 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 solve these problems 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.

The printer prints an operation check page including your printer's ROM version information, the ink counter code, and a nozzle check pattern. Here is a typical printout:
Good sample
Print head needs to be cleaned
The above sample is in black and white, but the actual test prints in color (CMYKcm).

Press the power button to turn off the printer after it finishes printing the nozzle check pattern.
|
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.
