Toner end sensor
The agitator mixes toner and sends it to the toner supply roller and development roller as shown above
[1]. The toner detection feeler comes down when the toner tank is out of toner as shown [2], and then
the toner end sensor [B] detects toner end.
The toner end sensor detects toner end by the voltage output. When the output from the toner end
sensor is below a given level, the machine displays “Replace Required Soon: Print Cartridge”.
After the additional pages have printed, printing stops and then the “Replacement Required: Print
Cartridge” message remains on the display.
Main Motor Rotation Count
The time to replace the AIO cartridge can also be determined by the length of time the main motor has
been rotating.
When toner end is detected, “Replacement Required: Print Cartridge” is displayed alternately with
‘Ready’.
Toner Overflow Prevention
With the main motor rotation count feature, the machine can be set to stop printing after the print total
exceeds a certain set value. If the print count exceeds this value, then “Replacement Required: Print
Cartridge” remains in the display. Then a new AIO cartridge must be installed.
This feature is a safety measure to prevent the used toner tank from becoming full (there is no toner
overflow detection mechanism).
