2926 1
Adjusts Vts (the Vt value for new developer). The TD sensor output is adjusted to this
value during the TD sensor initial setting process.
2927* ID Sensor Control [0 = No / 1 = Yes]
2927 1
Determines whether the ID sensor signal is referenced or not for the toner density control.
Keep the default value in usual operations.
2928 Toner End Clear
2928 1
Clears the following messages and counters without supplying the toner:
•
Toner near end message
• Toner end message
• 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 Adjust the upper or lower Vref limit.
2929 1 Upper Limit [0.50 to 3.50 / 2.40 / 0.05 V/step] DFU
2929 2 Lower Limit [0.50 to 3.50 / 0.50 / 0.05 V/step] DFU
2930* TD Sensor Manual Setting [0.00 to 5.00 / 0.00 / 0.05 V/step]
2930 1
Inputs Vtref directly.
“SP2-926-001” becomes invalid when this value is set.
2931* TD (V/wt%) Setting [0.01 to 1.50 / 0.40 / 0.01 /step]
2931 1
Adjusts the timing of toner supplying. The more frequently toner is supplied under the
smaller value. DO NOT use this SP in usual operations.
2932* Toner Density Control Level [0 to 4 / 0 / 1 /step]
2932 1
[ 0=Normal / 1=Dark / 2=Light / 3=Darker / 4=Lighter ]
This SP isn’t valid unless “SP2-921-001” setting is 1=Normal2.
