Whenever the printer stops printing, the BJ cartridge moves to the home
position on the right and caps itself. If you unplug the printer while it is
printing (or if you turn off a power strip to which the printer is
connected), or if you manually move the cartridge holder from the
home position, the BJ cartridge will not be capped and it may dry out.
If you installed a new BJ cartridge, the printer automatically cleans the
print head. If you need to initiate the print head cleaning, see page 4-6.
Replacing a BJ Tank in the BC-21e
Color BJ Cartridge
If you perform a print operation correctly but the output is blank, a
BJ tank may be out of ink. Perform the print head cleaning at least
three times and then print a Nozzle Check Pattern. If the Nozzle Check
Pattern indicates an empty BJ tank, replace the empty BJ tank in the
BC-21e Color BJ Cartridge.
Leave the BJ cartridge in the printer when replacing a BJ tank. Make sure
the printer is plugged in.
