Konica 7075 - SC : F42-04 - F46-25

mmmm, I think you disassembled without knowledge, or to an error when connecting harness again.
Well...! contact Technical Service that may guide.. or follow the recommendations.

---------------------------------------------------------------------------------
F42-04 - Check on FM5 (write section cooling 1) rotation and 24 V power supply.
The FM5 EM signal was abnormal at specified time after turning ON of FM5/8 (write section cooling 1/2). At specified time after turning FM5/8 OFF and ON again, the FM5 EM signal is still abnormal and an abnormal detection signal (24 V off) is detected.

FM8 (write section cooling 2)

first thank you very much for your great help,
if not familiar with this machine and take it apart, but the reassembly forget to connect the party with three peaks is close to the drum and then I made a copy, and there fans the back started very quickly and I It Works came these two errors.

I really need help because I have no idea how to fix and service the company which purchased the machine tells me this holiday and will return within 1 month.

would be very grateful if you gave me the service manual, thank you very much anyway.

ah I forgot, sorry for my bad English im from south america
