3.3.3 New Toner Detection
When a toner cartridge is changed, discrimination between new and secondhand toner
cartridges is performed by means of the new toner detection mechanism shown below.
<New Toner Detection Mechanism>
The rotation of the gear (1) of the toner cartridge is transmitted to the reset gear, and the rib of
the gear pushes down the reset upper lever attached to the drum unit.
By pushing down the reset upper lever, the linked reset lever turns and pushes up the new
toner actuator with its lever fitted on the main body. The detection mechanism detects that
new toner is provided.
- For high-capacity toner cartridges
The reset gear has two ribs. The new toner actuator is pushed up twice by these ribs,
allowing the presence of a high-capacity toner cartridge to be detected.
- For standard toner cartridges
The reset gear has one rib. The new toner actuator is pushed up once by this rib, allowing
the presence of a standard toner cartridge to be detected.
