What is the problem that the printed files of the Beijing HP M608dn have black dots and black lines

After the summary of my colleagues, the following situations are obtained, please continue to read:

First. Copy the file black but print not black:

If there is dust or something on the slender glass strip on the far left side of the glass panel, you only need to wipe it with a rag.

Another situation is that the copy glass table is clean and the copy is black, then you need to check whether the glass of the scanning frame and the ** lamp are dirty, which needs to be cleaned by a professional maintenance master.

There is also a situation where the blackness caused by the displacement and light leakage of the manuscript feeder whiteboard, you need to remove the manuscript feeder whiteboard (generally the manuscript feeder whiteboard of the photocopier is glued on Velcro), extend the left side on the glass table, and then cover the upper cover and paste it.

Second. Copy and print documents are black:

Check whether the toner cartridge is damaged in the first line (you can see it when you open the side cover, if the toner cartridge is damaged, you can directly see the change in the color of the toner cartridge from the surface), generally the black edge or black spot of the toner cartridge is very regular, if the toner cartridge is damaged, then replace the toner cartridge.

After eliminating the problem of the toner cartridge, if it is still dark, clean the laser (the laser of most photocopiers is very simple to clean, you can generally find it by opening the lid in the middle of the machine, the laser is always very close to the toner cartridge, because it wants to shoot lasers at the toner cartridge), and cleaning the laser is generally just to wipe a few glass strips and hexagoprism in the laser with a paper towel.

If there is still a problem after excluding the laser, check whether there is any powder leakage or defective removal in parts such as the powder loading bracket and transfer assembly.

The last one is the failure of the fixing component, if the hot roller is damaged, there will be a partial black phenomenon, of course, the partial black phenomenon caused by the fixing failure is usually accompanied by the bottom ash, vertical bars, paper folds and even frequent paper jams.

It is recommended to provide **, to help you analyze, it may be a problem with the photosensitive drum or magnetic roller, depending on the spacing of the black dots.

I've seen the sample, and the black spots are caused by scratches on your drum core, which can't be repaired, and you need to buy a new drum core.

It may be caused by hard objects on the paper you use, I don't know if you usually use one side of the paper to print, there are marks like staples in the scars, so pay attention.

The reason for the black spot of the laser printer is basically that there is a problem with the drum core of the toner cartridge, and the cause and solution of the problem will be known below, and powder filling is also one of the reasons for this phenomenon.

1. If there are black spots or black lines, the problem is that if there are many regular black spots or black lines in the drum core powder, in general, the drum core is dirty or worn, and the drum core is dirty and easy to deal with. On the other hand, if you put the drum core on the ground during a powder change, or if you touch a hard object such as a screwdriver, the drum core will wear out. Because the drum core is made of photosensitive material, the repair method is to use a photosensitive drum polishing cleaner to repeatedly rub the surface of the photosensitive drum 3-4 times, be careful not to leave the detergent on the surface of the photosensitive drum, and then put it back on the drum frame to use.

Of course, if the drum core is too worn, then the drum core must be replaced. The drum core is not expensive, about 100 yuan, and it is generally possible to add three to five times of powder, but the premise is to pay attention to the model and quality, and do not replace it casually. If the same situation still occurs when the drum core is replaced with a new one, then whether the scraper and charging stick are damaged.

2. The font fades or there are white lines, the problem is in the magnetic stick printer magnetic drum If the font printing is faint or there are some words that are not clear in the middle of the white line, then the first thing to check is the powder on the magnetic stick. If it is after powdering, it is common for the brand of toner you to fill is different from the brand you originally used, and the font will fade when the two different brands of toner affect each other. The solution is to clean the original remaining powder on the magnetic stick and then fill it with powder.

It should be noted that the drum core should be protected when it is removed, because the drum core cannot be exposed to strong light, including sunlight and harsh lights, and finally placed in a black bag for cleaning.

Remember, don't think that "one powder goes the whole world", because the composition of existing printer toner is a single powder (i.e., the composition includes only one raw material - toner) and a dual group powder (i.e., toner + carrier), for example, Epson uses non-magnetic toner, and HP uses toner containing ferric oxide, and the two are not interchangeable.

Printer photosensitive drum core printer toner cartridge powder filling to the toner cartridge is the greatest damage, the more times the powder is filled, the printing quality of the toner cartridge is getting worse and worse, generally when the number of toner times is more than 3 times, there will be some regular black spots, and this problem will become more and more serious with the increase in the number of printing, when the printing handwriting is blurred or printed out of a black mark, the toner cartridge will be scrapped, many people choose to replace the new toner cartridge. In fact, this waste selenium is still available, but you need to repair it by hand, and the main work of the restoration is to replace the photosensitive drum and refill the powder. In the process of replacing the drum, the waste powder must be cleaned up.

It should be noted that the newly bought photosensitive drum has a black anti-** seal, which should not be torn off before installation to prevent **, and can only be torn off after the installation is checked.

Yes, if you use an inkjet printer, it may be an ink cartridge plug, if you use a laser printer, then there are the following 2 possibilities, 1It could be that your drum core is broken 2It may be that the waste toner bin of your toner cartridge is full, and you can clean it up!

If the toner cartridge is missing in the middle, it means that the toner cartridge has no toner! Shake the toner cartridge to make 10-20 shots!

Check whether the ink inside the cartridge is poured out, take the cartridge out and wipe it off, and then put it back in.
