Web 802 the scanner no work,the message say the connection is closed

Check usb cable

Your firewall block the communication. You will need to get into your protection software and allow 'full' access of MP Navigator (EXT)

I have the same scanner and the drivers that came with the scanner don't work. Windows XP uses a generic twain driver that works, also most pictures viewer like XnView or Picasa uses the same. I'm using one called Wia-flatScanner_21 1.0(32-32).

Your Train source may be your scanner Twain driver. Reinstall the driver.

try plugging the USB connection at the back of you computer. If still didn't work out, delete the old driver install the new one, be sure cables are connected and intact. If still didn't work out bring your scanner to the service center near you

The readme says that some USB hubs have an issue.

I was having problems and was connected via a hub. I removed the hub and connected the printer directly to the back of the PC and voila scanning is all good.

ALex.

check the lenght of the cable
