SOLUTIONS TO COMMON PROBLEMS
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.
