Causes:
• Fusing unit • IH coil (IHC) • IH power supply unit (IHPU) • Noise filter (NF1) • MFP board (MFPB)
Remedy:
1. Check the fusing unit for correct installation (whether it is secured in position). 2. Check the marketing area of the fusing unit. If the marketing area is incorrect, replace the fusing unit for proper marketing area. 3. Check the marketing area of IHPU. If the marketing area is incorrect, replace IHPU for proper marketing area. 4. Check the connector between IHPU-IHC for proper connection and correct as necessary. 5. Replace IHC. 6. Replace IHPU. 7. Replace NF1. 8. Replace MFPB.
