NOTE: When the printer operates in ink-backup mode, a message is displayed on
screen. If the message is displayed 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.

CAUTION: Do not touch the print cartridge ink nozzles or copper contacts.
