In the ink-backup mode, the printer operates with only one print cartridge. The ink-backup
mode is initiated when a print cartridge is removed from the print cartridge carriage.
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.
1 Remove plastic tape
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.
