[Error Code] Ricoh Pro C9110 SC590-09 and SC441-51

[sniper2g8]

I have been battling with SC590-09, these error mostly happens when there is a paper jam in either of the two units, so I decided to check the harness of the transport motor 4 by opening the Engine back, after checking the fitment of the cables and making sure all the connectors are connected properly, I turn on the machine and now I have SC441-51. I have lost ideas and don't know what to do again please help me. I have the service manual. thanks in advance

Hi, are you sure about the error subcode, before going to check the connections on the board what did you check first? Have you checked if there are jam codes and in the history codes?

The error code is SC590-09 it will only appears when there's paper jammed in either the fusing section or in the imaging section and it will always display system malfunction press restart. Ive change the relay on the IOB2 board but still the same. Kindly help me
