Function / [ Setting ]
* Forces toner to be supplied to the development
BCU unit for the number of times specified by this SP
mode.
1 time: The toner supply clutch turns on for 0.7 s
and off for 1.3 s.
[ 0 to 3 / 2 / 1/step ]
* Selects the toner supply method.
BCU [ 0 to 2 / 1 / 1/step ] Alphanumeric
0: Fixed supply (with the supply rates stored with
SP2-208-5 to 8)
1: Fuzzy control supply
2: Proportional control supply (using the Vref
values stored with SP2-224-5 to 8)
Sets the toner supply rate used when the toner
supply method (SP2-208-1 to 4) is set to '0' (fixed
supply mode).
[ 0 to 100 / 5 / 1%/step ]
* Specifies the maximum possible toner supply,
BCU expressed as a percentage of the maximum
# amount of toner that can possibly be supplied for
a sheet of paper.
If too much toner is supplied to the development
unit especially for black or in the low humidity
condition, this may cause dirty background due to
insufficient agitation. This SP mode limits the
maximum possible toner supply for black and only
in the low humidity condition for color.
[ 20 to 70 / 42 / 1 %/step ] DFU
NOTE: The main switch must be turned off and on
to effect the setting change.
* Adjusts the toner supply amount (fixed rate) when
BCU making multiple prints of pages with low image
ratio (coverage).
When printing with a low image ratio, toner
concentration is controlled only with Vt outputs
since pixel count is not done for low image ratios.
This may cause the attraction force between toner
and carrier to increase, resulting in low image
density on outputs. To prevent this, the machine
counts the number of pixels and supplies a fixed
amount of toner if the accumulated number of
pixels becomes greater than the specified level.

* Displays the total time that the toner supply clutch
BCU has been on.
This data is stored in the memory chip on each
toner cartridge.
