The black printing is becoming faint in parts.
I haven't yet run a cleaning cycle, but on looking at the cartridges the
imaging drum on the black catridge has some gunk adhering to it.

I have Googled for instructions, but HP say replace it, and the more
specific sites seem so far to be all about stripping and rebuilding (i.e.
remanufacturing) the cartridge, which looks over kill.

Has anyone cleaned this (or similar) laser printer?
I assume some Isoprpyl alcohol would clean the visible part of the drum
but at the moment the drum doesn't want to rotate when I try and twiddle
the plastic bits.

New set of toner probably called for.
I am not using original HP so perhaps the printer software isn't good at
estimating remaining toner but the printer seems to think that all
cartidges have some life left.

I have no idea how to accurately estimate what is left, and it is years
since I changed the original (HP) shipping set for these remanufactured
cartridges.

Advice and experience is, as usual, very welcome.

Cheers

Hmmm....ran the cleaning cycle with standard paper then read it should be
acetate (which I thought you shouldn't feed through laser printers).

Anyway, it seems to be printing OK at the moment, although before a test
print seemed fine (bold black) but some normal printing didn't.

We shall see.

I should really take the black cartridge out again to see if the crud has
gone away.
Fun for another day.
