E025 -0210 -05 Title Toner container sealing/release holder shift cam HP
sensor timeout (M) error
Description HP sensor of release holder shift cam cannot detect
of detection within specified period of time.
Measures 1. Check the connection of the toner container drive
motor (M13) harness. (Check whether the wire is
not caught by parts.) Check the connection with the
hopper driver PCB.
Motor side: J7105 PCB side: J1370
2. Check the connection between the release holder shift
cam HP sensor (PS14) and the hopper driver PCB.
Sensor side: J7126, J8107 PCB side: J1350
3. Replace the toner container drive motor.
4. Clean and replace the release holder shift cam HP
sensor.
5. Replace the hopper unit.
CAUTION:
As for Remedy 5, since it is difficult to identify the cause,
it is recommended to replace the unit.
NOTE: After performing the above remedy work, go
through the following to clear the error: COPIER>

E025 -0220 -05 Title Toner container/toner container inserting inlet phase (M)
error
Description When the power was turned on, it was detected that the
of detection toner container cap was opened (the release holder shift
cam phase sensor was protected against light) AND the
toner container inserting inlet cover was opened (the
toner container inserting inlet cover open/close sensor
was transmissive).
Measures 1. Close the toner container inserting inlet cover and turn
OFF/ON the power.
2. Check the connection between the toner container
inserting inlet cover open/close sensor (PS13) and
the hopper driver PCB. (Connection of the connector,
Breaking, Wire caught by parts)
Sensor side: J7125, J8115 PCB side: J1360
3. Check the connection between the release holder shift
cam phase sensor (PS82) and the hopper driver PCB.
(Connection of the connector, Breaking, Wire caught
by parts)
Sensor side: J7151 PCB side: J1390
4. Replace the toner container inserting inlet cover open/
close sensor.

(PS14)
Description Unable to detect the change in the Release Holder Shift
of detection Cam HP Sensor status (ON -> OFF) when opening the
cap so that open and close status of the cap cannot be
judged.
Measures Identify the cause of the error whether it is due to
mechanical problem to open/close the cap or problem at
the Release Holder Shift Cam HP Sensor side.
1. Check if the Release Holder Shift Cam HP Sensor is

Removing Tool, and check the service mode (COPIER>
I/O> DC-CON> P052 bit14) to see that the output
value of the sensor is changed.
Since it is difficult to check the screen while driving it,
repeat the operation to drive it a little and check the
screen until the value is changed.
If it is normal, the output value of the sensor is
changed when opening/closing the cap. Even if it is
normal, be sure to perform step 4 and later steps.
2-1. If there is an error in drive of the Hopper Unit,
check the drive system such as gears.
If it is damaged, replace the Set-on Drive Unit
and then perform step 4 and later steps.
2-2. When the output value of the sensor is not
changed although the Hopper Unit is driven,
check the Sensor Harness (to see if the harness
is caught, disconnected or physically removed).
If there is no problem, replace the sensor. After
checking the output value in step 2, perform step
4 and later steps.
