1109 Nip Band Check
Conducts the nip band check (
1109 1
Adjustment").
1110* Fan Control Timer
Specifies the fan control time. The fan motor keeps its operating speed for the specified
1110 1 time before changing the speed or stopping. The fan control timer prevents the exhaust fan
from suddenly stopping. This function protects the copier from overheating.
1159* Fusing Jam SC
Enables or disables consecutive jam detection at the fusing unit. If this SP is set to "1" (default:
1159 1 0), consecutive fusing jam alarm occurs (SC559) when the machine detects three
consecutive paper jams at the fusing unit.
1902 Display-AC Freq.
Displays the fusing lamp power control frequency (as detected by the zero cross signal
1902 1 generator). The displayed value is 1/5 the actual frequency: 10 and lower = 50 Hz, 11
and higher = 60 Hz.
1911* By-pass Envelope
The program dedicated to envelope printing runs when you enable this program
1911 1 (SP1-911-001) and you select "Thick Paper" as the paper type of the by-pass tray
( > System Settings > Tray Paper Settings > Paper Type: Bypass Tray).
SP2-XXX (Drum)
2001* CR Bias Adj
Printing

2001 1
automatically as charge-roller voltage control works. The value here is the base value for
the charge-roller voltage control.
