Error Name/Error Condition/Major Cause/Solution
Image transfer encoder error/Image transfer unit set fault
During encoder count of the transfer motor, if there is no
effective edge interrupt for 1.5 sec, and there is an overflow for
1.5 seconds consecutively, it is determined that there is an
encoder error, SC443-00 is logged, and the system shifts to FG
control without stopping the transfer motor.
This error does not occur in this machine, because it does not
have an encoder.
