Description
The drum rotates as long as the JOG switch (drum rotation switch) is pressed (within one rotation) and stops
at the stop position with a beep.
When the drum stops there, the LED mounted on the JOG switch 1 will light up.
In the normal state, the drum rotates (within one
rotation) when the JOG switch (drum rotation
switch) is kept pressed and the drum stops at the
stop position, reducing the speed to the slow
(before-stop) speed at the first master removal
position.
When the P-roller sensor is in the photopassing
state (P-roller ON) at the first plate detachment
position, the drum passes the stop position
without reducing the speed.
