3.3.5 New toner detection
When a toner cartridge is replaced and a new toner cartridge is mounted, there is a need to
reset the develop bias voltage value (refer to
) to the initial value and to reset
prohibition of the print operation by clearing the display of "Toner Low" or "Replace Toner."
The old and new toner cartridges can be identified using the new toner detection mechanism
shown below.

New toner detection mechanism
When a new toner cartridge is mounted and the develop drive motor starts rotating, rotation is
conveyed to the reset gear via some other gears. Consequently, the rib on the reset gear
presses the reset upper lever, it turns ON the new toner sensor, and it is detected that a new
toner cartridge is mounted. If the develop drive motor further rotates, the rib on the reset gear
is disengaged from the reset upper lever, and the new toner sensor is turned OFF.
<For Standard toner cartridge>
Drive of the develop drive motor rotates the reset gear, and the rib on the reset gear presses
the reset upper lever. Consequently, the new toner sensor turns ON, and it is detected that a
new toner cartridge is mounted.
Fig. 2-11
<For Starter toner cartridge>
It is assumed that the starter toner cartridge is mounted when the main unit is turned ON for
the first time after the product is shipped out. The reset gear is not mounted.
