Toner supply control/toner level detection
Supplies the toner in the Toner Container to the Developing Assembly. At the same time, it
detects the toner level inside the Hopper Unit.

Timing to supply
Operation of main unit
Supply to
hopper
To supply developer in
the toner container to
the hopper unit
When the output result of
piezo sensors (TS1 to 4) is
changed from H to L
The toner container drive motors
(M9 to 12) are driven for 2
seconds (*

)
Supply to
developing
assembly
To supply developer in
the hopper unit to the
developing assembly
Toner supply is determined
to be necessary by the result
of ATR control
The developing motors (M5 to8)
and the toner supply clutches
(CL2 to 5) are driven for the
specified period.
*1: If the output result of piezo sensors TS1 to 4 keeps L despite drive of M9 to 12, make M9
to 12 driven for 2 seconds and then stopped for 2 seconds and repeat this procedure up
to 20 times. Due to this operation, when performing continuous printing with high image
ratio, "Preparing toner..." may be displayed on the UI screen. In that case, wait for up to 80
seconds until the machine is recovered.
