Is the voltage between pins 1
(+24VDC) and 2 (GND) of
connector P2 on the driver PCB
24 Volts DC?
No
Check if +24VDC is supplied
between pins 4.5 (+24VDC)
and 2.3 (+24VRET) of
connector P13 on the driver
PCB. If not, check the power
supply output on the low-
voltage power supply PCB.
Yes
Replace the scanner unit.
