Position Description 3 Front tamper offset position 4 Rear tamper home position-sensor (rear tamper HP) 5 Rear tamper size position 6 Rear tamper offset position Center tamping Center tamping is used when executing rear stapling (straight). The tamper positions during center tamping are shown below.

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. Diagnostic aids 3-87
