This flag is moved forth and back by the activation of the toner supply motor. When the flagtravels 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 tonersupply is completed by this step.Related Error CodeE025-0101: Y toner retainer motor errorE025-0201: M toner retainer motor errorE025-0301: C toner retainer motor errorE025-0401: Bk toner retainer motor errorThis error (overcurrent detection) occurs in the case that the power voltage of the toner retainer motor exceeds the specified value when supplying toner (while thestirring plate is operated).Related Error CodeE025-0102: Y hopper supply errorE025-0202: M hopper supply errorE025-0302: C hopper supply errorE025-0402: Bk hopper supply errorThis 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 screwis operated).M27 30M39 42CL1M3MN-CONDC-CONPS68 PS71[1][2][3][4][5][7][6][8][9] [10] [11] [12] [13] [14][15]
