Replace the printhead
TIP:
When the printhead has been replaced, the printer will automatically perform a printhead
alignment on the loaded paper. If you would like to perform the printhead alignment on a different
paper (perhaps from the multi-sheet tray), you could change the paper before starting this procedure.
Plain white paper is recommended.
1.
Make sure the printer is turned on.
2.
If your printer is on a stand, make sure the printer wheels are locked (the brake lever is pressed
down) to prevent the printer from moving.
3.
From the front panel, press , then Image quality maintenance > Replace printhead.
4.
Open the ink cartridge cover.
5.
