Cleaning The Bj Cartridge Print Head - Canon B740 Manual

Cleaning the BJ Cartridge Print Head

If your printouts become faint or streaked, or if their quality otherwise deteriorates, print
the nozzle check pattern to see if the print head nozzles are operating properly
(1 p. 12-9). If the pattern is broken, missing, or a specific color is not printed, clean the
BJ cartridge print head.
Refer to the flow chart (1 p. 12-8) for the correct order of testing and cleaning the BJ
cartridge print head.
