6.6.6 DETECTION OF MASTERS ON THE DRUM

[A]: Drum master sensor

[B]: Black patch on the screen

[C]: Black patch on the clamper

• The drum master sensor [A] detects whether there is a master on the drum.

• When there is a master on the drum, the black patch [B] is covered and the

sensor detects the light reflected from the master. When there is no master on

the drum, the black patch [B] is exposed. The black patch does not reflect light

back to the sensor. Because of this, the master eject process can be skipped

when a new master is being made, if no master is detected on the drum.
