a refilled or remanufactured print cartridge, or a cartridge that has been used in

"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.
1 Remove plastic tape
CAUTION: Do not touch the print cartridge ink nozzles or copper contacts.
Touching these parts will result in clogs, ink failure, and bad electrical
connections. Do not remove the copper strips. They are required electrical
contacts.
