Print cartridge is faulty or not installed properly
The printer cannot print if the print cartridges are faulty, or if they are not installed properly.
To resolve the problem
1. Raise the printer cover.
2. Do one of the following:
– If an error message is displayed on screen, remove the print cartridge that is
named in the error message. Go to step 3.
– If an error message is not displayed, remove and reinstall each print cartridge.
For more information, see Installation instructions.
If this does not resolve the error, continue to step 3.
3. Manually clean the print cartridge.
4. Reinsert the print cartridge in the printer and close the printer cover.
If this does not resolve the error, the print cartridge is faulty and must be replaced.
Note You can print with one print cartridge in ink-backup mode if you do not
have a replacement print cartridge available. For more information, see Ink-
backup mode.
5. If the error is still not resolved, visit HP Technical Support at www.hp.com/support.
"Printing in ink-backup mode" message
When the printer detects that only one print cartridge is installed, ink-backup mode is
initiated. This printing mode lets you print with a single print cartridge, but it slows the
printer and affects the quality of printouts.
If you receive the ink-backup mode message and two print cartridges are installed in the
printer, verify that the protective piece of plastic tape has been removed from each print
cartridge. When plastic tape covers the print cartridge contacts, the printer cannot detect
that the print cartridge is installed.
