54 Routine Maintenance
Print Head Cleaning
Clean the Print Head if lines are missing or if white streaks appear in the printed nozzle check
pattern. Cleaning unclogs the nozzles and restores the print head condition. Note that cleaning the
Print Head causes used ink to be absorbed in the ink absorber. Cleaning the Print Head consumes
ink, so perform Print Head Cleaning only when necessary.
1 Make sure that the machine is turned on, open the Front Tray, and extend the
Output Paper Support.
2 Load a sheet of A4 or Letter-sized plain paper in the Rear Tray or Front Tray.
3 Press the Paper Feed Switch to select the paper source where you have loaded
paper.
