The printed page has longitudinal black track failure maintenance.

The cause of longitudinal black road is mainly due to the damage of photosensitive drum, the failure of photosensitive drum scraper, the damage of magnetic roller, the damage of magnetic roller, or the operation of different axes. The printed page has the following maintenance methods for the longitudinal black track failure. First, check whether the scraper is stained with dirt or scraps. If the scraper is not clean, clean up the dirt on the scraper. If the scraper is clean, then check whether the drum of the photosensitive drum is lubricated. If the scraper is not lubricated, apply a layer of lubricating powder to the scraper and see if the fault is disappearing. If the failure is still, replace the scraper. If the scraper is normal, then check whether the drum is worn or scratched. If the photosensitive drum is worn or scratched, the cf410a toner should be replaced. If the photosensitive drum is normal, clean the fixing device. Gray image print out of the bottom or road maintenance.

There is a clear bottom ash on the printed image. It is usually a problem with a drum or a toner. And print the image color unevenness. There is obvious way, is generally caused by toner. If white paper is printed, it may be that the installation of the toner cartridges is problematic or the selenium drum is damaged. For obvious bottom ash failure image printed. The first check is not caused by the toner "bottom ash (print fault if used poor quality toner), if it is to replace the toner; if not, it may be caused by aging or damage of the photosensitive drum, can be processed with the following toner aging processing method.

To print the image color is not uniform, there are obvious fault confessed.

The first magnetic roller from the outside cannot see the toner. If you see some places on the magnetic roll powder, in some places there is no powder. Show that the toner has exhausted, please add toner. For printing out the white fault, first remove the toner cartridge, re installed, to see if the fault is removed. If the fault is still then, check the printer other parts (such as laser scanning system, etc.) there is no problem. If no other problem is the damage caused to replace the toner cartridge. After a long time, the output text and image will be blurred, bottom ash is aggravated and font size is longer. The reason is usually due to the aging of the membrane on the surface of the hp toner cartridges. This will remove the toner cartridge surface fatigue, exposing the photosensitive surface not aging. Be careful when cleaning, avoid nails and other hard objects will scratch the film cartridge. Not to force too much. Worn and make the selenium drum scrap.
