Description: Error in Y Toner Container Reciprocation HP Sensor (PS11). Unable to detect the change in the Release Holder Shift Cam HP Sensor status (ON -> OFF) when opening the cap so that open and close status of the cap cannot be judged.
Solutions: 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 bit15) 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 DC controller PCB 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.

Description: Error in Y Toner Container Reciprocation HP Sensor (PS11). 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.
Solutions: 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 bit15) 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 DC controller PCB and then perform step 4 and later steps. 4.

About Canon Servie Tool V5610

– Canon Service Tool V5610 is a tool used to perform maintenance on Canon printers and reset Canon printers after replacement of parts such as replacing ink absorbents, print heads, printer mainboard, and others. Based on the many cases we have encountered, the Service Tool is most often used to reset ink absorber counter value when the waste ink absorber is full.
– The ink absorber is going to be full of box, it has to be replaced or cleaned the waste ink absorber. Also, replaceing or cleaning the waste ink absorber, you need to repair or reset the waste ink counter value, cause those parts are concerned to each others.
– So using Canon Service Tool V5610 to reset the waste ink counter value becomes effective when the ink absorber is replaced or cleaned.

– Canon Service Tool V5610 can use to fix error code 5B00, 5B02, 5B04, 5B14, 1701, 1702, 1700 on your printer. You must enter Service Mode on your printer to use this Canon Service Tool.
– If the printer can not enter Service Mode, you can not reset it by Canon ST V5610. In this case, change EEPROM on the logic board.
