Epson AcuLaser C1100
- Code: E527
- Description: Deve Home Position Sensor Error
- PWBA MCU could not receive signals output from Rotary Home Position Sensor within the specified time after rotation of Rotary 45 Developer. - Causes: • MOTOR ASSY MAG • SENSOR ROTARY HOME POSI • HARNESS ASSY MAIN • PWBA MCU
- Remedy: 1 Check of FRAME ASSY-ROTARY and MOTOR ASSY MAG attachment Are FRAME ASSY-ROTARY and MOTOR ASSY MAG attached correctly? Go to Step [2]. Re-attach, and go to step [2]. 2 Rotation check of FRAME ASSYROTARY and MOTOR ASSY MAG Do FRAME ASSY-ROTARY and MOTOR ASSY MAG rotate smoothly? Turn by hand to check. Go to Step [3]. Remove any items that hinder rotation. 3 Check of SENSOR ROTARY HOME POSI attachment Is SENSOR ROTARY HOME POSI attached correctly? Go to Step [4]. Re-attach, and go to step [4]. 4 Operation check of SENSOR ROTARY HOME POSI The voltage of P413-7 . P413-6 on PWBA MCU is 0 VDC when FRAME ASSY ROTARY enters the sensing area, and is 5 VDC when it leaves the sensing area? Replace PWBA MCU. Go to Step [5]. 5 5 VDC power supply check to SENSOR ROTARY HOME POSI The voltage of P413-5 . P413-6 on PWBA MCU is 5 VDC? Go to Step [6]. Go to Step [7]. 6 Continuity check of HARNESS ASSY MAIN Disconnect P/J413 from PWBA MCU. Do all of the wiring below have normal continuity? J413-5 . J105-3 J413-6 . J105-2 J413-7 . J105-1 Replace SENSOR ROTARY HOME POSI. Repair broken or shorted part. 7 5 VDC power supply check to PWBA MCU The voltage of J410-3 . J410-4 on PWBA MCU is 5 VDC? Replace PWBA MCU. Go to Step [8]. 8 Continuity check of HARNESS ASSY MAIN Disconnect P/J410 from PWBA MCU and P/ J502 from LV/HVPS. Do all of the wiring below have normal continuity? J410-3 . J502-3 J410-4 . J502-4 Replace LV/ HVPS. Repair broken or shorted part.
