I have recently re-instaled the drivers for a CanoScan n676u on Windows XP and teh PC recognises the scanner and can successfully test that it is there but when I press the copy button on hte scanner...

Have you also installed the software. You may have to use the scanner through windows, and not with the buttons on the scanner.
You may have just installed the twain drivers and not the software to be able to use buttons and advanced settings

My epson 3490 photo scanner isn't working theres a red light on the front of the scanner which is flashing

If the start button light is flashing red, it is because of one of the following problems:

  • The scanner is not connected to your computer properly or your software is not fully installed.
  • The transportation lock is locked. Slide the lock to the unlock position.
After trying these solutions, unplug the scanner to turn it off, then plug it back in.

Make sure the scanner is unlocked. Lock switch is either on the bottom, or under the scanner lid near the hinges.

Installation problems

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.

Scanner not working

Hi, there are a couple of things you may want to try. Some of these if not done right might make you loose access to your scanner, proceed at your own risk. 1) really lock your scanner before booting to windows, then proceed to scan, then it will tell you that is locked, follow directions, remove, unlock, plug back, proceed to scan; or 2)use a different USB port (front and back/side); or 3) download and use (preferably new) drivers @ or use the CD installer that came with the product. Uninstall your scanner: right click My Computer, Properties, Hardware, Device Manager, look for your scanner, right click, uninstall. or Start, control panel, add/remove programs, remove your scanner programs. You have to reinstall them all again (better with new drivers). Hope this work for you and good luck.
