3-6
Cause Point to check Action
C1 Check the tube to see if it is filled with ink, and also check the joint. T11 (P4-15)
C3 Check to see if the carriage encoder is properly installed. T13 (P4-19)
C3 Check the carriage encoder for defects (such as soiling, flaws and incorrect setup). T01 (P4-1)
C2 Check to see if there is not any foreign matter near the head management sensor. Remove.
C1
Check service mode nozzle patterns (upgrade to Ver.1.23 from any earlier release before
making this check)
Flow 1
C3 Check the firmware (Countermeasure for non-ejection detection position)
Upgrade to
the latest
version
C1 Check to see if the ink is a genuine supply. (Recommend the use of the genuine ink.)
