Cleaning the Print Heads
After deep print head cleaning, print and examine the nozzle check pattern: Step1
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. Do not unplug the power cord when turning off the
power.
If the problem is still not resolved, perform ink flush.
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.
