Select "Enable" to avoid image defects (black spots) produced by transfer bias leaks occurring in a low-pressure region, such as one at a high altitude. This setting

regulates the transfer bias to keep it from exceeding a predetermined level during printing.

Select whether to enable or disable developing assembly idling mode. Select "Enable" to drive the main motor for a specified period of time to apply idling and

developing bias (AC + DC) to prevent the thinning of the image density when the unit is installed or the developing unit is replaced in a low-temperature, low-

humidity region. This mode works only on a new developing assembly and before a toner cartridge is loaded.

Select whether to enable or disable black belt addition mode. If the user uses paper that causes fixed toner on paper to be fused and adhered to drum, selecting

"Yes" will clean the drum by forming a black band on the drum surface during the reverse rotation which is performed after printing on 50 sheets.

Implementation of this mode could result in a drum life falling short of its life expectancy.

Select whether to enable or disable post-rotation reduction mode. Selecting "Enable" will reduce the noise caused by the polygon motor by stopping the motor

immediately after post-rotation.
