Step 1: V Adjustment
SG
This machine uses two ID sensors (direct reflection type). They are located at the
front and rear of the transfer unit. Only the front ID sensor is used for process
control. The ID sensor checks the bare transfer belt's reflectivity and the machine
calibrates the ID sensor until its output (known as V
• V = 4.0 ± 0.5 Volts
SG
This calibration compensates for the transfer belt's condition and the ID sensor
condition, such as dirt on the surface of the belt or ID sensor.
