| Relevant electrical parts | • Fusing unitIH coil (IHC) • IH power supply (IHPU) • NF board (NFB) • MFP board (MFPB) |
Procedure
- Check the fusing unit for correct installation (whether it is secured in position).
- Check the fusing unit-MFPB CN22E for proper connection and correct or change as necessary.
- Check the connector between NFB CN2-IHPU CN1 for proper connection and correct as necessary.
- Check the connector between IHPU CN8-MFPB CN3E for proper connection and correct as necessary.
- Check the marketing area of the fusing unit. If the marketing area is incorrect, replace the fusing unit for proper marketing area.
- Check the marketing area of IHPU. If the marketing area is incorrect, replace IHPU for proper marketing area.
- Replace IHC. (Part# A79JM40C00)
- Replace IHPU. (Part# A8KNM40A02)
- Replace MFPB. (C458 Part# A79MH02102 / C558 or C658 Part # A79JH02102)
- Replace NFB. (Part# A795M40J00)
