Step 1: Vsg Adjustment - Ricoh B230 Training Program

ID sensor: Calibrated so that the signal, when
reading the bare transfer belt is 4.0 ± 0.5 Volts
•
This compensates for changes in the image transfer belt and
ID sensor
•
This is always done during initial process control. This is only
done if the VSG adjustment counter (SP3-510-007) is more
than the value set with SP3-511-007 (default: 500) during a
job or at job end.
SC400 is displayed if VSG is out of adjustment
range sequentially 3 times.
SP3-321: Forced VSG Adjustment for each sensor

Step 1: VSG Adjustment

This machine uses four ID sensors (direct reflection type) for the process control.
Each sensor detects a pattern for each color (see the 'Printing Process' section).
The ID sensor checks the bare transfer belt's reflectivity. Then the machine
calibrates the ID sensor until its output when reading the bare transfer belt (known
as VSG) is as follows.
VSG = 4.0 ± 0.5 Volts
This calibration compensates for the transfer belt's condition and the ID sensor
condition. For example, dirt on the surface of the belt or ID sensor.
VSG adjustment is always done during initial process control. But, at other times, it
is only done if the VSG adjustment counter (SP3-510-007) is more than the value
set with SP3-511-007 (default: 500) during a job or at job end.
SC400 is displayed if VSG is out of adjustment range sequentially 3 times.

SP 3-325: Shows the results of the VSG adjustment (automatic or forced VSG
adjustment) - 7 digits (Front, Bk, C, Center, M, Y, Rear: All 7 sensors are calibrated
even though only four are used for process control
