Question about Brother DCP-7040 Laser Printer
Printed or copied pages have a grey background. The cartridge was changed and that helped for a while, then the poor copies returned.

Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.
Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).
Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.

Change out the toner first and then the drum. Also be sure there is not excess toner underneath where the toner is installed. If so clean that out with a dry cloth.

This is caused by dirt/debrise on the ADF (automatic document feeder) scanner glass. You need to open up the feeder where your originals are fed in and look for a strip of glass that runs from front to back. It is about an inch or so wide. You need to clean this glass to get rid of the lines. Some models have this glass just to the left of the large main glass, but in your case I beleive it is in the feeder itself.

How do I clean white or black spots on printed documents?
First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:
The OPC drum is photosensitive so do not touch it with your fingers.
