Description
Error in M Toner Container Reciprocation HP Sensor
(PS14)
Unable to detect the change in the Release Holder Shift
Cam HP Sensor status (OFF -> ON) when closing the
cap so that open and close status of the cap cannot be
judged.
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 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.
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.

E025 -02C0 -05 Title Error in M Toner Insertion Inlet Cover Sensor (PS13)
Description Unable to detect opening of the Toner Insertion Inlet

P051 bit1) to see that the output value of the Toner
Insertion Inlet Cover Sensor is changed normally when
opening/closing the Toner Insertion Inlet Cover.
If it is normal, the value becomes 0 by driving the
Hopper Unit with the Toner Container Removing Tool
and opening the Toner Insertion Inlet Cover. When
closing the Toner Insertion Inlet Cover by hand, it
becomes 1.
3-1. When the Toner Insertion Inlet Cover is not
opened although the Hopper Unit is driven, check
the drive system from upstream (Hopper Unit ->
link mechanism of Hopper Tray -> Toner Insertion
Inlet Cover Unit).
If it is damaged, replace the damaged part and
then perform step 5 and later steps.
3-2. When the output value is not changed normally
although the Toner Insertion Inlet Cover can
be opened/closed, check the Sensor Harness
(to see if the harness is caught, disconnected
or physically removed, *including the Relay
Connector).
If there is no problem, replace the sensor. After
checking the output value in step 3, perform step
