Toner Near-Empty and Toner Empty detection control

• The Sub Hopper Empty Switch provided in the Sub Hopper detects a toner empty condi-
tion.
• A toner near empty condition is detected when the Toner Bottle is rotated 30 complete
turns continuously. The number of times that the Main Hopper Solenoid is energized is
counted to provide the basis for the toner near empty condition.
A. Replenishing operation
1. As the level of toner in the Sub Hopper becomes low, the magnet portion lowers
and the Sub Hopper Empty Switch (S4) is eventually actuated.
2. When a toner empty condition is detected, the Main Hopper Solenoid (SL2) is ener-
gized to let the Toner Bottle start rotating. When the Main Hopper Solenoid (SL2) is
deenergized, it brings the Toner Bottle to a stop.
