Cleaning the Print Head
Clean the Print Head if lines are missing or if white streaks are present in the printed nozzle check
pattern. Cleaning unclogs the nozzles and restores the print head condition. Cleaning the Print Head
consumes ink, so clean the Print Head only when necessary.
You need to prepare: a sheet of A4 or Letter-sized plain paper
Note
If the Inner Cover is open, close it.
