Printing in ink-backup mode

Solution: If you receive the ink-backup mode message and two print cartridges are installed in the product, verify that the protective piece of plastic tape has been removed from each print cartridge. When plastic tape covers the print cartridge contacts, the product cannot detect that the print cartridge is installed.

Solve a problem

1Copper-colored contacts

2Plastic tape with pink pull tab (must be removed before installing)

3Ink nozzles under tape

Cause: When the product detected 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 product and affects the quality of printouts.
