Blank or partial page printed
Clean the printhead
Complete the printhead cleaning procedure. 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) button
light goes out before unplugging the power cord or turning off a power strip.
