Basic info. Windows XP Pro machine, 768 RAM, 933, all OS updates current...

We just got a Microtek ScanMaker 5700 in as an eval. device [It's attached directly to a USB port on the machine, not a hub]. For the most part, we like it quite a bit more than the most of the scanners we're using, but we have a strange issue with it.

Whenever we use it, we have to cycle the power on it...and after the scanner goes to "standby" mode, still powered up, it disappears from Windows...in other words, when you try to scan something new, you get a "scanner not found" message until you reboot the scanner. Then, by the time you scan the third or fourth job, the PC just hangs. [I'm assuming that's a memory tweak yet to be perfected, so that doesn't concern me as much.]

Latest drivers installed for the 5700 [version 5.75].

I seem to remember that this might be a WIA conflict...[Windows Image Acquisition]...any ideas?

Thanks all.
