458e Konica

Konica Minolta C258 error C-40A.
Hello, I found in tray 2, the sensor was short-circuited, which led to the interruption of the ICP8E resistor. After eliminating the short circuit, I made a bridge in place of the interrupted resistance ICP8E, the result is that now the copier works perfectly. I hope it helps.

Sorry, I forget to submit the solution which wasn't related to any boards, we replaced MFPB, we tried and tried and we found in the end something crazy 😄 Just remove the tray 1,2 you'll find the holder with the sensor behind the tray out of the position or broken , corrected by replace it if broken or disconnect it until you replace it.. Thanks.

This 458e returned to customer after routine customer, at remote location. 40A1 kicked in. checked this thread, asked customer to pull oout both trays, Tray 2 was culprit... Thanks otherwise it was ahell of job as customer site is too far away.
