Printer is a common office equipment, and one of the common problems is that black powder is not normal. When the printer's black and pink color is abnormal, it will lead to poor printing effect and common problems such as color block, white line and gray shadow. The following is the reason why the printer black powder is abnormal and the correction method.

First of all, compact is not suitable.

The toner cartridge used by the printer needs to match the model of the printer. If mismatched toner cartridges are used, black and pink will be abnormal. In this case, the adapted compact must be replaced.

Second, there is a gap in the contract.

Incorrect or careless installation of the printer ink cartridge may also lead to cracks in the ink cartridge, white lines or gray shadows when printing. The compact needs to be reinstalled to ensure a tight installation.

Third, the cleaning is not thorough.

Whether it is an ink cartridge or a powder cartridge, residues and foreign bodies will appear after a period of use. If it is not cleaned in time, it will affect the normal work of the printer. In this case, it is necessary to thoroughly clean the printer, including cleaning the gear, cleaning the ink cartridge or the installation position of the ink cartridge, etc.

Fourth, the conveyor belt is slack.

Inside the printer, the conveyor belt is a key component. If the conveyor belt is slack, it will affect the printing quality. It is necessary to manually adjust the tension of the conveyor belt to ensure its compactness and balance.

In a word, printer black powder abnormality is a common problem, which needs to be solved in time. Most problems can be solved by replacing the compact, reloading and cleaning. At the same time, regular maintenance of printers can also improve the stability and service life of printers.
