Konica 7145 F-51-2 Error




By wolf9545 on Oct 29, 2008

" "
I have a Konica 7145 copy machine that is producing an error of F-51-2 when I turn the unit on. I had a tech come out and told me that the control board is the problem. I replaced it with a known good board but I am still getting the error.

- Thank you for the help. Sorry it took me so long to give a reply; I actually lost the email and had to dig it up again. I did the test and didn't hear the the motor turn. Ordered a replacement motor but now trying to figure out how to get the old one out. The reason I didn't rate your answer a full one is because even if I replace the motor there is a chance it may not fix it. Thanks again for the help.

- Well, found out how to replace it and replaced the motor. Tried running the code again and didn't hear the motor turn (little hard to see it). Still get the error when I turn the machine on. I have already replaced the big board that sits right in front of the fixing motor (was told by a copy machine tech that it was that problem, something to do with a fuse) so I don't know what else to try. Is there a code to have the machine reset the codes and do a search again?

Code F51-2 at start-up.
Description:
Code F51-2 at start-up.
Solution:
CAUSE: Code F51-2 may be caused by a failed M11 fixing motor. To determine whether or not the motor has failed, use this procedure:
1. Enter the 47 mode (I/O check mode).
2. Input "40".
3. Input multicode "0". If the M11 motor turns, it is good; if it does not turn, the motor has failed.

SOLUTION: Replace the M11 motor (p/n 56AA80072 for 7222/7228/7235 and p/n 56GA73430 for 7145) if it has failed.

hope that help!!!
