1. Load A4-size plain paper in the printer.

   Loading Paper in the Paper Cassette

2. Select System Preferences from the Apple menu > Printers & Scanners (or Print & Scan, Print & Fax), and then select the printer.

3. Click Options & Supplies > Utility > Open Printer Utility.

4. Click Nozzle Check.

5. Follow the on-screen instructions.

   Important:

   If print quality has not improved after repeating nozzle check and head cleaning 3 times, wait for at least 12 hours without printing, and then run the nozzle check again and repeat the head cleaning if necessary. We recommend turning off the printer using the button. If print quality has still not improved, run Power Cleaning.
