Printer Frequently Leaks Toner & Pages Appear Black Lines? 90% of Faults Root in Wrong Selection of Cleaning Blade
Printer Frequently Leaks Toner & Pages Appear Black Lines? 90% of Faults Root in Wrong Selection of Cleaning Blade
2026-08-17
36Many administrative operation and maintenance personnel in commercial office scenarios have encountered these recurring frustrating problems: the printed pages always carry penetrating vertical black lines, excess toner overflowing from the waste toner bin leaves the entire interior of the device covered in black stains. Even if you manually wipe the photosensitive drum and clean the blade repeatedly, the fault can only be relieved temporarily, and the problem will reappear after printing only dozens of pages. The root cause of the vast majority of such problems is not the damage to the photosensitive drum hardware, but the wrong selection of the cleaning blade.
Many cheap and inferior generic cleaning blades on the market are made of ordinary recycled polyurethane material, with insufficient edge grinding precision. They will suffer wear and deformation after less than a few thousand printing cycles. Not only can they not completely scrape off the residual waste toner on the surface of the photosensitive drum, but the residual hard impurities will also scratch the surface of the photosensitive drum back and forth along the deformed blade edge, causing irreversible permanent scratches. All subsequent printed pages will always have a black line at a fixed position. In severe cases, a large amount of waste toner will accumulate and overflow, contaminating the circuit components inside the machine, directly causing the digital copier worth tens of thousands of yuan to be scrapped prematurely.
