What s the deal with the photocopier that made a lot of black streaks?

The reason why there are a lot of black streaks in the photocopier's copying: the toner cartridge is leaking.

Solution: In general, the drum core is dirty or worn, and the printing can be restored to normal after the drum core is cleaned.

Another case is if the drum core is placed on the ground during the powder change, or if the drum core touches the screwdriver.

and other hard objects, the drum core will be worn. Thanks to the photosensitive drum.

The core is made of photosensitive material, so the repair method is to repeatedly wipe the surface of the drum with drum polishing cleaner 3-4 times.

Be careful not to leave the cleaner on the surface of the drum and then put it back in the drum holder and it is ready to use.

1. Clean the optical scan first.

2. Check the imaging unit.

3. Check the fuser unit.

Streaks appear on the photocopier's copy. Streaks are a common problem, occurring in the form of light streaks, in the absence of toners, and black streaks, which look like spills out of toners. The problem shows that the toner doesn't stick where it should be on the paper.

There are generally several reasons for this:

1.Cleaning is required.

Over time, the internal components of the copier collect dust, dust, and dirt. Failure to properly clean one of the machines inside can affect its performance. Running naked often is a sign that the corona wire is dirty, especially in older machines.

Corona wire at the bottom of some copier, put the charge on the paper, so the toner will hold a piece. Please refer to the manufacturer's instructions or contact a professional copier's repair service for instructions on how to clean parts for a particular machine. Cleaning your copier in-house every two months can help prevent streaking.

Similarly, clean the glass copy boards, window cleaners to avoid marks on the paper, which can be streaks and smeared copies.

2.Toner issues.

A potential problem with the toner cartridge can cause a couple to run naked. One is the cartridge, which is not sufficient toner. Most photocopiers warn you that you need to replace it if you run out of toner.

Another problem is that the cartridge needs to be cleaned. Many cartridges use the copier's drum charging cable. If this part is dusty, the drum will not charge the paper normally and can lead to streaking.

Streak running can also cause excess toner to spill out of the reservoir of the cartridge.

3.Paper issues.

Photocopier five flower copies, because sometimes there will be something wrong with the paper. If you use anything other than copy paper, it may not be able to charge properly so that the toner will stick. Another potential problem is that low humidity can cause static electricity to document and prevent if properly charged.

To avoid this problem, store the paper in an area with moderate humidity, especially on cold winter days. If you suspect that the paper currently loaded in the machine is static, stack it, hold it with one hand, and fan the page with your thumb and forefinger on the other.

4.Hardware issues.

Other issues cause streaking to do your copier's hardware. In particular, a malfunction of the drum unit will not be able to transmit a clear image copy paper and will produce streaks. If it doesn't charge properly, it may need to be replaced.

Hardware issues are usually taken care of by a professional copier repair technician.

1. The black bar on the copy is parallel to the direction of the paper road, the reason is: the main charging electrode wire is dirty, rusty or knotted; There is debris in the path of light, and stains obscure the light; Localized contamination or damage to the power dissipation lamp; Dirt or scratches on the surface of the drum The cleaning scraper is bruised, chipped, or heavily soiled; The surface of the fuser roller is dirty or scratched.

2. The black bar on the copy is perpendicular to the direction of the paper road, the reason is: the developing device is polluted; , axial scratches or spots on the surface of the drum; The fuser roller is dirty; The scanning mirror is loose.

Solution: There is an accessory on the printer called toner cartridge, a green cylinder, which is damp. Take a hair dryer and blow it.

When the printer prints the file, there will be a white horizontal line and white bar, which tells us that the printer should be cleaned, and the white horizontal line will disappear after cleaning.
