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.
Printing the Nozzle Check
Before cleaning the print head, you may want to print the nozzle check to test the
BJ cartridge installed in the MultiPASS. This test shows if each print head nozzle is
operating properly.
Follow this procedure to print the nozzle check:
1. Press Function.
2. Press Cleaning.
3. Press Set.
❑ The MultiPASS prints the nozzle check.
When the BC-21e Color BJ Cartridge is installed, the pattern includes all four
colors; yellow, magenta, cyan, and black. In the color pattern, you will notice that
lines are missing between the colors. This is normal.
The following sample shows the nozzle check when the optional BC-20 Black
BJ Cartridge is installed:
