Whenever you turn off the printer, 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.
