"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.
