Description
Error in Y Toner Insertion Inlet Cover Sensor (PS10)
Unable to detect opening of the Toner Insertion Inlet
Cover when removing the Toner Container.
Identify the cause of the error whether it is due to link
mechanism to open the Toner Insertion Inlet Cover or
problem at the Toner Insertion Inlet Cover Sensor side.
1. Perform the user mode (Adjustment/Maintenance>
Replace Specified Toner) to check if the Toner
Insertion Inlet Cover opens normally (damage, slide of
shaft area, etc.).
2. Check if the Toner Insertion Inlet Cover Sensor is
soiled and the installation of the sensor.
3. Check the service mode (COPIER> I/O> DC-CON>
P051 bit0) 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
5 and later steps.
4. If the problem is not solved by replacing the foregoing
parts, replace the Hopper Driver PCB (UN3) and then
perform step 5 and later steps.
5. Clear the error in service mode (COPIER>
FUNCTION> CLEAR> ERR), and then turn OFF and
then ON the main power.
6. 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.

Measures 1. Check the connection between the hopper/stirring
2. Check the connection between the toner feed screw
3. Replace the hopper/stirring supply motor.
4. Clean and replace the toner feed screw rotation
5. Replace the toner supply pipe unit.
6. Replace the hopper unit.
CAUTION:
Remedies 5 and 6 are taken when the motor is
overloaded due to toner adhesion in the unit or gear
interlocking failure, etc. Since it is difficult to identify the
cause, it is recommended to replace the unit.
