2212 Set Dev DC
These SPs set the development dc bias for the standard speed mode and low
speed mode for each color, but take effect only when SP3501 001 is set to "1"
(Fixed). The dc development bias (absolute value) is set to –200 V, and the default
for each color is set to –500 V. These values are used only when automatic
process control is switched OFF (by setting SP3501 001 to "1").

2251 Force Tnr Supply
Use SPs to increase manually the supply of toner to the sub hopper of the
development unit to determine if toner supply is abnormal or to recover normal
operation of a color toner supply when image density becomes light. After you
press "Execute" the toner supply switches ON for 0.1 sec. and then OFF for 0.45
sec. four times for the select color or colors.

2252 Set Tnr Supply
Use these SPs to adjust the number of rotations done by the toner supply clutch
when SP2251 001~006 is executed manually. The number of toner supply cluth
rotations can be adjusted for each color. A high setting increases the number of
rotations and increases the amount of toner supply to the development unit,
resulting in a darker image for the selected color.
