Testing and Cleaning the BJ Cartridge Print Head
The print head in the BJ cartridge contains nozzles through which ink is propelled onto
the paper. To maintain the best possible print quality, these nozzles need to be cleaned
from time to time. Your MultiPASS is equipped with a print head cleaning function that
does this.

the print head of the BJ cartridge installed in the MultiPASS. This test shows if each
print head nozzle is operating properly.
