Title
Toner container sealing/release holder shift cam HP
sensor timeout (Bk) error
Description
of detection
HP sensor of release holder shift cam cannot detect
within specified period of time.
Measures
1. Check the connection of the toner container drive
motor (M7) harness. (Check whether the wire is not
caught by parts.) Check the connection with the
hopper driver PCB.
Motor side: J7107, J8041 PCB side: J1370
2. Check the connection between the release holder shift
cam HP sensor (PS8) and the hopper driver PCB.
Sensor side: J7139, J8040 PCB side: J1340
3. Clean and replace the toner feed screw rotation
sensor.
4. Replace the hopper/stirring supply motor.
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>

Title
Toner container/toner container inserting inlet phase (Bk)
error
Description
of detection
When the power was turned on, it was detected that the
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 (PS7) and the
hopper driver PCB. (Connection of the connector,
Shorting, Wire caught by parts)
Sensor side: J7138, 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, Shorting, Wire caught by
parts)
Sensor side: J7154, J8041 PCB side: J1370
4. Replace the toner container inserting inlet cover open/
close sensor.

Title
Error in Bk Toner Container Reciprocation HP Sensor
(PS8)
Description
of detection
Unable to detect the change in the Release Holder Shift
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
soiled and the installation of the sensor.
2. Drive the Hopper Unit a little with the Toner Container
Removing Tool, and check the service mode (COPIER>
I/O> DC-CON> P052 bit12) 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.
3. If the problem is not solved by replacing the foregoing
parts, replace the Hopper Driver PCB (UN3) and then
perform step 4 and later steps.
4. Clear the error in service mode (COPIER>
FUNCTION> CLEAR> ERR), and then turn OFF and
then ON the main power.
5. Replace the toner (reinstall the removed Toner
Container) at least once in user mode (Adjustment/
Maintenance> Replace Specified Toner), and check
that toner replacement can be performed normally.
