Have you tried cleaning the document feeders Scan Glass? (small glass under doc feeder ~ 1" by 9") Most times there is dirt spot on this glass, causing a shadow on scans and copies.
Try copying from the large glass by lifting doc feeder / platen cover and manually placing original. If no line copying or scanning manually from large glass, then small scan glass is deffenitely the culprit. Hope this helps.

I get a blank line across all sentences when using black ink in either print or copy mode. I cleaned the cartridge while a little bit better it is still there. thanks


Wipe the underside of the cartridge with a soft tissue and then try cleaning the cartridge again, several times if need be. Blocked jets seem to be the problem here

HP Officejet J5780 All-in-one Injet prints a grey line down the right side of the page when copying using the automatic document feeder. It does not show up when printing; and it does not show up when...


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.
