Checking the Print Head Nozzles

Using the Nozzle Check utility
Using the control panel buttons

If you find that the printed image is unexpectedly faint or dots in the printed image 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 with the Nozzle Check utility in the printer software, or from the printer itself by using the printer's control panel buttons.

Do not use the Nozzle Check utility while printing is in progress; otherwise your printout may be marred.

Using the control panel buttons

Make sure that A4 or Letter size paper is loaded in the sheet feeder.

Hold down the load/eject button and press the power button to turn on the printer. 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

Print head needs to be cleaned

If the nozzle check page does not print satisfactorily (for example, if any segment of the printed lines is missing) there is a problem with the printer. This could be a clogged ink nozzle or a misaligned print head. See Cleaning the Print Head for details on cleaning the print head. For information on aligning the print head, see Aligning the Print Head.
