What are the faults of the photocopier with ghosting?

First of all, check whether there is a problem with the toner, but the customer has been cooperating with us, and the powder has always been the original powder provided by our company, so this possibility can be ruled out, and then the only way to check is that the fuser roller is broken, and after checking, the fuser roller is indeed sticky with toner. So the only way to do this is to remove the fuser roller and clean it. When taking the fuser roller, the back cover should be removed first, then the side door should be opened, the screws at both ends of the fuser roller should be removed, and then the three sets of connected lines behind the fuser roller should be taken out.

After taking out, the upper and lower rollers of the fuser should be separated, and the spring on the side of the fusing roller should be paid attention to when he leaves, and the toner on the upper roller can not be cleaned immediately after separation, the three connecting wires on the fuser roller should be reconnected to the machine, and then the machine will be turned on, and then the toner on the roller will be cleaned after the fusing lamp is baked, and it is easier to clean. After cleaning, it is OK to restore it, but if you want to make the fixing roller not stick or less toner, you can enter the maintenance procedure, and then use 43-1 to lower the fixing temperature, generally on the 4, adjust to 3 on the line, if it is too low, there is a right can not fix, and finally restore the back cover, on the line.

The principle of printer imaging is to heat and pressurize the toner attached to the printing paper through the heating component, so that the toner is tightly attached to the printing paper. If a printed document is ghosted, there are three possible areas of the problem. quality problems with the paper used; quality problems with the toner in the toner cartridge; Failure of the laser printer heating element.

Solution, in view of the problems in the above three aspects, the first thing should be to switch to better quality paper and reprint to see if there is still ghosting. If ghosting persists, confirm that the toner in the cartridge is original**. If the printing ghosting still occurs despite the use of high-quality printing paper and original toner, then the cause should be that the surface of the printer's heating element is damaged, and the toner sticks to the heating element, resulting in printing ghosting.

When there is a hardware failure, it is time to send the printer in for repair. If there is a single color with ghosting, you can change the corresponding color of the toner cartridge to try, after replacing the toner cartridge or not, if there are multiple colors with ghosting, you can follow the following method to calibrate the printer to try, the following is the method of calibration: press the checkmark button on the printer, press the system setup button to the right, press the checkmark again, find print quality twice to the right, press the checkmark twice, press the calibrate now, press the checkmark button twice, If there is still a problem with ghosting, remove the printer fuser component, disassemble the fuser part, clean the fuser roller (generally the fuser roller is stained with toner), and reinstall it.

In addition, printing ghosting means that the imaging is normal, but there will be a relatively complete image behind the normal image, usually the ghosted part will be much shallower than the normal image, and it is regular that there will be shallower ghosting at a certain distance.

Transfer printing in laser printers refers to the process of the number of carbons forming an electrostatic latent image on the drum core from the drum core to the paper under high transfer pressure. If there is a failure in the transfer (such as the transfer voltage is wrong), the toner can not be completely transferred to the paper, and with the rotation of the drum core, the image part of the electrostatic latent image will also be transferred to the paper in the next cycle, which will cause the phenomenon of laser printer ghosting. Clean the toner and use a special toner (if you use the wrong toner, the toner will cause the printer to ghost), reset the paper type (when the paper is set to thick paper or film, the transfer voltage will be higher than that of ordinary paper), and check whether the transfer rollers are good at both ends and whether the transfer is normal.

Fixing means that the toner on the paper is hot-pressed into the paper fiber at a high temperature, so that the toner is very paper combined and will not fall off.

The photocopier is ghosted, which could be due to the following reasons:

1. Paper quality problems: Reprint with used paper, but forget to remove staples or paper to stick a piece, and use labels or sulfuric acid paper, which will cause damage to the surface of the printer's heating components.

2. The quality of the toner or the toner cartridge is caused by it. There is a big gap between the toner and the original toner in terms of particle size, hardness, melting point, etc., which is very easy to cause damage to the heating component of the printer. Poor quality toner can easily cause damage to the printer, such as ghosting.

3. Paper jam problem, when dealing with paper jam problem, remember not to pull hard, so that the toner cartridge is easy to be damaged, but you should first remove the toner cartridge of the printer, and then take out the jammed paper.

Solution, in view of the problems in the above three aspects, the first thing should be to switch to better quality paper and reprint to see if there is still ghosting. If ghosting persists, confirm that the toner in the cartridge is original**.

If the toner cartridge is cleaned and the printing ghosting still occurs despite using high-quality printing paper and original toner, then the cause should be that the surface of the heating element of the laser printer is damaged, and the toner is stained on the heating element, resulting in printing ghosting. When there is a hardware failure, it is time to send the printer in for repair.

Common functions of photocopiers.

Copying: The copy function is the core function of the digital multifunction machine, which can completely replace the ordinary photocopier, as the copy equipment in the office, its copy performance and function far exceed the traditional copy machine, not only the copy content can be stored, but also can derive a lot of characteristic copy functions. For example, functions such as zoom copying, sea copying, business card copying, and combined copying can help users achieve a variety of very practical document copying functions.

Printing: Although it is an extension function of the multifunction machine, it can be completely used as a printer, which is completely consistent with the printer in terms of printing speed, printing quality, paper processing capacity, and printing function, and is even better than ordinary printers in terms of printing load and single page printing cost. Moreover, it has maintained the same technology as the printer field in terms of confidential printing, storage printing, and network printing, and even in the development trend of color, the digital multifunction machine has kept pace with the printer field, and there seems to be no reason to exclude it from the printing field.

Scanning: The scanning function is also an extension of the copy function, compared with ordinary scanners, the function of the digital MFP is more oriented to document scanning, there is no one-sided pursuit of scanning resolution and color depth, but there is no problem with the text and ** scanning in the document. Its scanning speed, batch scanning ability, and double-sided scanning ability are incomparable to ordinary scanners.

The quality of the paper used, the quality of the toner in the toner cartridge, the laser printer.

Faulty heating elements.

In view of the above three problems, the first thing should be reprinted with better quality paper to see if there is still ghosting. If there is still ghosting, you should confirm that the toner in the toner cartridge is or the original ** toner. If you are using high-quality printing paper.

In the case of the original toner shirt Sakura, the printing ghosting phenomenon still occurs, then the reason should be that the surface of the heating element of the laser printer is damaged, and the toner is stained on the heating element, resulting in printing ghosting. When there is a hardware failure, the printer needs to be repaired.

It is generally caused by toner or toner cartridge, it is recommended to clean the toner cartridge part, and if there is a problem with just adding toner, it is recommended that you pour all the toner inside, clean the inside and re-add the toner, because if the toner is mixed with different brands of powder, it will cause bottom ash and ghosting.

toner or toner cartridges.

It is recommended to clean the toner cartridge part, it is a problem that just adds toner, it is recommended that you pour all the toner inside, clean it, and re-add the toner inside, because if the toner is mixed with different brands of powder, there will be ghosting.

It's obviously a fixing problem.

If the fixer is not broken, you just need to clean it.

But be careful, non-professionals, please don't try it yourself, the temperature is very high, find a repairman to fix it.

There is a problem with fixing, and it may also be powder.

There are many reasons why a photocopier may experience ghosting, and here are the main ones:

2.Scanner issues: If the copier's scanner is malfunctioning or contaminated with dust, it can cause ghosting while scanning.

4.Damaged Drum Damage: Damage to the drum may result in poor light scrambling refraction, resulting in ghosting.

5.Lack of luggage in the printing roller: Problems with the rubber roller may cause uneven printing on the rubber roller, resulting in ghosting.

6.High temperature environment: High temperature environment can cause the parts in the photocopier to deteriorate or deform, resulting in ghosting.

7.System problems: Failure of the copier's system or imperfect program may also lead to ghosting.

These problems can lead to ghosting in the copier, and if this happens, the problem should be diagnosed in time and maintenance measures should be taken accordingly. These include: replacing the light source, cleaning the scanner, replacing the toner cartridge, replacing the drum, replacing the rubber roller, lowering the temperature, updating the system, etc.

The problem of ghosting in photocopiers is common in many copiers, which not only affects the effect of printing, but also destroys the quality of the output, which greatly affects the efficiency and effect of the work. For this kind of problem, we can fix it in the following ways:

1.Clean the scanner.

Scanner dust and dirt can also cause ghosting in prints. In this case, we can clean the scanner to solve the problem. First of all, we have to turn off the copier, then take out the toner cartridge, use a clean, soft cloth dipped in alcohol or cleaning liquid, wipe the lens and glass and other areas on the scanner, wait for it to dry and reinsert the toner cartridge, after turning it on, just print once.

2.Replace the toner cartridge.

The toner in the toner cartridge will also affect the print quality, and if the cause of the toner cartridge ghosting is because it has run out, then you need to replace it with a new toner cartridge to solve the problem. It is important to note that do not touch the toner cartridge or the internal sensor with your hands when replacing it with a new one, as this may cause malfunction.

3.Adjust**.

**Incorrect value setting can also cause ghosting issues. In this case, we need to make **adjustments, according to different printers, some printers will have a **adjustment component, and the slip can be adjusted according to the instructions above to solve the problem of ghosting in printing.

4.Clean the fuser.

The correct way is to disassemble the copier, take out the fuser and clean it, and then assemble it after drying.

In short, the problem of ghosting printed by the photocopier should be dealt with in time and solved through the above methods to ensure the normal use of the printer.

1. Clean the charging roller of the powder box (the one that sticks to the powder), wipe the powder on the right side, turn it a few times, and wipe it all clean.

2. Put it in and try it. If not, clean the toner cartridge, electrode wire, wire mesh, and brush. If you have the conditions, change a drum to the core, forget it if you don't have it, install it and try again. If you change the drum core, it still doesn't work. It's time to think about cleaning the laser.

3. The scanning table must be removed, then the left and right side covers must be removed, and the back cover must be removed. There are two screws on each side to tie the chain to the black box of the laser, after removing it, open the black box, and gently wipe the hexagram with a good toilet paper (don't get alcohol or anything). Then put it on.
