Code C0F36 is a low toner density error on the black developing unit.

Was it asking for black toner before this code appeared?

SOURCE: Konica 7145 F-51-2 Error

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!!!

(2) While pressing the numerical keys 2 and 5 of the copy
quantity setting button, turn the main switch ON. This
