How to maintain the color photocopier drum?

During the use of the color photocopier drum will be gradually damaged due to friction with the scraper, the surface of the drum is repeatedly rubbed 3-4 times with a drum polishing cleaner, (do not let the surface of the drum leave a cleaner) and then put back the drum frame can be used, with this method can lubricate the drum, reduce the friction between the drum and the scraper, and prolong the service life of the drum.

The color photocopier drum will not be clear after some time of use, which is the photosensitive layer of the drum has been gradually damaged, and the repeated method is to use a photosensitive drum polishing cleaner to repeatedly rub the surface of the photosensitive drum 3-4 times (do not let the surface of the photosensitive drum leave a cleaner) and then put it back on the drum frame to use).

The following matters should be paid attention to when replacing the drum core and scraper: (1) The new OPC drum core is generally wrapped with black paper, and the label should be uncovered when taking the drum, and the drum should be taken out after opening the black paper, and the drum should not be pulled out directly from the black paper to avoid scratching the drum surface; (2) In the process of taking and loading the drum, handle it gently, do not touch foreign objects or directly touch the surface of the OPC drum with your hands; (3) When installing the drum core and scraper, apply an appropriate amount of toner on the scraper, and rotate the drum core in the correct direction for one week to help prevent scratches on the drum surface.

To keep the photocopier clean, the photosensitive drum should be wiped regularly with detergent, and a professional needs to disassemble it.

From a professional point of view, it is necessary to be maintained by professionals, and the user mainly pays attention to controlling the use time not too long, the amount is not too much, and the use environment is conditional to make a dust-free room.

1. Open the front cover of the Ricoh MP2000 copier, remove the powder supply holder and the powder bottle;

2. Open the door on the right side and pinch the plastic buckle under the drum unit, that is, remove the entire PCU unit;

3. Put the drum unit on the ground or desktop with the waste newspaper, disassemble one screw at the front end and two screws at the back end, as well as the front and rear end covers, and the upper and lower parts of the drum unit can be separated;

4. Flip the upper part onto the paper, remove the white buckle on the front end, and remove the photoreceptor drum. After cleaning the waste powder or impurities you see, you can put the new drum back.

However, it is recommended to clean the scraper and charging roller and replace the developer with the induction drum to ensure the quality of the print and the life of the induction drum.

Precautions: Do not touch the surface of the induction drum directly with your hands, you can take both ends of the induction drum.

1. After removing the photoreceptor drum, do the necessary cleaning work. The new drum should be loaded directly into the box holder after opening, and should be loaded into the machine as soon as possible. Do not place the drum in direct sunlight and do not allow its surface to touch hard objects.

2. Do not touch the surface of the drum with your hands or unclean items. When there is dust adherence, it can only be gently brushed off with a soft brush, not scrubbed with any detergent, and if necessary, it can be cleaned with toner.

3. For the photosensitive drum and toner are integrated mechanisms, they should be replaced in sets at the same time. Shake the toner well before loading.

4. When replacing, the toner that falls inside and outside the printer can be sucked off with a vacuum cleaner and scrubbed with anhydrous alcohol.

5. The replacement work should be carried out in a darker studio. In addition, it should be noted that the validity period of the photosensitive drum is two and a half years when it is dismantled at the end, and the validity period is six months after unpacking, and the expiration date is printed on the drum box.

Characteristics of drum damage.

1. Scratches. Caused by friction with surrounding parts during rotation, the shape is fine lines, and the fine black lines reflected on the copy paper are along the direction of paper feeding, with different lengths.

2. Bump marks. In the process of picking, installing and maintaining, the shape is irregular marks caused by bumps, which are reflected on the copy paper as irregular line marks and spot marks.

3. Electric shock puncture marks. It is caused by the partial conduction between the electrode wire and the photoreceptor drum to form an arc discharge, which is in the form of a circular spot, which is reflected on the copy paper as a blank missing mark with black dots.

4. Aging marks. The natural aging damage caused by the long-term use of the photoreceptor drum is manifested as the surface layer of the photoreceptor is peeled off or cracked, which is reflected on the copy paper as irregular black missing marks or a large area of fine ** mouth.

Be careful not to scratch the drum when installing.

Protect from light and prolonged exposure to bright light.

Handle with care and do not scratch the surface of the drum.

The tools you need are: printer, dry cotton swab.

1. Turn off the power of the printer and open the back cover of the printer, as shown in the figure below

2. Hold the green handle of the drum unit. Pull the drum unit outward from the device until it stops. The macro finger is shown in the figure below

3. Hold the handle of the toner cartridge and gently push the toner cartridge in the opposite direction to unlock it. Lift the toner cartridge upwards from the drum unit. Repeat this step for all toner cartridges. As shown in the figure below:

4. Please use a dry cotton swab to gently wipe the surface of the toner cartridge until the imprint is completely removed, and then the printer's photosensitive drum can be cleaned. As shown in the figure below:

The printer appears with a photosensitive drum insertion, providing you with maintenance technology, and repairing it is rewarded.

Hello dear! This is for you to find, the fiber lead printing machine prompts insertion of the drum indicating that the machine does not sense the drum or chip, I want to see if there is a crystal head in front of the drum rack to destroy the base, or first to figure out how the machine senses the drum frame is easier to repair. The maintenance of the photoreceptor drum is repaired by wiping the drum with chemical reagents, and the service life of the photoreceptor drum is extended by sunlight irradiation.

A photosensitive drum is a toner cartridge.

The toner cartridge is one of the core components of the printer's imaging, and the toner cartridge needs to cooperate with every step of the machine's work during imaging. in order to complete the imaging smoothly.

Generally, when the computer sends a print command to the printer, the printer will begin to execute the naming, the royal coarse ant first prints the data cable and passes it to the motherboard of the printer, and then the motherboard will assign different commands to other parts of the printer after the burial, first of all, the laser and the paper feeding system, the laser will receive the printing data, and then irradiate the surface of the toner drum core, at the same time as this action, the printer cartridge will start to feed.
