Replacing a BJ Tank in the BC-21e Color
BJ Cartridge
If you perform a print operation correctly but the output is blank,
portions are missing, or colors are very wrong, a BJ tank may be out
of ink. If the output is still blank after cleaning the print head at least
five consecutive times, replace the empty BJ tank in the BC-21e Color
BJ cartridge.
You leave the BJ cartridge in the MultiPASS when replacing a BJ tank.
The cartridge holder then moves to the
center of the unit.
❍ Grasp both sides and lift it up.

several times, unplug the MultiPASS and let it cool for several minutes.

overheating.) After allowing it to cool, plug the unit in again and press
the
