I have a 3 week old HP LaserJet CP2025 that was working fine. A few days ago I notice a light pattern is printing on ALL pages printed. The pattern is grey, on the left side of the page about half way or somewhat past. It is about 2 inches high by 1-1.5 inches wide - no difference in the pattern between pages, whether color or not.
It resembles what might happen with a bad fuser, or possibly some internal rollers/wheels are dirty.
We cleaned the rollers at the top and pulled the black cartridge and see nothing abnormal.
We ran the cleaning page function at least 8 times, no difference.
What do you think/what should we try?
