Description: Pre-transfer Charging Shutter HP close error.
The Pre-transfer Charging Shutter Sensor (PS95) detects that the shutter is closed although it is moved to the open position.
Remedy: 1. Check the position of the Pre-transfer Charging Shutter. 1-A. In the case that the Pre-transfer Charging Shutter fails to operate (stopped at HP at front side) Check the connection of the Pre-transfer Charging Wire Cleaning Motor (M7). Sensor side: J3108, J3089 (relay), PCB side: J3088 (relay), J114 (Main Driver PCB (PCB2)) 1-B. In the case that the Pre-transfer Charging Shutter is stopped at rear side (close operation position) 1-B-1. Check that the Primary Fan Duct is closed. Close the Primary Fan Duct. 1-B-2. Check movement of the pin to push the Pre-transfer Charging Shutter Sensor (PS95). Replace the Pin. 1-B-3. Check movement of the flag on the Pre-transfer Charging Shutter Sensor (PS95). Replace the flag/ spring. 1-B-4. Check the connection of the Pre-transfer Charging Shutter Sensor (PS95). Sensor side: J2114, J3215 (relay), J3067 (relay) PCB side: J3066 (relay), J130 (Main Driver PCB (PCB2)) 1-C. In the case that the Pre-transfer Charging Shutter is stopped along the way 1-C-1. Check abrasion of the Slider Pin. Replace the Slider Pin. 1-C-2. Replace the Pre-transfer Charging Assembly. 2. Replace the DC Controller PCB (PCB1).
