Am getting this regular marks across the right edge of my printed paper. Happens regardless if copying or printing. and shows up in different colors. is on HP Color Laserjet pro MFP m477 fnw. As usual, the HP support staff are unwilling to address. Since it is in color mixes unlikely that is the cartridge(s)? If is fuser, how to you access and how do you clean? Thanks so much.

The most likley cause of this defect is a delaminated hot roller in the fuser assembly and cleaning will not fix the problem. We have seen this in the shop several times. OEM HP replacement fuser sells for about the same price as a new printer. This problem can be exacerbated by the use of old firmware the does not include reliability fixes for transfer belt and fuser wear.
