Can't get Scanner to work

I have a Xerox scanner that disappears. So far the only way to fix it is to uninstall and reinstall the drivers.

You will need to install the software that came with the printer on the computer that it is connected to. The software will then run on the computer and "listen" for a command when you press the scan button. What is the make/model of your printer?

PLEASE SEE THE COMMENTS ON INSTRUCTIONS TO REINSTALL

If you have the orginal software that came with your scaner and it says that it is compatible to Windows XP, you may need to use the disc to reinstall it. YOu will first need to turn off the scanner and unplug it from the PC. Then uninstall the old software from install/uninstall in your control panel. (start>control panel>install/uninstall programs, search the list for your scanner software.)

If you do not have the software or it is not for Windows XP:

There is the link to a site with a driver download specifically for your scanner, instructions on installing it for windows XP and also a link to answers to problems for your specific scanner.

.
Before you begin any download make sure your virus control software is up to date.

First click on the link "Instructions for XP installation and print it out.
Next click on a driver for XP from the chart to download it. When a window pops up click save and browse until you locate desktop. Save this file to your desktop. It will be an .exe file.
Turn off your scanner and unplug it from your PC and uninstall the oldsoftware as advised above.
Click on your new driver file to install it. Follow instructions.
Once the driver is installed, plug the scanner back into the computer and turn it on.
Restart your computer.
It should now recognize your scanner.
Try a scan.

Having re-read your post it seems you have a visioneer scanner and installed HP scanjet drivers so this would definitely be an issue.

Ok, unplug usb lead between scanner and pc.
go into add/remove programs and remove any scanner software that may be showing.
load correct scanner driver (preferably the latest version from the manufacturers website).
plug in scanner usb lead when prompted and turn scanner power on.
It should then install correctly.

If usb stuff starts playing up it's usually easier to unplug it, uninstall it then re-install it using the latest drivers from the manufacturers' website. Don't just stick the disc in and re-install. Can save hours of messing about.

Did you plug in the scan unit and then installed the software?
If you did you will have to unplug or turn off your scanner then uninstall your software.
Reboot and the with the scanner turned off reinstall the software. If the install asks you to plug in your scanner, turn it on. If it asks you to reboot, then reboot. After rebooting, turn on the scanner then start the Easy Scan Utility. This should work.
It worked for me.

Were you able to download the driver from HP?

I would suggest unplugging the scanner, uninstalling the program, reboot, reinstalling the program and then plugging the scanner back in

i have vista home and mine worked fine until i installed a web cam and then it just gave up. But now it works great - here is what i did

unpluged both the scanner and the web cam
uninstalled everything to to w/ the scanner and the web cam.
Installed the driver from the CD and restarted my machine
Install the Photo 6 software
plug in the scanner - works like a champ.

have not reinstalled the web cam

Did you plug the scanner in before installing the software? Common mistake... Disconnect the scanner, uninstall the software completely, re-boot, open up the Device Manager, Click View-->Show Hidden devices--> Look for any scanner related drivers that are still installed for the scanner (they will moste likely be grayed out since it is unplugged) and uninstall them (Right click-->Uninstall). Re-boot again, install the software, wait for the software install to prompt you to plug in the device. Follow the quick start guide if it came with one. Check the manufacturers web site for updated drivers, software for you model.
