Troubleshooting

Ink low

Cause: At least one of the print cartridges is estimated to be low on ink and might need to be replaced soon.

Solution: Have a replacement cartridge on hand to avoid printing interruptions. You do not have to replace the cartridge until print quality deteriorates. If you have installed a refilled or remanufactured print cartridge, or a cartridge that has been used in another printer, the ink level indicator will be inaccurate or unavailable.

For more information on print cartridges, see “Troubleshoot print cartridges” on page 95.

Need alignment or alignment failed

Cause: The incorrect type of paper is loaded in the input tray.
