Adjusts the development bias.
Development bias is automatically adjusted during
process control; therefore, adjusting these settings
has no effect while Process Control (SP3-125
Default: ON) is activated.
After deactivating Process Control with SP3-125,
the values in these SP modes are used for
printing.

/ 1%/step]
2208 009 Upper Limit *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.
