Code :

Code: 10
Description: MF dial is possible but not DP dial.
Causes: • Check DP control signal of CN20-11 of MAIN PBA and the circuit around R15. U6 and Q2 of LIU PBA.
Remedy: • Replace LIU PBA.

Code: 11
Description: Defective FAX transmission
Causes: • Check CN20 (main PBA), main LIU harness, and CN1(LIU PBA). • Is the external phone off the hook? • Check ‘hook off’: Refer to ‘TEL LINE CANNOT BE ENGAGED’ above. • Check the control signals of CN20-11. • Check transmission path: Check output of CN20-3.4 and T2-4(LIU PBA). • Check reception path: Check output CN1-1 (LIU PBA) and input of CN20-1(main PBA).
Remedy: • Replace defective parts. • Replace LIU PBA if low. • Refer to ‘TEL LINE CANNOT BE ENGAGED’ above. • Replace main PBA, if the signals of CN8-11 (MAIN PBA) is low. • Replace main PBA, if abnormal. • Replace LIU PBA if CN1-1(LIU PBA) is not confirmed. Replace main PBA if CN20- 1(MAIN PBA) is not confirmed.

Code: 12
Description: Defective automatic FAX reception
Causes: • Is the ring checked? Check ring pattern at CN1-9 (LIU PBA). • Refer to ‘Defective FAX Transmission.’
Remedy: • Replace LIU PBA if it cannot be checked. • Refer to ‘Defective FAX Transmission’.

Code: 14
Description: Vertical white line.
Causes: 1. LSU window contamination. 2. Toner cartridge.
Remedy: 1. Clean LSU window. 2. If not LSU contamination, install a new toner cartridge.

Code: 15
Description: No image.
Causes: 1. Has the seal tape been removed? 2. Is the GND OPC well grounded? 3. LSU running well? 4. Is the bias voltage normal? 5. Low toner? 6. Is there video data from Main PBA
Remedy: 1. Remove the seal tape. 2. Measure the resistance between. frame ground and the ground spring attached to the frame. If necessary clean the components to achieve a good earth. 3. Adjust LSU or install a new LSI. 4. Normal Dev bias = -350V. 5. If necessary install a new toner cartridge. 6. Test engine test pattern, if necessary, install a new Main PBA

Code: 16
Description: Light image.
Causes: 1. Has the seal tape been removed? 2. LSU light power normal? 3. Enough toner? 4. High charger voltage? 5. Lower bias voltage 6. Contamination of high voltage contact 7. Transfer voltage and roller.
Remedy: 1. Remove the seal tape 2. LSU light power check is difficult. Compare with new one and check. 3. Check toner and developer counter 4 and 5. Check all high voltage outputs 6. Leakage of toner cause bad contacts and increases contact resistance. Clean the contaminated area.
