● Toner Supply Control/Toner Level Detection
Toner is supplied from the Toner Container to the Developing Assembly. At the same time,
toner level in the Hopper Unit is detected. The light emitted from the Toner Level LED PCB
is received on the Toner Level PT PCB, and toner level in the Hopper Assembly is detected
according to the light reception.

Title Description Supply timing
Supply to Toner is supplied from When the output result of
the Hopper the Toner Container to Toner Level PT PCB (UN22
the Hopper Unit. to UN25) is changed from L
to H.
Supply to the Toner is supplied from When toner supply is
Developing the Hopper Unit to the determined necessary by
Assembly Developing Assembly. the result of ATR control.

Operation of the host machine
The Toner Container Motors (M7,
M9, M11, M13) are driven and
toner is supplied until the Sensor
shows L.
The Toner Supply Motors (M6,
M8, M10, M12) are driven for 1
block.

description
Empty toner warning Prediction from the Developing
1 (approx. 10% left Assembly toner supply count (Judged
until the toner is out) from the number of toner supply to the
Hopper Unit.)
Empty toner (approx. The output result of the Toner Level
0% left until the toner PT PCBs (UN22 to UN25) is changed
is out) from L to H and the H state continues
for 60 seconds.
*1: Developing Assembly supply count shows the level of toner supplied from the Hopper Unit
to the Developing Assembly.
NOTE:
The Developing Assembly supply count is reset in the case that the Toner Container is
removed and then installed while absence of toner is detected, print operation is made,
and then presence of toner is detected. Therefore, there is no need to reset the service
mode. Note that the supply count is not reset in other cases.
Because the Hopper Assembly in this equipment is very small, printing cannot be
executed after absence of toner in the Toner Container is detected. Therefore, the
3-level display, which is available with the existing models, is not available.
In the case that the Toner Container is replaced while continuous printing is available,
warning message will not be cleared. To clear the warning message, select the
following: User Mode > Adjustment/Maintenance > Replace Toner While Printing Is Still
Possible, and then select the target color.
Example: when selecting black
A message "Did you replace the black toner while printing was possible? (Perform this
operation only if toner was replaced when printing was possible.)" is displayed. By
selecting "Yes", the supply count is reset and the warning is cleared.
