E014-0001-05 Fixing Motor error
Detection Description It did not become the specified speed for 500 consecutive msec although 1000 msec have passed
from the startup of the Fixing Motor. (The detection timing varies depending on the paper feed
conditions.)
Remedy
[Related parts] R1.00
- Harness between the DC Controller PCB (UN04/J135) and the Fixing Motor (M04/J5412)
- Fuse in the DC Controller PCB (UN04/FU1)
- Fixing Motor (M04)
- Idler Gear in the Fixing Assembly
- Pressure Roller Gear in the Fixing Assembly
- Fixing Assembly
- DC Controller PCB (UN04)
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check that the Fixing Assembly is pushed into the host machine so the handle is locked and
there is no backlash while it is installed.
2. Remove the Fixing Assembly, and rotate the Idler Gear and the Pressure Roller Gear by hand
to check visually that there is no bent or missing teeth or abnormal abrasion (edge of the gear is
no longer tooth-shaped).
3. Replace the Fixing Assembly.
4. Check the harness between the DC Controller PCB and the Fixing Motor.
5. Measure the both ends of the fuse in the DC Controller PCB using a tester.
a. If the measurement value is less than 1 ohm (conduction state),
1. Replace the Fixing Motor.
2. Replace the DC Controller PCB.
b. If the measurement value is 1 ohm or higher (non conduction state), replace the DC Controller
PCB.
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.

E014-0002-05 Fixing Motor error
Detection Description The specified speed could not be detected for 500 consecutive msec although it became the
specified speed at least once from the startup of the Fixing Motor. (The detection timing varies
depending on the paper feed conditions.)
