hello you already tried to open FIXING / FEED ASSEMBLY, turn on the printer and enter the service mode: COPIER-FUNCTION-CLEAR-ERR_OK you turn off and turn on the machine when the screen tells you to close the door, close the FIXING / FEED ASSEMBLY and main door

the other would be to take out the BOTTLE EXCHANGE COVER ASSEMBLY, activate the sensors with pieces of paper and put the toner bottle, check if the cyan toner bottle is rotating

Remedy:
Identify the cause of the error whether it is due to
mechanical problem to open/close the Toner Cap or
problem at the Toner Container Cam HP Sensor side. ■
1. Check if the Toner Container Cam HP Sensor is soiled
and the installation of the sensor. ■
2. Rotate the Set-on Drive Shaft a little with the attached
tool, and check the service mode (COPIER> I/O> DCON>
P024 bit6) to see that the output value of the sensor is
changed. ■
Since it is difficult to check the screen while rotating it,
repeat the operation to rotate 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 Toner Cap. Even if it is normal,
be sure to perform step 4 and later steps. ■
2-1. If there is an error in rotation of the Set-on Drive
Shaft, 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 Set-on Drive Unit is not driven although
the Set-on Drive Shaft rotates, check if it is driven by
removing the Hopper Unit. ■
If it is not driven, replace the Hopper Unit and then
perform step 4 and later steps. ■
2-3. When the output value of the sensor is not changed
although the Set-on Drive 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 Drum Driver PCB (UN4) 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
