See “Erase lamp removal”. Retest printer. If error clears, problem solved, otherwise remove toner cartridges and photodeveloper cartridge and go to step 3. 3 Set multimeter to check diodes. Looking at erase lamp through front cover, touch meter positive lead to left LED connection and meter negative lead to right LED connection. LED should illuminate. Check all LEDs on erase lamp board. Do any LEDs fail to illuminate? Replace erase lamp. See “Erase lamp removal”. Retest printer. If error clears, problem solved, otherwise go to step 4. Go to step 4. 4 Remove engine controller board board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Is cable properly connected to engine controller board connector MCN8? Go to step 5. Properly connect cable. Retest printer. If error clears, problem solved, otherwise go to step 5. 5 Disconnect cable from erase lamp and engine controller board MCN8. Check for continuity between cable pin that corresponds to MCN8 pin 11 and erase lamp cable connector pin 3. Also check for continuity between cable pin that corresponds to MCN8 pin 12 and erase lamp cable connector pin 1. Check for shorted pins on both sides of cable. Is cable okay? Replace engine controller board. See “Engine controller board removal”. Go to step 6. Replace cable. Retest printer. Go to step 6. 6 Retest printer. Does error clear? Problem solved. Contact higher level support.
Code: SVC F0
Description: Power supply fan error
Causes: Improper fan motor rotation, improper fan motor cable connection or a shorted or cut cable
Remedy: 1 Turn printer off and remove engine controller board board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Is cable properly connected to engine controller board connector MCN10? Go to step 2. Properly connect cable. 2 Ensure rear cover assembly cover is shut. Override top and front cover interlock switches. For location, see “Interlock switch locations”. Reconnect operator panel. Turn printer on and check for 24VDC between engine controller board MCN10 pin 1 and power ground (you can touch negative lead of voltmeter to metal frame to obtain ground.) Is voltage present and correct? Replace power supply fan assembly. See “Power supply fan removal”. Retest printer. If error clears, problem solved, otherwise go to step 3. Go to step 3. 3 Turn printer off and disconnect cable from engine controller board MCN10 and power supply fan. Check cable for continuity and pin shorts. Is cable okay? Replace engine controller board. See “Engine controller board removal”. Replace cable.
Code: SVC F4
Description: Exit fan error
Causes: Improper fan motor rotation, improper fan motor cable connection or a shorted or cut cable.
Remedy: 1 Turn printer off and remove engine controller board board shield. See “Engine controller board removal” for steps to remove engine controller board shield. Is cable properly connected to engine controller board connector MCN1? Go to step 2. Properly connect cable. 2 Ensure rear cover assembly cover is shut. Override top and front cover interlock switches. For location, see “Interlock switch locations”. Reconnect operator panel. Turn printer on and check for 24VDC between engine controller board MCN1 pin 4 and power ground (you can touch negative lead of voltmeter to metal frame to obtain ground.) Is voltage present and correct? Potentially faulty fuser fan. Replace rear cover assembly. See “Rear cover assembly removal”. Retest printer. If error clears, problem solved, else go to step 3. Go to step 3. 3 Turn printer off and disconnect cable from engine controller board MCN1 and power supply fan. Check cable for continuity and pin shorts. Is cable okay? Replace engine controller board. See “Engine controller board removal”. Replace cable.
Code: SVC F5
Description: HV power supply (HVPS) error
Causes: Output (BRV) of HVPS is shorted, and or HVPS cable connector is improperly connected.
Remedy: 1 Remove photodeveloper cartridge and ensure charging unit on bottom of photodeveloper cartridge is not damaged. Is charging unit damaged? Replace photodeveloper cartridge. See “Photodeveloper cartridge removal”. Note: Photo-developer cartridge is a customer ordered part. Go to step 2. 2 Check charging unit high voltage contacts in printer. Are they clean? Go to step 3. Clean contacts. If problem persists, go to step 3. 3 Replace photodeveloper cartridge. See “Photodeveloper cartridge removal”. Has error cleared? Note: Photo-developer cartridge is a customer ordered part. Problem solved. Go to step 4. 4 Check cable for continuity between engine controller board connector HVCN and HVPS BCN1 connector and for shorted pins. Is cable okay? Go to step 5. Replace cable. 5 Replace HVPS. See “High voltage power supply (HVPS) removal”. Has error cleared? Problem solved. Go to step 6. 6 Replace engine controller board. See “Engine controller board removal”. Has error cleared? Problem solved. Contact higher level support.
Code: SVC F6
Description: LV power supply (LVPS) error .
Causes: Data communication error between LVPS and the engine controller board
Remedy: 1 Check cable for continuity between engine controller board connector LVCN and LVPS ACN4 connector. Also check for shorted pins. Is cable okay? Go to step 2. Replace cable. 2 Replace LVPS. See “Low voltage power supply (LVPS) with cage removal”. Does problem persist? Go to step 3. Problem solved. 3 Replace engine controller board. See “Engine controller board removal”. Does problem persist? Contact higher level support. Problem solved.
Code: SVC H0
Description: Fuser thermistor error
Causes: Temperature signal from thermistor is not detected.
Remedy: 1 Check for proper input line voltage. Is line voltage correct? Go to step 2. Provide proper line voltage. 2 Remove and reinstall fuser assembly. See “Fuser assembly removal”. Does error clear? Problem solved. Go to step 3. 3 Check fuser connector for damage. Replace if necessary. Does error clear? Problem solved. Go to step 4. Turn printer off and check cable that connects engine controller board connector FUCN to fuser for proper connection, continuity, and pin shorts. Is cable okay? Go to step 5. Properly connect cable or replace if damaged. If error clears, problem solved, otherwise go to step 5. 5 Replace fuser assembly. See “Fuser assembly removal”. Does error clear? Note: Fuser is a customer ordered supply. Problem solved. Replace LVPS. See “Low voltage power supply (LVPS) with cage removal”. If error does not clear, replace engine controller board. See “Engine controller board removal”.
