Hp HP Color Copier 120


This printer printout shows a 120 vertical lines across the whole paper together with the orginal printout.
It happens only after the printer is heated up for a few hours later.
What is the problem ?

Maybeu should try cleaning the rollers inside the printer. Some can be very dirty. Does help some times...

You actually counted the lines? The vertical lines are an engine test. You can initiate one by looking at our troubleshooting section. If the lines match up, then you should replace the DC controller board. They are available in Moe's Deals section of the site.

It is caused by PCB board.
