7. Close the front door.
Use single cartridge mode
Use the single cartridge mode to operate the printer with only one cartridge. The single cartridge mode is
initiated when one of the following occurs.
● There is only one cartridge installed in the carriage.
● A cartridge is removed from the carriage if there are two cartridges installed previously.
NOTE: If the printer enters the single cartridge mode when two cartridges are installed in the printer,
verify that the protective piece of plastic tape has been removed from each cartridge. When the plastic
tape covers the cartridge contacts, the printer cannot detect that the cartridge is installed. If there is no
plastic tape on the cartridges, try cleaning the cartridge contacts. For information about cleaning
cartridge contacts, see Ink cartridge issues .
To exit the single cartridge mode
● Install both the black and tri-color cartridges in the printer.
Ink cartridge issues
If a cartridge has a problem, you might get a cartridge problem message.
If an error occurs after a cartridge is installed, or if a message indicates a cartridge problem, try removing
the cartridges, verifying the protective piece of plastic tape has been removed from each cartridge, and
then reinserting the cartridges. If this does not work, clean the cartridge contacts. If the problem is still not
resolved, replace the cartridges.
For information about replacing cartridges, see Replace the cartridges .
To clean cartridge contacts
CAUTION: The cleaning procedure should take only a few minutes. Make sure that the cartridges are
reinstalled in the printer as soon as possible. It is not recommended to leave the cartridges outside the
printer longer than 30 minutes. If cartridges are left unprotected outside the printer, their nozzles might dry
out and clog up.
1. Check that power is on.
