5058-030 Offsetting Offsetting is an operation to shift the position of media to be ejected to the stacker media bin so that boundaries between media units (sets of media, job units, etc.) can be easily recognized. Offsetting is executed for staple positions: • During front stapling (corner)-Shifts stapled sheets using the front tamper by 20 mm to the rear side before ejecting them to the stacker media bin • During rear stapling (corner/straight) - For media with a width of 216 mm or more [rear staple (corner)]-Shifts stapled sheets using the rear tamper by 20 mm to the front side before ejecting them to the stacker media bin - For media with a width of less than 216 mm [rear staple (straight)]-Shifts stapled sheets using the front tamper by 9 mm to the rear side before ejecting them to the stacker media bin. During dual stapling: • Shifts stapled sheets using the front tamper by 9 mm to the rear side before ejecting them to the stacker media bin. • Offsetting is not executed (0 mm) for small media. Functions of compiler unit assembly sensors/motors • Sensor (compiler media in) - A photo-interrupter sensor that detects whether media is present or not on the compiler unit assembly. - When media is detected, the actuator leaves the sensing area, which turns the sensor to high (+5 V dc) (light receiving). • Sensor (front tamper HP) - A photo-interrupter sensor that detects the front tamper home position. - When the front tamper comes to the home position, it enters the sensor's sensing area, which turns the sensor to high (+5 V dc) (light blocking). • Sensor (rear tamper HP) - A photo-interrupter sensor that detects the rear tamper home position. - When the rear tamper comes to the home position, it enters the sensor's sensing area, which turns the sensor to high (+5 V dc) (light blocking).
