28 Routine Maintenance
Examining the Nozzle Check Pattern
Examine the nozzle check pattern, and perform cleaning if necessary.
1
Check the nozzle check pattern you printed.
(1) If lines of this pattern are missing, the print head nozzles need cleaning.
Example: When lines are missing (Black ink)
(2) If these patterns have white streaks, the print head nozzles need cleaning.
Example: When white streaks appear (Color ink)
2
When cleaning is necessary, perform Print Head Cleaning.
See “Print Head Cleaning” on page 29.
Note
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 33.
