There are a series of mirrors on the carriage that moves back and forth under the original glass. When dust builds up on these mirrors it makes the copies darker. Since the dust is blown by the optics cooling fan it does not collect evenly which causes areas of the copy to be darker than the others. On this machine you just have to remove the original guide plate which is the plate with 4 screws in it and has the document size numbers on it. Once that is removed the glass can be lifted out. With the power turned off just gently pull out the scanner bar. The part that initially comes out has 1 mirror as well as a silver reflecting strip on it. Clean both. Now the assembly that follows the first assembly out has 2 mirrors on it. 1 facing downward and 1 facing upward. Clean these 2 mirrors. Re-nstall the glass and plate. Turn the machine on and let the scanner unit home itself. Once warmed up make a copy to test. Cleaning these surfaces will usually correct the problem. There are 2 more mirrors under the black box under the glass but those do not get as dirty and they are harder to get to.
Good Luck and Thank You for using Fixya.

Black line down the center down the page


If it is a lazer printer a score on the photosensitive drum will leave a black line. Sometimes it is less grevious cace of an accumulation of ink leaving a line around the drum. This can happen when printing many dark background or full bleed copies. These drums are seensitive but can be carefully cleaned. Work away from direct strong light.

My Xerox XC830 copies are dark and have lines but otherwise present the image. How can I make the background white again.? Thanks! Ron


You probably needs some servicing. Drum, developer and other parts have a life cycle and once it's exceeded you can start having copy quality issues. Unfortunately there is no easy fix.

Paper has dark marks down middle


If you make a copy, does the copy have dark areas down the middle of the page? If so, remove the toner cartridge and gently roll it around to redistribute the toner inside, maybe even replace the toner cartridge if you've had it a long while. If you still see unevenness, you may need to have the machine looked at.

If the copies you make on your machine look fine, then I would suspect that the person sending you the fax has a dirty scanning element. Check with them to see if they can clean the scanning element and it should improve the fax quality.
