[TD Vcnt] TD Sensor Vcnt Control
Humidity *BCU [0 or 1 / 1 / -] Alphanumeric
0: Disable, 1: Enable
2223 002
Enables or disables the Humidity Auto Correction. This corrects the Vcnt value for
the current humidity. This correction is applied to both the Vcnt values automatically
adjusted during developer initialization and manually adjusted with SP2-224-1 to 4.
If this correction does not work well under certain environmental conditions or due to
a defective humidity sensor, deactivate the Humidity Auto Correction and adjust the
Vcnt value in SP2-224-1 to 4 (by trial and error).
Toner Fill Up *BCU [0 or 1 / 0 / -] Alphanumeric, DFU
0: Deactivate, 1: Activate
2223 003
Activates or deactivates the Toner Fill Up mode, which fills up the toner supply tube
with toner during developer initialization. This function is required only at machine
installation. Although the default is “0”, the factory setting is “1”. After toner fill-up
occurs during machine installation, the setting is changed to “0” automatically.
