Checking the Print Head Nozzles
If you find that the printout is unexpectedly faint or that dots are missing, you may be able to
identify the problem by checking the print head nozzles.
You can check the print head nozzles from your computer by using the Nozzle Check utility or
from the printer by using the control panel or buttons.
Note:
This printer checks the print head on a regular basis to keep the print head clean and to ensure you receive
premium print quality. If the print head nozzles are clogged, the printer automatically cleans the print head.
Normally, you do not need to perform the nozzle check and print head cleaning, however, the self-cleaning
function cannot completely prevent the occurrence of missing dots.
