Canon B115, B140, B120 manual Replacing the BJ cartridge, Cleaning the BJ cartridge print head

K 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 (see p. 9-5). If the pattern is broken or missing, clean the BJ cartridge print head.

• To maintain the best possible print quality, clean the BJ cartridge print head from time to time.

• Cleaning the print head consumes a small amount of ink. Cleaning too often reduces the amount of ink
