Forced Toner Supply

Push [Execute] to force toner supply. Make a copy and check the image
density. This SP supplies more toner to make light copies darker. Each time
this SP is done, toner is supplied one time.
After [Execute] is pressed the main motor, charge unit, and other
components turn on, then the machine supplies a prescribed amount of
toner to the development unit.
If image density is light, use this SP to recover from a low toner supply
problem.
After executing forced toner supply, the Vsp value displays in the range
0.1 to 0.4 V, and thereafter, the value is stabilized (near 0.4 V) for
subsequent printouts.

Toner Supply Setting

1 Gain
This SP setting determines the supply GAIN for toner supply based on the
readings of the ID sensor (Vsp/Vsg). This value is the threshold setting used
calculate toner supply with the toner supply coefficient set with SP2208-2.
The Vsp/Vsg value is used to fetch the corresponding value from the GAIN
lookup table.
Increasing the value of this setting raises GAIN for image density control.
[0 to 9/1/1]
0: Lowest, 5: Medium, 9: Very High

2 Supply Capacity

This SP sets the coefficient for toner supply control.
This coefficient is used in a calculation with GAIN value, and width of the
paper to determine the amount of toner supply.
Increasing the value of this setting raises the amount of toner applied to
control image density.
