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 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.

Select whether to enable or disable flicker reduction mode. Select "Enable" and enter a count to modify fusing temperature control to cancel fluorescent flicking

during printing.

Implementation of this mode would degrade the throughput.

Select whether to enable or disable silent mode. Select "Enable" to modify the registration loop amount and thus reduce noises or squeaks the registration rollers

produce after picking paper from the individual paper inlets.

Select whether the pre-rotation is to be extended.

If white streaks appear in the image in the H/H environment, selecting "Set" extends the pre-rotation by five turns. During the extended period, the charge Vpp is

increased to prevent white streaks from occurring.

if B4 recording paper and A4 recording paper are set and an A4 extra-long image

(*) is received, printing will be on the B4 recording paper.

if B5 horizontal recording paper and A4 recording paper are set and a B4 image is

received, printing will be by division and on B5 horizontal recording paper.
