My HP LaserJet 4100n started producing vertical smudges with horizontal lines and repeating ghost images of text almost overnight. I ran a ten-page print job just now, and the first page is lighter than subsequent pages.
The aftermarket high yield toner cartridge is half full, and hasn't been a problem for thousands of pages.
There were less than 70,000 sheets since the last full maintenance years ago, but I went ahead and bought a new factory HP maintenance kit of fuser and rollers. Before installation, I removed all trays, duplexer and envelope feed, wiped interior surfaces and blew out dust with canned air. Installed kit. No improvement.
I re-cleaned the areas specified by the manual, and manually ran a "process cleaning page." No improvement (photo below).
Any help will be much appreciated. Thank you!
Edited to add: I've ordered a genuine OEM HP C8061A toner cartridge.
