6.9.3 MASTER FEED JAM (D JAM LOCATION INDICATOR)
Cutting the master (master not cut)
Jam check timing: When the master is clamped in the clamper and cutting is
taking place.
Check : While the drum is rotating from when the cutter home position sensor
turns on (cutter at home position) until the master eject position sensor
turns on (drum at master eject position). If the drum master sensor detects
a master on the black patch on the clamper, then the D jam indicator lights.
Check : If the CPU cannot detect the master eject position sensor (drum HP)
signal within 5.0 seconds after the main motor turns on by master cut miss,
the cutter tries to cut the master again. The cutter cuts the master the
second time, and the jam indicator lights. If the cutter does not cut the
master the second time, the E-06 (Main Motor error) indicators lights.
Cutting the master (cutter unit problem)
Jam check timing: When the master is clamped in the clamper and cutting is
taking place.
Check: During master cutting, if the cutter HP sensor does not turn on (cutter does
not reach home position) at the desired time. When the cutter motor
reverses to the cutter reach home position, the D jam indicator lights. When
the cutter motor reverses, the cutter does not reach home position, the E-
01 (Cutter error) indicators lights.
