So, the fog on the drum is a scratch, or are you saying that
there's a toner image of the fog on the drum? Use a piece of tissue
and (very!) carefully wipe at it to see if it comes off.
If it doesn't, then the drum is screwed, which (on most printers)
means the cartridge is screwed. If it does, then there may be a
piece of crap on one of the corona wires. There's a slot that runs
the width of the toner cartridge that is covered on the inside by a
flexible piece of black plastic film. Use the corona wire cleaner
(the green thing with the felt tip) and stick it in there in the
obvious way, and run it back and forth a few times.
Back in June
(2008), I wrote about my HP IIISi laser printer
complaining "50 SERVICE". [...]
Today I picked up a new fuser and replaced it, and now it works.
However, there's a vertical line of what I can perhaps best
describe as
fog on every page. Last time I had something of the sort, replacing
the toner cartridge (which includes a roller of some sort) fixed
it. I
slid the door over the roller open and the fog is visible on the
roller
too. Perhaps interestingly, this fog was not present on the first few
pages printed (which were test pages); it showed up while I was
printing "real data". Also, the thing is giving me a lot of paper jams with
the page
stuck in
the paper path after the fuser - sometimes they register as internal
jams, sometimes as output jams. It's not consistent, but frequent
enough to be annoying. Any ideas what could be causing that?
There could be something sticky on the fuser roller. On these
printers, there is (or should be) a white felt pad stuck to a plastic
frame that sits atop the fuser roller and wipes it as it rotates.
Most people never bothered with that pad, to their detriment...you're
supposed to change it when you change the toner cartridge, and new
toner cartridges (usually) come with one. That pad is saturated with
fuser oil; it cleans and lubricates the fuser.
