CL1: Developing clutch
PS68 to PS71: Toner Supply Level Sensor
This machine has toner supply level sensors (PS68 to PS71) to perform accurate toner supply.
This sensor detects the sensor flag installed at the supply screw shaft. This flag is moved forth and back by the activation of the toner supply motor. When the flag
travels once, the supply screw rotates to supply the specified amount of toner into the developing assembly.
At toner supply, the side driver PCB monitors this sensor while activating the hopper motor. After toner supply is completed, the motor is stopped. Accurate toner
supply is completed by this step.
Related Error Code
E025-0101: Y toner retainer motor error
E025-0201: M toner retainer motor error
E025-0301: C toner retainer motor error
E025-0401: Bk toner retainer motor error
This error (overcurrent detection) occurs in the case that the power voltage of the toner retainer motor exceeds the specified value when supplying toner (while the
stirring plate is operated).

E025-0102: Y hopper supply error
E025-0202: M hopper supply error
E025-0302: C hopper supply error
E025-0402: Bk hopper supply error
This error occurs in the case that the detection time for toner supply level sensor exceeds the specified value when supplying toner (while the toner feeding screw
is operated).
