Initialization
*BCU Enables or disables the Vcnt Auto Adjustment
when detecting a new development unit.
When the machine detects a new development
unit, developer initialization automatically starts.
During the developer initialization, Vcnt is
automatically adjusted so that Vt is within 3.0
±
0.1V.

Humidity
*BCU 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 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.
