Checking the Print Head Nozzles
If you find that the printed image is unexpectedly faint or dots are missing from it,
you may be able to identify the problem by checking the print head nozzles.
You can check the print head
nozzles by using the printer's control panel buttons.
 |
Make sure paper is loaded in the sheet feeder and the printer is turned off. |
 |
Hold down the  load/eject button and press the  power button to turn on the printer. Continue to hold
down the  load/eject for at least 5 seconds, then
release both buttons. |
The printer prints an operation check page including your printer's ROM version
information, the ink counter code, and a nozzle check pattern. Here are sample printouts:
 |
Good sample; all print head nozzles are clean |
|
Bad sample; print head needs to be cleaned |
If any segment of the printed lines is missing, there is a problem with the printer;
most likely a clogged ink nozzle, or a damaged print head or bad ink cartridge. See Cleaning the Print Head for details on cleaning the print
head. If you need to replace an ink cartridge to solve the problem, see Replacing an Old or Damaged Ink Cartridge.
