If so that would seem to indite the plug or its contacts The first thing I suspect in a case like this is a corrupted driver. Have you tried going to the Control Panel/System/Device manager to check for problems? If the computer sees a problem it will flag the offending piece of hardware with a yellow symbol at the left hand end of the line describing the hardware. You should start by checking the Printers group in the Device Manager, then the Imaging Device group. If either shows an indication of a problem; select that item, click on Remove, then ok (and I think there is another OK), then close the control panel and shut down. When you re-start the machine should find the hardware whose drivers you just removed and it will install new drivers from its stockpile in the CAB's folder. If it isn't a driver problem, then I would check out the cables: kinked, dirty plug contacts (see my opening remark above), plugs not seated properly, plugs corroded (in this last case simply removing and reinstalling the plug will often clean the contacts sufficiently). I wouldn't rush out to buy a new scanner just because this one is acting up a bit, after all you did say that it worked OK before. Hope this helps, Wally --=====================_6743475==_.ALT Content-Type: text/html; charset="us-ascii" Hi Ted, Wally Neilson here;
