Toner Over Sens
2960
[0 = No, 1 = Yes]
Selects whether or not the toner overflow sensor is activated.
Transfer Cleaning Blade Forming
[0 ~ 30/ 3 / 1 sheets]
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.
2969 LD PWM Select
LD PWM Select
[1 ~ 5 / 1 / 1 step]
Changes the LD power PWM control for printed copies. A smaller value produces

a lighter image. Use this SP to adjust the image density for printing from a
personal computer:
1:100% 2:87.5% 3:75% 4:62.5% 5:50%
