The Print Cartridge light continues to blink for awhile
and then goes off. (You’ll hear the cartridge cradle return to
its home position on the right side of the printer.)
Note: If the Print Cartridge light continues to blink or
if the cradle doesn’t move to the right side of the printer,
take out both cartridges and reinsert them.
When a print cartridge starts to run out of ink, replace it. If
you do not have a replacement, leave the empty print
cartridge in the cradle of the printer. The printer will not
print with only one print cartridge installed.
We recommend you keep spare print cartridges on hand.
When buying print cartridges, check the part numbers
referenced below carefully to make sure you are buying
the right print cartridges for your printer. These print
cartridges have been specifically designed to work with
your printer to produce results that are always clear,
always sharp.
