M2004 Emits Three Error Beeps when Attached to a Thin Client
Article ID: 01348726
M2004 emits a triple beep when attempting to scan in Countertop Scan Pattern Mode (hands free omnidirectional). The M2004 is connected to a thin client and can scan in any other mode. When attached to a typical IBM PC, the scanner will work in hands free omnidirectional mode.
The thin client is not supplying enough power through the PS/2 keyboard wedge adapter cable.
Attach a power supply to the scanner while it is connected to the thin client. Use the power supply part number 50-14000-008 (US, 117 VAC)
