Operating System: Microsoft Windows 10 (64-bit)

Hi, 

I have an issue with my HP 3015x Laser printer. 

It will print a series of vertical lines on the paper, please see photo for a sample. 

What could be this issue here? 

 

Some points I have read on this forum include he following:

Check toner contacts- cleaned and OK. 
 
I would look more towards the high voltage board or the contacts going from that board to toner cartridge.
Random weirdness- sounds like a voltage issue to me too. Suspect parts would be-
Engine-control unit (ECU)
DC controller
Low-voltage power supply
High-voltage power supply
Laser Write Unit.
 
swap out the printer power cord and network cable as well- i have seen power cables go bad and network cables with kinks in them cause some crazy things.
  • the problem could also be with the laser write unit, HVPS- or one of the boards responsible for image formation.

Thank you
