Causes: Unstable transfer belt rotation—color matching cannot be secured.
Remedy: 1 Open rear cover assembly and check transfer belt unit markers for stains. Are markers stained? Clean belt marker area with cotton cloth. If problem persists go to step 2. Go to step 2. 2 Remove transfer belt unit and observe markers on side. Are belt markers deformed or does transfer belt seem hard to rotate? Replace transfer belt unit. See “Transfer belt unit removal”. Reinstall transfer belt unit. Go to step 3. 3 Turn printer off and remove engine controller board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Are cables properly connected to engine controller board connectors MCN9 and POCN? Go to step 4. Properly connect cables. If problem persists, go to step 4. 4 Ensure rear cover assembly and front cover assembly are closed. Override top interlock switch and turn printer on. Wait until printer displays error and remove MCN9 from engine controller board. Check for 5 VDC between MCN9 pin 1 (on engine controller board) and ground (you can touch negative lead of voltmeter to metal frame to obtain ground.) Is voltage present and correct? Engine controller board is providing 5 VDC to marker sensor. Replace transfer belt marker sensor. Marker sensor is part of a bracket assembly. See “Bracket assembly removal”. If problem persists, replace engine controller board. See “Engine controller board removal”. Go to step 5. 5 On engine controller board, reconnect MCN9 and disconnect cable from POCN. On cable disconnected from POCN, check for 5 VDC from pin 13 to ground (you can touch negative lead of voltmeter to metal frame to obtain ground.) Is voltage present and correct? LVPS is providing 5 VDC to engine controller board. Replace faulty engine controller board. See “Engine controller board removal”. Replace LVPS. See “Low voltage power supply (LVPS) with cage removal”.

Remedy: 1 Turn printer off and remove printer right cover. See “Right cover removal”. Is cable properly connected to cleaning roller clutch? Go to step 2. Properly connect cable. If problem persists, go to step 2. 2 Disconnect transfer belt cleaning roller clutch from cable. Measure resistance between two outer pins on cleaning roller clutch. Does resistance measure between 198 and 242 ohms? Go to step 3. Replace faulty cleaning roller clutch. See “Cleaning roller clutch removal”. 3 Remove engine controller board shield. See “Engine controller board removal” for steps to remove shield. Disconnect cable from MCN4 on engine controller board. Check cable continuity from MCN4 pins 1and 2 (cable) to connector that attaches to cleaning roller clutch. Ensure that pins are not shorted. Is cable okay? Replace engine controller board. See “Engine controller board removal”. If problem persists, replace faulty cleaning roller clutch. See “Cleaning roller clutch removal”. Replace cable. If problem persists, replace faulty cleaning roller clutch. See “Cleaning roller clutch removal”.
Code: SVC E7
Description: Pick-up (paper-feed) clutch error .
Causes: Improper paper-feed clutch cable connection or a shorted or cut cable
Remedy: 1 Turn printer off and remove printer right cover. See “Right cover removal”. Is cable properly connected to paper feed clutch? Go to step 2. Properly connect cable. If problem persists, go to step 2 2 Disconnect paper feed clutch from cable. Measure resistance between two outer pins on paper feed clutch. Does resistance measure between (check these values) 119 and 145 ohms? Go to step 3. Replace faulty paper feed clutch. See “Clutch removal”. 3 Remove engine controller board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Disconnect cable from MCN4 on engine controller board. Check cable continuity from MCN4 pins 9 and 10 (cable) to outer pins on connector that attaches to paper feed clutch. Ensure that pins are not shorted. Is cable okay? Replace engine controller board. See “Engine controller board removal”. If problem persists, replace faulty paper feed clutch. See “Clutch removal”. Replace cable. If problem persists, replace faulty paper feed clutch. See “Clutch removal”.
Code: SVC E8
Description: Registration clutch error
Causes: Improper registration clutch cable connection or a shorted or cut cable
Remedy: 1 Turn printer off and remove printer right cover. See “Right cover removal”. Is cable properly connected to registration clutch? Go to step 2. Properly connect cable. If problem persists, go to step 2. 2 Disconnect registration clutch from cable. Measure resistance between two outer pins on paper feed clutch. Does resistance measure between (****check these values) 119 and 145 ohms? Go to step 3. Replace registration clutch. See “Clutch removal”. 3 Remove engine controller board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Disconnect cable from MCN4 on engine controller board. Check cable continuity from MCN4 pins 7 and 8(cable) to outer pins on connector that attaches to registration clutch. Ensure that pins are not shorted. Is cable okay? Replace engine controller board. See “Engine controller board removal”. If problem persists, replace faulty registration clutch. See “Clutch removal”. Replace cable. If problem persists, replace faulty registration clutch. See “Clutch removal”.
Code: SVC E9
Description: OPC marker sensor error
Causes: Marker sensor is not properly detecting mark on OPC belt.
Remedy: 1 Remove photodeveloper cartridge and check for defects. Does photodeveloper appear ok? Go to step 2. Replace photodeveloper cartridge. 2 Observe markers on side. Are belt markers covered with foreign particles? Clean marker area with cotton cloth. If problem persists go to step 3. Go to step 3. 3 Reinstall photodeveloper cartridge. Turn printer off and remove engine controller board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Is cables MCN7 properly connected to engine controller board? Go to step 3. Properly connect cable. If problem persists, go to step 4. 4 Ensure rear cover assembly and front cover assembly are closed. Override top interlock switch and turn printer on. Wait until printer displays error and remove MCN7 from eengine controller board. Check for 5 VDC between MCN7 pin 3 (on engine controller board) and ground (you can touch negative lead of voltmeter to metal frame to obtain ground.) Is voltage present and correct? Engine controller board is providing 5 VDC to OPC sensor. Replace OPC marker sensor. See “Marker sensor assembly removal”. If problem persists, replace engine controller board. See “Engine controller board removal”. Go to step 5. 5 Reconnect MCN7 and disconnect cable from POCN. On disconnected cable, check for 5 VDC on cable pin corresponding to POCN pin 13. You can touch negative lead of voltmeter to metal frame to obtain ground. Is voltage present and correct? LVPS is providing 5 VDC to engine controller board. Replace engine controller board. See “Engine controller board removal”. Go to step 6. 6 Turn printer off. Disconnect cable that connects LVPS ACN1 to engine controller board POCN and check for continuity, shorted pins, or any other cable damage. Is cable ok? Replace LVPS. See “Low voltage power supply (LVPS) with cage removal”. Replace cable.
