Line down the middle of the page when I "copy"

This has only been happening for the last few days with my HP Officejet J5780 All-in-One scanner/copier/fax machine.

I can "print" documents just fine, with no extraneous line down the middle of the page (top of the page to the bottom, right down the center). But once I stick the same page in the automatic feeder to be copied, every page gets a line down the middle of the page. Some pages get two lines, about an inch and a half apart.

I remember about ten years ago when I had to clean the "heads" of a copier or printer when this happened. Can I clean the heads (or whatever it is, now) with this one? If so, how do I do it?

Thanks for your help.

    My HP office V series all in one printer works fine when printing from the computer. When I copy using the document feeder, two black lines appear running vertically down the page.

lift the feed area and look at the small glass plate where the auto feed paper is actually scanned. That needs a good cleaning. Since the paper runs across it even a tiny little obstruction such as paper left from a paper jam or a dot of ink from that pen you used to unstick that last paper jam (maybe its just me??). That one dot turns into a line when the paper rolls across it. Clean well and the line will dissappear.

HP J5780 Problem-Line on printed pages


most likely you have a flat spot on the roller.
that is exactly what is going to happen, when the paper hits the flat spot or a low spot. the paper stops and skips. them the print is coming out smeared.
you can get a repair kit or replacement roller from HP.

  4. Turn the product on.

your printing program needs a template, based on the label makers specs. That's usually what causes that, not the printer itself.

got backup?
