I have changed fax modems 2 times and now went back tomy original plug and play USRobotics 5637. Unfortunately it will only send a fax on the reboot?? I have uninstaleed everything and reinstalled it all several times now. If I try and send a fax it says invalid printer name?? When I reboot the computer any that were "pending" are sent. I cannot figure this out. Can someone help?? The USRobotics team syas it is a problem with windows fax and scan/ I do not know why as it owrked perfectly right out of the box but then I had to upgrade it as this one did not do what the "salesman" said it would!! I upgraded and it was a nightmare so I tossed it out nad went back to this one , but unfortunately I amunable to get it to work correctly.
(Win 7 64 bit)
Thanks in advance
