"Printing in ink-backup mode" message

Cause: 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.

Solution: 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.

To remove plastic tape from a print cartridge

▲Hold the print cartridge so that the copper strips are on the bottom and facing toward the printer, and then carefully remove the plastic tape.
