[Ras dagbandoo]

i went to clean a customer's C5030 coppier using a blower. after which there was an error code E0025- 001A0. having used the attached tool at the back, the error keeps alternating from E0025-01A0 to -02A0, -)3A0 and vice versa. whats the remedy.
please help

E025-01A0
Description:
Error in Y Toner Container Cam HP Sensor (PS5)
Unable to detect the change in the Toner Container Cam HP Sensor status (ON -> OFF) when opening the Toner Cap so that open and close status of the Toner Cap cannot be judged.

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 bit4) 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.

Description:
Error in M Toner Container Cam HP Sensor (PS6)
Unable to detect the change in the Toner Container Cam HP Sensor status (ON -> OFF) when opening the Toner Cap so that open and close status of the Toner Cap cannot be judged.

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 bit5) 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.

Description:
Error in C Toner Container Cam HP Sensor (PS7)
Unable to detect the change in the Toner Container Cam HP Sensor status (ON -> OFF) when opening the Toner Cap so that open and close status of the Toner Cap cannot be judged.

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.

i have used the attached tool and also the gears seemed ok after checking. the problem now is the gears wont turn using the attached tool. the machine now gives error code E025- 210. how do I locate the sensors for may be cleaning possible dust? any video?
thanks for replys
