Code: C2259, C225A
Description:
• C2259: Developing motor/K failure to turn • C225A: Developing motor/K turning at abnormal timing
• C2259: The motor lock signal remains HIGH for a predetermined continuous period of time while the motor is turning. • C225A: The motor lock signal remains LOW for a predetermined continuous period of time while the motor remains stationary.
Causes:
• Developing unit/K • Developing motor/K (M19) • MFP board (MFPB)
Remedy:
1. Check the connector between M19-MFPB CN10E, CN16E for proper connection and correct as necessary. 2. Check the connector of M19 for proper drive coupling and correct as necessary. 3. M19 load check • Check code: 50 • Multi code: 5, 6, 7, 8 • Control signal: MFPB CN16E-5 (DC24V), MFPB CN10E-9 (START/STOP) • Location of electrical component: 5-K 4. Replace M19. 5. Replace the developing unit/K. 6. MFPB F10E conduction check 7. Replace MFPB.
