15.7.1.2.2 Detailed Discussions of Bit 0
Select whether to enable or disable transfer bias pressure reduction mode.
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.
15.7.1.2.3 Detailed Discussions of Bit 1
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.
15.7.1.2.4 Detailed Discussions of Bit 2
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.
15.7.1.2.5 Detailed Discussions of Bit 3
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.
15.7.1.2.6 Detailed Discussions of Bit 4
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.
15.7.1.2.7 Detailed Discussions of Bit 5
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.
15.7.1.2.8 Detailed Discussions of Bit 6
Select whether to enable or disable noise reduction mode during terminal temperature rises. Select "Enable" to start slowdown at a temperature lower than normal
when printing on smaller-sized paper than B4. Slowdown control thus enabled prevents the thermal degradation of the fusing film grease, assuring smooth sliding
among the fixing film, heater and film guide to cut squeaks.
