No. Description/Definition Points to Check
E-00 Clamper Motor Failure
The MPU cannot detect the master
clamper position sensor signal (open or
closed) within 1.2 seconds after the
clamper motor turns on.

E-01 Cutter Failure
•
The cutter HP sensor does not turn on
within 3 seconds after the cutter motor
turns on.
•
If the master is not cut at the end of the
master making. The drum master
detection sensor is used to check if the
black cover at the trailing part of the
drum cloth screen is covered by the
master just before the drum returns the
home position. In this case, the SC is
cleared once the power is off.
