M1 error on Konica Bizhub series

The following is a description of the M1 process on the Bizhub

M1 (main) is controlled by the PRCB (printer control
board) and the motor drive power is supplied from
DCPS2 (DC power supply unit 2).

1. Operation

M1 is a motor driven by 24V DC. It drives fixing
upper and lower rollers, paper conveyance belts,
and thick paper conveyance roller. M1 incorporates
a speed controller circuit to send a signal
indicating abnormal rotation to PRCB when the
PLL lock has been released for longer than the
specified period of time.
M1 starts rotating when the START PRINT button
is pressed and stops when the last copied
paper has been ejected. During the warm-up
operation, M1 rotates to rotate the fixing rollers.
When either one of the front doors of this machine
opens or closes, MS1 (interlock 1) or MS2
(interlock 2) actuates to stop supplying the DC
power to the motor, causing the M1 to stop.

2. Signals

a. Input signal

(1) M1 EM (M1 to PRCB)
M1 fault detection signal
[H]: Abnormal rotation (PLL lock has been
released for 2 to 3 seconds or longer.)
[L]: Normal rotation

b. Output signal

(1) M1 CONT (PRCB to M1)
M1 drive control signal.
[H]: M1 ON
[L]: M1 OFF

Hope this gives some help

good Luck
