Troubleshooting

Cause: The document you are printing contains an additional blank page.

Solution: Open the document file in your software application and remove any extra pages or lines at the end of the document.

Cause: The HP All-in-One picked up two sheets of paper.

Solution: If the HP All-in-One has only a few sheets remaining, load more paper in the input tray. If there is plenty of paper in the input tray, remove the paper, tap the stack of paper against a flat surface, and reload the paper into the input tray.

For more information, see:

“Load full-size paper” on page 35

Cause: The protective plastic tape was only partially removed from the print cartridge.

Solution: Check each print cartridge. The tape might have been removed from the copper-colored contacts, but still might cover the ink nozzles. If the tape is still covering the ink nozzles, carefully remove the tape from the print cartridges. Do not touch the ink nozzles or the copper-colored contacts.
