Could be that there are a mark on the drum itself or some dirt, remove the drum unit and inspect the surface , by rotating the drum , becareful not to touch the drum as it will leave marks on the surface

Again, this was actually HP Laserjet 3800. Problem solved by chatting with HP, and them having me go into a diagnosis mode that disabled cartridge check. Then, I removed the cyan cartridge, the dots went away. They then had me put the black into the cyan slot, and not dots appeared. I had backup toner on hand, swapped in a new cyan and magenta, and all was good. HP agreed to replace the cartridges.

I would have guessed the trouble shooting steps you first performed. It could still be a bad imaging drum. Or a fuser. Not sure if this model has a replaceable fuser or not.

Prints black dots at bottom of page - photoconductor was replaced earlier today


The black dots could be a few things, the most likely would have something to do with the drum area because the dots didn't appear until after service. If the dots are only about an inch apart it is probably the charge roller. If there is only 1-2 dots per page, the issue is likely with the drum. These figures are assuming you are running 8 1/2 x 11 paper with the long edge being fed in first. If this is the case, you can change the paper to feed with the short edge first and this may get you by until the technician gets back out to fix it.
