KEYBOARD WEDGE INSTALLATION (CONTINUED)
Manufacturer’s Recommendation
If the keyboard port of the host system cannot supply enough current, the use of an external power supply with the MS6220 Keyboard Wedge will be necessary. Powering the MS6220 directly from the computer keyboard connector could interfere with the operation of the scanner or the computer. Not all computers supply the same current through the keyboard port, so a scanner may work on one computer and not another (see caution statement on page 5).
