The fuser is a replaceable maintenance part in the printer that melts the toner so it stays on the page. It can also be caused by a damaged or dirty mirror that reflects the laser beam or it can be caused by a damaged fuser unit. If the drum is damaged in any way with a finger print or dirt on it, it can cause sections of the print out to be missing because the dirt is blocking your image from being rolled on to the page. A drum is a replaceable maintenance part of the printer and can either be built into the toner cartridge, or separate from the toner located on top of or underneath it. This drum then rolls the toner onto the paper as it passes. The laser printer works by a laser beam ‘sketching’ the image of what you are printing onto a green metal cylinder called a drum or photoconductor unit. There are a few possible causes of this so you may need to check each in a process of elimination to figure out what’s happening but in most cases, the problem is caused by the drum.
Missing areas of print (either always in the same place or not) Remember to be careful and if you are at all unsure, find a printer technician who is experienced in cleaning the printer.
Warning: make sure you wear gloves and don’t touch the transfer belt film with your fingers or the hoover, you could leave a mark that will cause additional print problems. If all else fails, you may need to replace the transfer rollers / transfer belt.
