Causes: Both the Open Sensing Switch and the Close Sensing Switch detect “0” while the Pocket Door is moving.
Remedy: Pocket Door Part Turn off the machine. Rotate the Pocket Door Motor manually. Does the Pocket Door move smoothly? No 1. Check if the Rack Gear is overrun. 2. Check if the Lever of the Swing Plate comes off the Rack Gear. 3. Check if the Warm Gear and the Motor Output Spindle are fixed properly. Pocket Door Switch Turn off the machine, and rotate the Warm Gear manually. Are S19-1 and S19-2 the following status when the Pocket Door is closed? S19-1: OFF S19-2: ON Are S19-1 and S19-2 the following status when the Pocket Door is opened? S19-1: ON S19-2: OFF No Check the wiring between J19 to the Pocket Door Switch. If there is no problem, replace the Pocket Door Switch with the new one. Pocket Door Motor Enter the Service Mode and select the Output Test 2 of the Function Checking Mode. (Refer to the page 8-31.) Does the voltage between the CN104-4 and CN104-5 on the Control PCB (PW10620) change momentarily (within 2 seconds)? <Note> The Polarity of the voltage (0 to 12V) is inverted depending on the condition of the Pocket Door (open/close). No Check the wiring between CN104 and Pocket Door Motor. If there is no problem, replace the Pocket Door Motor or the Control PCB (PW10620) with the new one.

Code: ED
Description: Developer Motor Error
Causes: LD Signal is detected for 1 seconds continuously while the Developer Motor is rotating.
Remedy: Developer Motor Are the connectors connect with the Developer Motor properly? No Connect properly. Control PCB (PW10620) Enter the Service Mode and select the Manual Charging Test of the Function Checking Mode. (Refer to the page 8-24.) 1. Does the voltage between the CN106-4 (+) and CN106-6 (-) on the Control PCB (PW10620) change to about 6V to 0V when the Developer Motor rotates? 2. Is the voltage between CN211-4 (+) and CN211-1 (-) on the Control PCB (PW10620) about 24V during the Ready condition? No Replace the Control PCB (PW10620) with the new one. Developer Motor Motor Control PCB Replace the Developer Motor or the Motor Control PCB with the new one.
Code: EE
