to prevent the toner from flying apart. Wear respiratory protection. First of all, it is worth trying to use the software utility of the printer itself. It provides the ability to clean the printer cartridge. If that doesn't work, then there are several ways to clean up.

Chemical soaking. If you decide to do self-cleaning, then first remove the cartridge from the printer. Then take a container with a lid, pour 1 cm of glass cleaner into it and dip the cartridge into the liquid. Provided that it has not been used for a long time, dilute the liquid with water in a one-to-one ratio. Close the container tightly with a lid and leave for 12 hours. The cleaning indicator will be the darkened liquid inside the container. After the cleaning period, remove the cartridge from the container and check. Attach the print part of the cartridge to the paper: if a clear, blur-free, black print (for a black cartridge) and blue, red, yellow prints (for a multi-colored cartridge) is printed, then the cartridge is cleaned.

Hot evaporation. Probably the easiest method to clean the cartridge. This method does not require special equipment and a long period time. Take out the cartridge. Boil water until steam appears. Hold the cartridge over hot steam for about 5 seconds. Then, as with chemical soaking, the cartridge is checked by the printable side on the paper. If the paper produces poor-quality prints, the procedure must be repeated. Although the method is simple, it can have Negative consequences... If the cartridge is overexposed over steam, there is a great risk of peeling parts.

Washing with a special clip. Most effective method cleaning, but also the most expensive, since you need to purchase a special clip for cleaning. First, the cartridge is filled with window cleaner and water in a one-to-one ratio. Then the mixture of water, liquid for cleaning glass and ink is sucked out of the cartridge with a special clip. After sucking out the remaining ink, check the print quality in the same way as in other methods.

How to clean the “Samsung ML-1520” cartridge. You need to unscrew 5 screws, loosen the latches with a screwdriver or other flat object and disassemble the cartridge. Next, you need to unscrew three screws on both sides and remove the fasteners. Then - unscrew the two screws holding the drum unit and remove it. When you remove the drum unit, immediately put it away in a dark place. Next, you need to remove the magnetic roller and clean the inner contents of the cartridge. Cleaning is over, now we collect everything in reverse order, refill with toner and make a test print.

How to clean an inkjet printer cartridge

How to clean the cartridge inkjet printer“HP” and “Canon” inkjet printer cartridge. There are several ways to clean an inkjet printer cartridge. We will consider only the most effective ones.

Burying. The cartridge is removed from the printer and placed with the nozzle facing up. A small amount of cleaning agent should be applied to the nozzles. It can be a special cartridge cleaner or a regular window cleaner. In this position, the cartridge should stand for about 20 minutes. Then the surface of the cartridge is wiped with a dry cloth and checked during printing.

Air cleaning. For such cleaning, you will need a syringe with a needle. We draw air into the syringe, insert the needle into the hole for refueling, and then press the plunger. The ink should come out of the cartridge nozzle under air pressure.
Maceration. The cartridge is removed from the printer and immersed in distilled water or a special liquid to clean the cartridge. It is placed in the water in the same position as it was in the printer. Leave the cartridge in the liquid for a time from a couple of hours to a couple of days.

How to clean a dried HP cartridge and a dried Canon cartridge. When a cartridge that has been left without work for a long time dries up, special methods are used that are suitable only when the cartridge is dry. They are mainly associated with the influence of high temperatures. Evaporation is one such method.

Evaporation. We prepare a shallow container and boiling water. Pour boiling water into a container of 1 cm. Without waiting for the water to cool, dip the cartridge in boiling water in the position in which it is in the printer. We will dip for 30 seconds, no more. We repeat the procedure 3 times. In this case, the cartridge must be refilled. Then we remove the cartridge from the liquid, dry it with napkins, immediately place it in the printer and produce several test prints at the highest quality.

How to clean the printer drum

Another reason for poor print quality may be a clogged drum unit. Unplug the printer, remove all cables, remove the toner cartridge, and remove the drum unit. Poor sample place in front of the drum unit to pinpoint the exact location of the poor print. Once you have found a place, clean it with a dry cleaner: cotton wool, napkin, cloth. After cleaning, reassemble the cartridge and reinsert it into the printer.

Important! When cleaning the drum unit, do not touch it with your fingers or sharp objects. The surface of the drum unit is sensitive to damage.

How to refill the cartridge

After any cleaning of the cartridge, the cartridge must be refilled. The simplest solution would be to take the cartridge for refueling. If you want to refill the cartridge yourself, do not forget that this is not an easy procedure. By the way, the manufacturers of cartridges themselves do not produce means for refilling them. Inkjet and laser cartridges are refilled different ways.

How to refill an inkjet cartridge. Get quality paint first. Poor quality paint will cause the cartridge to dry out and repeat the cleaning procedure. Take an ordinary syringe and fill it with paint. There is a small hole on the surface of the cartridge, often covered with a sticker. Peel it off without breaking the integrity, and pour the contents of the syringe into the cartridge. Then stick the sticker in place - if you don't close the hole, the paint will simply spill out.

How to refill a laser printer cartridge. It is worth recalling that the powder used in laser printers is hazardous to health, and the laser printer cartridge should be refilled in an unventilated area using respiratory protection.

• If you are not sure of your capabilities, then it is better to take the cartridge to a special service center.
• The first step is to purchase a special powder used as paint. Then cover the surface on which you will refill the cartridge with film or paper to prevent powder from falling on the table or carpet.
• There are models of cartridges with a special lid behind the side mount. Powder should be poured under this cap, and the filling is completed. In the absence of a cover, complete disassembly of the cartridge is required.

Although in words, cleaning and refilling the cartridge are simple procedures, their implementation takes a long time, and in some cases, special equipment. Therefore, the most correct and safe solution would be to take the cartridge to a service center for refueling. Frequent printing and timely refills are essential to keep the ink inside the cartridge from drying out. Some cartridges may simply not be able to be cleaned due to complete drying. In this case, it is much easier to purchase a new cartridge than to torture the old one.

The most important stage of work when refueling and restoring cartridges of laser printers is cleaning laser printer cartridges from old toner and various other contaminants.

The print quality of a refilled remanufactured cartridge largely depends on how thoroughly and in compliance with the technologies the cleaning procedure was carried out. Much depends on the tool used during the work, auxiliary equipment and materials.

Today, there are hundreds of a wide variety of cleaning agents, the manufacturers of which promise to increase efficiency when restoring and refilling laser printer cartridges, increasing the service life of the components that all these agents are designed to clean, but in practice, the best results are provided by using only dry ionized filtered compressed air, which can be considered the main cleaning agent. The less you actively influence the components of the cartridges, the better, since in this case their useful properties are not subject to all sorts of undesirable changes. A cartridge is a complex system of interconnected components, therefore it is very important to maintain the initial balance of the entire system and the properties of its individual components for as long as possible. Rough and flawed cleaning the laser printer cartridge usually has the opposite effect and negatively affects the quality of the functioning of the entire system. Effective cleaning should ensure that breakdowns are prevented and that an optimal balance of the entire system is maintained. Cleaning with dry ionized filtered compressed air is recommended for all types of cartridges, because it has no chemical or mechanical effect on the components of the cartridge, if, of course, cleaning is carried out correctly. Cleaning agents can accumulate or leave sediment, which is also harmful for the cartridge and its components (for example, the use of various types of solvents for cleaning the squeegees: chemicals can leave a film on the squeegee, which can subsequently get onto the photoreceptor and the primary charge shaft) ... Therefore, the use of various cleaning, impregnating and coating agents in this kind of work is prohibited. Alcohol-based cleaning agents will damage the drum surface, magnetic shaft a, cleaning and metering squeegee, as well as the surfaces of some types of primary charge rollers. The components of the cartridge, having a direct relationship to the overall imaging process, can affect the quality of the print. Thus, changes in the surface properties of individual components due to chemical or mechanical stress, as a rule, significantly degrade the quality of subsequent printing.

Cleaning methods for laser printer cartridges

Compressed air- the most efficient and effective method of cleaning all components of the cartridge. Due to the fact that you cover a larger area with the cleaning head than when cleaning with a vacuum cleaner (during vacuum cleaning), it takes a minimum of time to complete the cleaning process (in addition, it is possible to direct air into narrow holes, which is impossible with vacuum cleaning). Fragile parts and materials used in cartridges, such as foam and felt, are difficult to clean without causing damage. The compressed air used has special requirements: the oil and water contained in the air streams can be transferred to the cartridge parts, which can significantly increase the likelihood of printing problems. Static electricity can cause dust and toner to adhere to the surface of the cartridge, from where they travel from one part to another contaminate the entire cartridge, making it extremely difficult to remove the toner and dust. But using dry ionized compressed air coupled with suitable system cleaning from dust, you can significantly increase the efficiency and quality of the cleaning process (in this case, it is necessary to use the appropriate nozzles and protective equipment).

Isopropyl alcohol when cleaning cartridges can be both useful and harmful. Alcohol can be considered harmless for the electrical contacts and the saddle contact of the primary charge shaft - PCR. But alcohol can damage: magnetic roller, imaging drum, PCR shaft, polyurethane and silicone, from which the dispensing and cleaning squeegee is made. For best results, only 91-99% isopropyl alcohol should be used. Alcohol with a high water content, takes much longer to spray and leaves the surface wet for a long time. Every time you use alcohol, you must make sure that the surface of the cartridge parts is dry, and this must be done before filling toner and reassembling the cartridge.

Vacuum cleaner is an alternative to dry ionized compressed air. It is necessary to use special brush attachments and special attachments for cleaning narrow crevices when cleaning. During cleaning, avoid touching the nozzles to the drum surface, magnetic roller and PCR. But the vacuum cleaner has a significant drawback - when using it, it is easy to damage the fragile and sensitive components of the cartridge, various seals and gaskets, the film of the return squeegee, you can tear off and push out pieces of felt seals. In addition, the electrical contacts on the cartridge could be damaged. By applying too much pressure to the nozzle of the vacuum cleaner while cleaning the toner hopper through the hopper, you can easily bend the toner sensor rod or the axis of the toner stirring paddles. If the rod (antenna) of the toner sensor is bent away from the magnetic roller, this will produce a premature display of the toner low message.

Lint-free cloths and brushes, soft, lint-free wipes and cotton lint-free brushes great for cleaning cartridge components. The so-called toner wipes are saturated with mineral oil, which can contaminate the cartridge components and should not be used to clean the inside of the cartridge. To avoid the absorption of chemical cleaners, oil and cotton fibers into the cartridge components, use only dry, cotton-free cloth (toner wipes are only used to clean the outside of the fully assembled cartridge). Lint-free materials are very good for cleaning with alcohol or for applying a conductive lubricant, but should not be reused afterwards.

Lubricating powders such as "KYNAR "(domestic experts call them "talc for a photodrum") are produced by various manufacturers, but one of the most famous is the lubricating powder "KYNAR" (this is a fluorinated polymer). By treating (sprinkling) the new drum unit and new wiper blade with lubricating powder before placing them in the cartridge, you reduce friction between them during the first rotations. Under no circumstances should the lubricating powder be allowed to come into contact with the PCR. this may cause defects in the printed image. Even a small dot of the lubricating powder on the PCR surface will cause the “repeating black dots” defect.

When refilling a cartridge, make sure all electrical contacts are free of dirt and toner. Dirt on the cartridge contacts can cause poor charging of the magnetic roller and drum unit. It is best to clean the contacts with 91-99% isopropyl alcohol and a lint-free cloth. Then apply a thin layer of conductive grease to the places where it was originally applied by the manufacturer.

Conductive grease used in most cartridges to reduce friction at electrical contact points. The lubricant application for each cartridge is different. For detailed information on the use of conductive grease, you must use the instructions for refilling cartridges, which are sometimes issued by manufacturers of compatible Supplies... When refilling the cartridge, remove the old lubricant with a cotton-free brush or cloth. Only then should the new lubricant be applied to the same surface. It must be applied very carefully. The lubricant should be applied in a thin layer, the thickness of which is comparable to the thickness of a sheet of a notebook.

Cleaning cartridges: tools and equipment, procedure, little tricks

There are hundreds of products on the market dedicated to cleaning and restoring cartridges. They all promise to improve their productivity, restore appearance and even increase the durability resource. However, over the years, employees of the research laboratories of Static Control Components have made sure that the most effective were and remain the old proven methods of cleaning: dry, ionized, filtered compressed air, a service vacuum cleaner, lint-free wipes, cotton swabs, isopropyl alcohol and Kynar talc.

Cleaning practice also shows that the less you affect the properties of the components, the better. The cartridge is a complex system of interconnected elements, and it is very important, as far as possible, to maintain its original balance and characteristics that affect the formation of the image. Damage from handling or the use of harsh cleaning agents, even of one component, can negatively affect the functioning of the entire system. Therefore, the primary goal of effective cartridge cleaning is to prevent such damage and to keep the system balanced.

Cleaning with dry, ionized, filtered compressed air is recommended for all cartridges, since this method does not affect the components either chemically or structurally (if done correctly). Cleaning agents can cause the formation of chemical build-up or leave streaks that harm both individual parts of the cartridge and the entire system as a whole. An example of this is the use of squeegee cleaning fluids. Some chemicals form a film on the blade, which is then transferred to both the drum unit and the primary charge roller.

Be careful when using a variety of cleaners, restorers, and coatings. For example, the use of alcohol-based fluids adversely affects the drum unit, squeegee, leveling knife, magnetic roller and certain types of primary charge rollers. The surface properties of the components are very important for the image reproduction process, and changing at least one property will affect the operation of the entire system as a whole.

Dry, ionized, filtered compressed air

Compressed air is the most effective method for cleaning cartridge components. It takes little time because with the air tube you can cover a large area at once and direct the air flow into small holes and narrow slots, which is not possible with a vacuum cleaner. Fragile materials (foam rubber, felt) are easily and thoroughly cleaned without any damage to their structure.

However, compressed air alone is not enough. Oil and water can enter the cartridge components and greatly increase the likelihood of printing problems. Static electricity causes dust and toner to accumulate on the surface of the cartridge, where it simply moves from one place to another and is not easily removed. The use of dry, ionized, filtered compressed air and dust control systems can significantly improve cleaning performance. When working with compressed air, use suitable nozzles to ensure the safety of the work.

Isopropyl alcohol

Using rubbing alcohol in the cleaning process is both good and bad. Alcohol is not harmful to the electrical contacts or primary charge roller seats, but is harmful to the magnetic roller, imaging drum, some types of primary charge rollers, and polyurethane and silicone on the squeegee and leveling blade. Never use it to clean or handle these components.

You should also avoid getting alcohol on foam rubber or felt - this can damage the adhesive backing, the material will not adhere well to the cartridge, which will lead to toner leaks and printing defects.

For best results, use only 91 to 99% isopropyl alcohol. Alcohol with a higher water content will take longer to evaporate or the surface will remain damp at all. Whenever you use alcohol for cleaning, make sure that the surfaces of the components and the cartridge are completely dry before refilling the toner and collecting the cartridge. 99% isopropyl alcohol is available from virtually all chemical distributors, and 91% isopropyl alcohol is readily available in most pharmacies.

Printing defects

Black-on-black print defects are large black dots and wide black horizontal lines that repeat at drum spacing in printouts with a black solid (fill) pattern. These dots and lines represent a build-up of excess toner in the developing areas. This defect is the result of cleaning the cartridge with compressed air at high speed. The immediate cause of a black-on-black defect is the appearance of a high positive charge region on the drum surface. Typically, the drum unit receives this charge from a magnetic roller, leveling knife, squeegee, or primary charge roller. A high positive charge on these components is created when high-charged toner particles are removed from the non-conductive surfaces of the components (and the drum unit itself) by air blasting great strength... The additional charge is also caused by the friction of the air flow against the surface of the components. In an assembled cartridge, high positive charge components come into contact with the drum unit, and the positive charge flows to the drum surface, trapped in the conductive top layer. The drum used in laser printers is not able to evenly distribute the charge accumulated in a particular place. Therefore, the localized charge, remaining in the conductive layer of the drum, can disable it.

To prevent black-on-black defects, you must ground the components before installing them in the cartridge. However, grounding is not the ultimate solution to this problem; it does not remove particles from the surface of non-conductive materials.

Using the optimal air pressure and ionizer significantly reduces the excess charge on the cartridge components. The ionizer creates a constant flow of negative and positive ions, this flow neutralizes excess static charge on the surfaces of the components being cleaned.

Service vacuum cleaner

A service vacuum cleaner is an alternative to dry, ionized compressed air. When vacuuming, use a brush to clean the cartridge surface and a crevice tool to clean narrow holes. Avoid contact with the drum, magnetic roller, or primary charge roller.

Vacuuming can damage cartridge components such as the gaskets or drum cleaning blades, move felt or foam parts, and even break some electrical parts.

If you press down on the attachment slightly while cleaning the toner box through the toner fill hole, you can bend the toner level sensor and the tedder. The result will be a recurring untimely toner hopper warning alert.

Lint-free wipes and cotton swabs

To prevent chemicals, oils, or lint from getting on the inner parts of the cartridge, use lint-free wipes and cotton swabs, which are very easy to clean because they are made of a soft, non-abrasive material. They are also excellent applicators for alcohol or conductive lubricants.

The toner remover wipes are impregnated with mineral oil, which contaminates components, and cannot be used to clean internal components. They are needed to wipe the outside of an already assembled cartridge.

Talc Kynar

Kynar is a fluorinated polymer commonly used to lubricate the squeegee during cartridge assembly. Sprinkling the squeegee and imaging drum with Kynar talc before inserting them into the cartridge will reduce friction between the drum and blade during the first revolutions of the drum. Do not allow Kynar to build up on the primary shaft as this will cause print defects. Even a small Kynar particle can inhibit charge transfer to the drum unit and cause a repetitive black point defect.

Primary charge shaft

Clean a new, original or remanufactured primary charge roller with a lint-free cloth dampened with water. It is best not to use alcohol, as it can damage the surface of the shaft. The determining factor in the quality of the primary charge shaft is its design. Cleaning agents, waxes and reducing agent can give a shaft a shine and a great appearance, but they do not improve its performance in any way and, on the contrary, can damage the shaft itself and other components of the cartridge.

Drum

The drum should only be cleaned with dry, ionized, filtered compressed air, being careful not to touch the surface of the drum with your fingers. Store the drum unit away from light and other external influences before installing the drum unit in the cartridge. Cleaning fluids or cleaning agents for the drum coating do more than just have adverse impact on the drum itself, but they can damage the squeegee, primary charge roller and magnetic roller, so they should not be used.

Squeegee and leveling knife

The blade is less than 0.025 mm thick and any abrasive action (such as wiping with a tissue) can dull the blade and cause squeegee-dependent defects.

It is best not to treat the squeegee at all with any cleaning polishes or coatings: they will not increase its service life, but they can cause numerous problems, for example, formation of a film on the drum unit and primary charge roller, and poor drum cleaning. The use of creams, coatings or other squeegee treatments will result in build-up on the blade surface that cannot be removed with compressed air.

Alcohol belongs to the same cleaning category as creams, polishes and coatings. Tests have shown that polyurethane knives absorb alcohol and soften, and therefore, when rubbed, their working surface deteriorates. Alcohol absorbed into the polyurethane has a negative effect on the drum unit. It is not recommended to use alcohol on the squeegee or leveling knife, but to clean them only with dry, ionized, filtered compressed air.

Kynar talc can be used to lubricate the squeegee. Dip the working surface of the squeegee in lubricant (if using Kynar talcum powder). Install the drum and squeegee into the cartridge, rotate the drum several times in the direction of its normal working motion, or rotate it until talcum powder falls into the waste bin.

Using a conductive grease

A conductive lubricant is used in most cartridges to improve conductivity and reduce friction where electrical contacts make contact.

The general rule of thumb here is to only apply conductive grease where it was applied in the original cartridges, as their manufacturers always take this issue very seriously. However, since all cartridge systems are different, the lubrication patterns are also different from each other. Carefully read the instructions for restoring this particular cartridge before proceeding.

Whenever you replace a cartridge, wipe off the old grease with a swab or tissue before reapply. When replacing worn cartridge components, lubricate the new parts where the old ones were lubricated.

Moderation is a word to always remember when applying a conductive lubricant. We recommend a paper-thin layer. To do this, use the wooden end of a cotton swab. If applied correctly, it will work effectively throughout the cycle.

Although lubrication improves conductivity, it does not increase conductivity. Applying additional grease in the hope of increasing the charge on the magnetic roller or drum unit will not darken the print. Conversely, excessive amounts of it can spread throughout the cartridge, adversely affecting the performance of other components.

Magnetic shaft

The magnetic roller should be cleaned with dry, ionized, filtered compressed air. When doing this, hold the shaft by the axles or use rubber gloves. Touching the magnetic roller with your fingers will leave greasy stains on its surface, which can cause printing defects (for example, background or dirty stains on the print that repeat at intervals of the magnetic roller circumference). We do not recommend the use of chemical cleaning agents for the coatings as they will degrade the print quality. Various types of reducing agent often lead to thickening of printed characters, reduced productivity, problem with light printing, the appearance of a background, and can also increase the tendency for the formation of a film of toner additives on the surface of the magnetic roller.

Electrical contacts

Whenever you rebuild a cartridge, be sure all electrical contacts are free of toner and other debris, as these can negatively affect the consistency of all parts of the cartridge. Wipe the contacts of the magnetic roller and the primary charge roller, the socket of the primary charge roller with a cotton swab (or a lint-free cloth) moistened with 91-99% isopropyl alcohol solution. Then apply a thin layer of conductive grease to the contacts.

When it comes to how to clean the drum (photo drum), then in 99% of cases you will need microfiber or any other lint-free cloth.

You can also use compressed air cylinders or special cleaning agents based on isopropyl alcohol, such as Xerox Cleaning Fluid.

CAREFULLY! In no case should you resort to using ammonia or ethanol solutions, which can destroy the fragile photoconductive coating.

After cleaning, the drum unit must be reinserted into the toner cartridge.

If your cartridge has a waste ink bin, like on HP or Canon consumables, then lubricate the part with talcum powder. In its absence, it is sufficient to dispense with the used toner. Otherwise, the drum unit may jam against the squeegee.

Why is the imaging drum clogged?

In most cases, problems with the drum arise due to the use of low-quality paper in the printing process, from which microparticles literally spill out, clogging the internal elements of the printer.

It is also very common for the drum to get glue. Especially if users choose to economically print on used paper with reverse sides.

When do you need to replace the drum unit?

If you practice refilling cartridges, then the imaging drum will need special attention. Since this part is usually the first to fail.

You need to focus on the characteristic black stripes or spots along the edges of the print.

Have you recognized it? Cleaning the drum unit won't help - it's time to replace it!
