8.3 TONER OVERFLOW DETECTION
The toner overflow detection mechanism stops copier operation when the
used toner tank gets full. When the tank gets full, the pressure of the used
toner pushes up a movable plate [A] mounted in the top of the used toner
tank. As this plate moves up, it raises the toner overflow actuator [B]. When
the actuator moves into the toner overflow sensor [C], the CPU starts to blink
"E70" on the operation panel. After the "E70" starts to blink, 250 copies can
be made. Then, after 250 copies the "E70" stops blinking (stays on) and
copying is inhibited.
