Sp2-Xxx (Drum) - Ricoh K-C3 Service Manual

B245/B276/B277/B268/B269 Service Manual
Inputs the fan control time. The fan maintains normal speed for the specified
time after occurrence of an SC or following entry into Warm-up mode, Low
Power mode, or Night/Off mode.
Fusing Jam SC Code Setting
1159*
This SP mode detects SC559. Set this SP mode to 'Yes' if the machine
1159 1
experiences paper jam problems on a continual basis.
Display-AC Freq.
1902
Displays the fusing lamp power control frequency (as detected by the zero
1902 1 cross signal generator). The displayed value is 1/5 the actual frequency: 10 =
50 Hz, 12 = 60 Hz.
Feed Clutch Boost
Adjusts the amount of extra push that the feed clutch gives to the paper after
the skew has been corrected at registration. This feature helps the registration
1903*
roller feed certain types of paper (such as thick paper). Increase the value if
thick paper is jamming after feeding from the registration roller.
1903 1 By-pass tray
1903 2 2nd, 3rd, 4th tray
Optional Tray Adj.
1908*
Adjusts the reverse time for the upper and lower paper lift motors.
1908 1 1st optional
1908 2 2nd optional
By-pass Envelope
1911*
[0 = Disabled / 1= Enabled
The program dedicated to envelope printing runs when you enable this
1911 1 program (SP 1911 1) and you select "Thick Paper" as the paper type of the
by-pass tray (System Settings > Tray Paper Settings > Paper Type: Bypass
Tray).

Charge Roller Bias Adjustment
2001*
Printing
Adjusts the voltage applied to the charge roller when printing. The actually
2001 1
applied voltage changes automatically as charge roller voltage correction is
carried out. The value you set here becomes the base value on which this
correction is carried out.
ID sensor pattern
2001 2 Adjusts the voltage applied to the charge roller when generating the Vsdp ID
sensor pattern (as part of charge roller voltage correction). The actual charge-
roller voltage is obtained by adding this value to the value of SP 2001 1.
Erase Margin Adjustment
