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.

[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
