hi
here is the link

Located new Vista driver installed and worked, both driver and operator error.

Its possible you've set your faxes to send in FINE resolution (200 dpi), I am not sure about MS Fax, but in WinFax you can select both Standard Resolution and Fine resolution as the default for sending faxes.

You need 9V/1A supply (with +9V at center pin) for your model with beige case. Do not use 22V/1.5A supply for old 33.6k model with
gray case. The shapes of the cases are very similar (56k has fever
leds, no external volume control, and no connectors for external
telephone equipment and external speaker), but the power supply
voltages and currents are completely different.
I hope this will help.
