We're here to help with questions or problems with VueScan
Make sure you've tried using the
File | Default options
command first, since this solves more than 50% of reported problems.
If you're having a problem with VueScan hanging or not finding
your USB scanner, it's almost always a problem with the USB cable.
Try a newer and/or shorter USB cable, a different USB port, or a USB 2.0 hub.
If you have a Canon printer/scanner/copier and it's not responding, try
unplugging it, waiting a minute, plugging it back in and running VueScan again.
If VueScan can't find your scanner on the network, make sure the firewalls in
in your computer and your router aren't blocking mDNS (UDP port 5353).
If it's an older Canon printer/scanner/copier, also check UDP port 8612.
If you can't scan film with your flatbed, make sure you've removed the
white plastic cover from the lamp in the lid, and make sure you've put
the black plastic film holder on the glass properly.
You'll usually get a one or two line answer, but you'll get this answer
directly from Ed Hamrick :)
Many answers are form letters, but be assured that your problem report has been carefully read.
