3. Appendix: SP Mode Tables
Adjusts Vts (the Vt value for new developer). The TD sensor output is adjusted to this
2926 1
value during the TD sensor initial setting process.
2927* ID Sensor Control
Determines whether the ID sensor signal is referenced or not for the toner density control.
2927 1
Keep the default value in usual operations.
2928 Toner End Clear
Clears the following messages and counters without supplying the toner:
• Toner near end message
• Toner end message
2928 1
• Copies After Toner Near End Counter (SP2-224-001)
Do not use this SP in usual operations. When the toner in the development unit is
abnormally insufficient, the drum may attract the toner carrier to its surface. The toner
carrier damages the drum surface.
2929* Vref Adjustment
2929 1 Upper Limit
2929 2 Lower Limit
2930* TD Sensor Manual Setting
Inputs Vtref directly.
2930 1
"SP2-926-001" becomes invalid when this value is set.
2931* TD (V/wt%) Setting
Adjusts the timing of toner supplying. The more frequently toner is supplied under the
2931 1
smaller value. DO NOT use this SP in usual operations.
2932* Toner Density Control Level
[ 0=Normal / 1=Dark / 2=Light / 3=Darker / 4=Lighter ]
2932 1
This SP isn't valid unless "SP2-921-001" setting is 1=Normal2.
