7.8.6 Toner Supply
0020-4595
imagePRESS C1+ (Printer) / imagePRESS C1+
Toner of each color is sent from the toner bottle to the hopper unit, and sent to the developing assembly on a timely basis.
There are two supply routes; "hopper supply" between the toner bottle and hopper unit, and "developing assembly toner supply" between the hopper unit and de-
veloping assembly.
In the "hopper supply" as the first step of toner supply, when the toner bottle is set to the main unit, toner in the bottle freely falls into the hopper unit.
In addition, since the machine drops the toner remained in the bottle into the hopper unit, it rotates the toner bottle motor (M27 - M31) after the "developing assembly
toner supply". This rotates the stirring plate and removes the toner in the bottle.
The "developing assembly toner supply" as the next step is performed by the hopper motor (M39 to M43), developing motor (M3), and developing clutch (CL1).
The hopper motor (M39 to M43) rotates the toner in the hopper unit, and it drives the toner supply screw and transports the toner to the toner feeder screw. During
this operation, the machine turns on the developing clutch (CL1) and rotates the developing motor (M3). This rotates the toner feeder screw and transports the toner
into the developing assembly.
A series of this electric load operation is controlled by the side driver PCB and DC controller. The side driver PCB calculates the toner consumption volume based
on the ATR control results. Accordingly, the side driver PCB judges the toner supply volume and supplies required volume of toner to the developing assembly.
