Code: C2255, C2256
Description:
• C2255: Developing motor/YMC failure to turn • C2256: Developing motor/YMC turning at abnormal timing
• C2255: The motor lock signal remains HIGH for a predetermined continuous period of time while the motor is turning. • C2256: The motor lock signal remains LOW for a predetermined continuous period of time while the motor remains stationary.
Causes:
• Imaging unit/C • Imaging unit/M • Imaging unit/Y • Developing motor/YMC (M17) • MFP board (MFPB)
Remedy:
1. Check the connector between M17-MFPB CN10E, CN16E for proper connection and correct as necessary. 2. Check the connector of M17 for proper drive coupling and correct as necessary. 3. M17 load check • Check code: 50 • Multi code: 2, 3, 4 • Control signal: MFPB CN16E-1 (DC24V), MFPB CN10E-9 (START/STOP) • Location of electrical component: 6-K 4. Replace M17. 5. Replace the imaging unit/Y,M,C. 6. MFPB F9E conduction check 7. Replace MFPB.
