When you have performed the procedure until step 4 and the problem has not been resolved, turn off the
power and clean the print head deeply again after 24 hours.

Ink flush consumes a great amount of ink. Frequent ink flush can rapidly consume ink, so perform ink flush
only when necessary.
Important
• If ink flush is performed when the remaining ink level is insufficient, it may cause a failure. Be sure to •
check the remaining ink level before performing ink flush.
