2922 1
Adjusts the toner supply time. The toner supply motor remains on for the specified time. To
validate this setting, select “0” in SP2-921-001. Specify a greater value if the user tends
to make many copies having high proportions of solid black image areas.
2926* Standard Vt [0.00 to 5.00 / 2.50 / 0.01 V/step] DFU
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. This SP is effective only when SP2-921001 is
“0”, “1”, or “2”.
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
• Toner near end counter
• Toner end counter
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 Limits Adjust the upper or lower Vref limit.
2929 1 Upper [0.50 to 3.50 / 3.20 / 0.01V/step] DFU
2929 2 Lower [0.50 to 3.50 / 0.70 / 0.01V/step] DFU
2994* ID Sensor Detection Temperature [30 to 90 / 30 / 1 °C/step]
2994 1
Adjusts the temperature threshold. The ID sensor signal is not referenced when the fusing
temperature is at the specified level or higher while the copier is recovering or starting up.
2996* Transfer Roller Cleaning [0 = No / 1 = Yes]
