The creaser drive makes
an unusual noise.
The creaser drive motor gear-play is
not set correctly.
Adjust the creaser drive motor gear
play
(see Section 4.5.11).
The creaser input/output
rollers make an unusual
noise.
There is a sheet of paper wrapped
around a roller.
Remove the paper from the creaser
module (see Section 4.3.1).
The roller spring pressure is weak. Check the roller tension springs (see
Section 4.10.2.1).
The crease motor does
not start.
There is no power on the dual power
stepper PCB.
Check the power supply to the high
power stepper PCB.
Replace a PSU (see Section 4.12.6) or
(see Section 4.12.7).
The dual stepper PCB is defective. Replace the dual stepper PCB (see
Section 4.12.3).
There is to signal to the dual stepper
PCB.
Check the signal cable connection
between the dual stepper PCB and the
controller PCB.
Replace the controller PCB (see
Section 4.12.2).
The creaser drive motor is defective. Replace the creaser drive motor (see
Section 4.10.10).
A lead-edge sensor is dirty. Clean the edge sensor set (see
Section 4.13.4).
The crease blade-set
cycles constantly.
There is no input from the creaser
position sensor to the controller
PCB.
Check the creaser position sensor
cable connections.
Replace the creaser position sensor
assembly (see Section 4.10.7).
The DynaTilt mechanism
goes out of position.
The DynaTilt home switch is not set
correctly.
Check the DynaTilt home sequence
(see Section 4.5.16).
The is no signal to the low power
stepper PCB.
Check the signal cable connections
between the low power stepper PCB
and the controller PCB.
Replace the controller PCB (see
Section 4.12.2).
There is no power to the
controller PCB.
The 5V/24V PSU is defective. Replace the 5V/24V PSU (see Section
4.12.8).
The MFC shows a
‘Creaser Error 8’
message.
The sheet that fed was skewed too
far.
Check why the sheet was skewed.
One of the pair of lead-edge sensors
in use is blocked.
Remove the blockage (see Section
4.3.1).
One of the pair of lead-edge sensors
in use is dirty.
Clean the edge-sensor set (see
Section 4.13.4).
One of the pair of lead-edge sensors
in use is defective.
Replace the edge-sensor set (see
Section 4.10.6).
The controller PCB is defective. Replace the controller PCB (see
Section 4.12.2).
