HP OfficeJet J5780 Vertical Black Line Prints when copying or scaning only. Cleaned rollers and changed black ink cartrigde. Still problem.


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.

Oce 3121 coping machine make random black line shadows


if you are getting copy quality issues on all aspects of the machine, IE, printing, copying, ADF, it looks like then you might need a new drum installed. please contact your local service department for service and make sure if you need supplies, to have those on hand before calling a tech to come service the machine. drums, developers, and toner are considered a supply item and are NOT carried by technicians unless otherwise stated in your local contract.

ADF Reader, Black lines


Open ADF (automatic document feeder) cover and clean scan glass underneath. White out or post-it notes are notorious for leaving behind residue on glass when scanned. Any dot, spot or dirt will show up as a black line due to shadow effect.

White line and very, very dirty copies


the nealy black copies sounds like the drum is going, try adjusting the exposure to light, if it comes out with the whole page the same way but just lighter than change drum. White line sounds like there is something on the coronas.
