Sub Hopper Toner Empty Detecting Mechanism - Muratec MFX-2500 Field Engineering Manual

2.4.9.5 Sub Hopper Toner Empty Detecting Mechanism

A toner-empty condition in the Sub Hopper is detected by the Magnet Lever that moves up and down as
the Sub Hopper Toner Agitating Lever turns and actuates and de-actuates the Sub Hopper Toner Empty
Switch.
While the amount of toner in the Sub Hopper is more than the predetermined amount, the Magnet Lever
rests on the toner, keeping the Sub Hopper Toner Empty Switch de-actuated even when the Sub Hopper
Toner Agitating Lever turns. As toner is consumed, the Magnet Lever lowers to eventually actuate the
Sub Hopper Toner Empty Switch, at which timing the machine detects a toner-empty condition in the
Sub Hopper.
