Using the printer buttons
Follow the steps below to check the print head nozzles using the printer buttons.
A
Make sure that no lights are indicating errors.
B
Turn off the printer.
C
Make sure that A4-size paper is loaded in the paper cassette.
D
While holding down the I button, press the P button to turn on the printer.
E
When the printer turns on, release both the buttons. The printer prints the nozzle check pattern.
Below are two sample nozzle check patterns.
Compare the quality of the printed check page with the sample shown below. If there are no print quality
problems, such as gaps or missing segments in the test lines, the print head is fine.
If any segment of the printed lines is missing, as shown below, this could mean a clogged ink nozzle or a
misaligned print head.

Cleaning the Print Head
If you find that the print is unexpectedly faint or that dots are missing, you may be able to solve these problems by
cleaning the print head, which ensures that the nozzles are delivering ink properly.
