Checking the Print Head Nozzles

Using the Nozzle Check utility
Using the control panel buttons

If you find that your printouts and copies are unexpectedly faint or that there are gaps (missing dots) in the printed image, you may be able to identify the problem by checking the print head nozzles.

You can check the print head nozzles from your computer or from the control panel. To check from your computer, use the Nozzle Check utility in the printer software window. Both methods are described below.

Using the Nozzle Check utility

Note:

Do not start the Nozzle Check utility while printing is in progress. Doing so may mar your printout.

Access the printer software window. If you need instructions, see Accessing the printer software.

Click the Utility tab in the printer window, then click the Nozzle Check button.

Follow the messages on your screen.

For Macintosh users

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

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

If the Stylus Scan is on, press the power button once to turn it off.

Print head needs to be cleaned

If the quality is not satisfactory (for example, if a line segment is missing), it is likely that a nozzle is clogged or that the print head is out of alignment. For information about how to clean the print head, see the next section. For information about how to realign the print head, see Aligning the Print Head.
