Routine Maintenance

Examine the nozzle check pattern output by the printer, and clean the Print Head if necessary.

Confirm the printed nozzle check pattern.

(1) If lines of this pattern are missing, the print head nozzle needs cleaning.

Example: When lines are missing (Black ink)

(2) If these patterns have white streaks, the print head nozzle needs cleaning.

Example: When white streaks appear (Color ink)

The nozzle check pattern will not be printed correctly if there is not enough ink. Replace the FINE 

Cartridge if the remaining amount of ink is insufficient.
See “Replacing a FINE Cartridge” on page 26.
