*BCU Specifies the maximum possible toner supply,
# 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.
[0 to 100 / 63 / 1 %/step] DFU
NOTE: The main switch must be turned off and on
to effect the setting change.
*BCU Adjusts the toner supply amount (fixed rate) when
making multiple prints of pages with low image
*BCU
ratio (coverage).
*BCU
When printing with a low image ratio, toner
*BCU
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.

*BCU Specifies each constant to adjust the toner supply
