Setup Cartridges
When you first setup the printer, you must install the cartridges that shipped in the box with the printer. These
cartridges are labeled SETUP, and they calibrate your printer before the first print job. Failure to install the
SETUP cartridges during the initial product setup causes an error. If you installed a set of regular cartridges,
remove them and install the SETUP cartridges to complete printer setup. After printer setup is complete, the
printer can use regular cartridges.
WARNING! Don’t open or uncap cartridges until you are ready to install them. Leaving caps on the
cartridges reduces ink evaporation. You can use the orange caps from the SETUP cartridges if necessary.
