If you cannot resolve the nozzle defects after performing the procedures 1 to 4 above, print nozzle
check pattern after 8 hours or more have elapsed. If you still cannot resolve the defect, you need to
replace the print heads. Contact your service representative.
If Ink Mixes or Missing Nozzles Occur Due to Aeration
If the problem corresponds to either of the following, remove air bubbles by using Print Control. By
removing air bubbles, unnecessary ink and air mixed inside the print heads are discharged from the port
for discharging air bubbles located in the carriage.
• If nozzle clogging is not resolved after cleaning the machine and the print heads.
• If ink colors mix inside the print heads or missing nozzles occur due to aeration.
• If nozzle clogging is not resolved after turning on and cleaning the machine that has not been used
for a long period of time.
The included dedicated tool is required to remove air bubbles.
• Be sure to wear gloves and goggles during the work. Otherwise, ink may drip or be scattered.
• If ink or dust adheres to an area surrounding the print heads, clean the area as required to prevent
the printed materials from becoming dirty.
• Do not place any object on the table as the carriage moves there.
• Be careful so that the air bubble ejection tool will not be removed from the port.
• If you discharged unnecessary ink, contact a company that handles industrial waste.
1. Loosen the 4 screws, and then remove the carriage's front cover.

2. Attach the air bubble ejection tool at the maintenance station position.
Make sure that the tank of the air-bubble ejection tool does not contain any ink. If the tool ejects air
bubbles while there is ink in the tank, the tank may become full, resulting in ink overflow.
