Error in Cover Sensor (PS14) in M Toner Container
Description Unable to detect opening of the Toner Container Inner
Cover when removing the Toner Container.
Remedy Identify the cause of the error whether it is due to link
mechanism to open the Toner Container Inner Cover or
problem at the Toner Container Inner Cover Sensor side. ?
1. Perform the user mode (Adjustment/Maintenance>
Replace Specified Toner) to check if the Toner Container
Inner Cover opens normally (damage, slide of shaft area,
etc.). ?
2. Check if the Toner Container Inner Cover Sensor is
soiled and the installation of the sensor. ?
3. Check the service mode (COPIER> I/O> DCON> P024
bit9) to see that the output value of the Toner Container
Inner Cover Sensor is changed normally when opening/
closing the Toner Container Inner Cover. ?
If it is normal, the value becomes 0 by rotating the Set-on
Drive Shaft with the attached tool and opening the Toner
Container Inner Cover. When closing the Toner Container
Inner Cover by hand, it becomes 1. ?
3-1. When the Toner Container Inner Cover is not opened
although the Set-on Drive Shaft rotates, check the drive
system from upstream (Set-on Drive Unit -> Hopper Unit
-> Bottle Base Unit -> Toner Container Inner 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 Container Inner 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 Drum Driver PCB (UN4) 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.
1.) ' 2 - 5 ' = ' -3 ' = 3

3.) '?6'
= 6
4.) 8' + '?4' = 8 + 4 = 12
5.) 1 ? '?1' = 1 ? 1 = 0
