Checking the Print Head Nozzles
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.
Follow the steps below to check the print head nozzles using the
control panel buttons.
1. Turn off your printer.
2. Make sure that A4 or Letter size paper is loaded in the sheet
feeder.
3. Hold down the b maintenance button (➀ in the illustration
below) and press the P power button (➁ in the illustration
below) to turn on the printer.
4. Release only the P power button. After the nozzle check
starts, then release the b maintenance button.
