Clean the printhead
Complete the printhead cleaning procedure. For more information, see To clean the
printheads. The printhead may need to be cleaned if the printer was turned off
incorrectly.
NOTE: Incorrectly turning off the printer can cause print quality problems like
blank or partial pages. Printhead cleaning can solve these problems, but turning off
the printer correctly can prevent them in the first place. Always turn the printer off
by pressing the Power button on the printer. Wait until the Power light goes out
before unplugging the power cord or turning off a power strip.
Check the media settings
• Make sure you select the correct print quality settings in the printer driver for the
media loaded in the trays.

loaded in the tray.

see Understand the Self Test Diagnostic Page.
