Question about HP LaserJet 6p Printer
I had black thin lines (horizontally) on each page. Was told to shake cartridge. Did so, now I have multiple black horizontal lines on my printing. Help?
Usually this is a sign of a bad PCR (primary charge roller) in the cartridge. Replacing the cartridge will fix the problem. Another possible but unlikely cause is toner melted onto the fuser roller. I've also seen damage to the OPC (organo-photo conductor drum) caused by volatile plasticizers in the pcr coming in contact with the drum and damaging it. The OPC drum and the PCR are part of the cartridge, and it's easy enough to replace that.
