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 plastic tape has been removed from each print cartridge.
