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 fax 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 fax. This test shows if each print head nozzle is
operating properly.
