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.
