Testing And Cleaning The Bj Cartridge Print Head; Printing The Nozzle Check Pattern - Canon MultiPASS C755 User Manual

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 Pattern

Before cleaning the print head, you may want to print the nozzle check pattern to test
the print head of the BJ cartridge installed in the MultiPASS. This test shows if each
print head nozzle is operating properly.
Refer to the flow chart (1 p. 12-8) for the correct order of testing and cleaning the BJ
cartridge print head.
Follow this procedure to print the nozzle check pattern:
