Center tamping
Center tamping is used when executing rear stapling (straight).
The tamper positions during center tamping are shown below.
Determining tamper home position
When the sensor (lower media exit) turns high (+5 V dc) (light receiving), the front and rear tamper motors on
the compiler unit assembly are activated, and the front and rear tampers start moving.
The front tamper home position is determined when the front tamper enters the sensor (front tamper HP)
sensing area.
In the same way, the rear tamper home position is determined when the rear tamper enters the sensor (rear
tamper HP) sensing area.
Tamping
Tamping is executed after a preset time has passed after the sensor (compiler media present) turns high
(+5 V dc) when media is detected on the compiler unit assembly.
