Toner Overflow Sensor
2960*
Selects whether or not the toner overflow sensor is activated.
Transfer Cleaning Blade Forming
Applies a pattern of toner to the transfer belt at a defined interval between
sheets on the transfer belt in order to reduce friction between the belt
surface and the cleaning blade.
2964*
Under conditions of high temperature and high humidity, the density control
feature may reduce the amount of toner, which also reduces the amount of
toner on the surface of the transfer belt. With less toner on the belt, the
friction between the belt and the blade increases, and could cause the blade
to bend or scour the surface of the belt.

Grayscale Limit
Controls the halftone density level to prevent deterioration of the OPC. The
2972*
halftone density is detected by the ID sensor, and the machine adjusts the
intensity of the LD beam according to the upper/lower limit setting.
Upper Limit
Defines the upper limit for grayscale.
001
A larger value allows a wider range of halftones at the pale end of the scale.
If the image contains pale areas with fuzzy borders surrounded by dark
areas, reduce this value to make the borders clearer.
Lower Limit
002
Defines the lower limit for grayscale.
