Question about Canon LIDE20 Flatbed Scanner
Please help, my canon lide 20 flatbed scanner has recently started coming up with this error message: Unable to select TWAIN source
I have been using CanoScan4 for quite some time without any problems and this came unexpected (as most problems do).
I have since tried connecting it to various USB ports on my computer to no avail.
Any assistance will be appreciated!
Tried uninstallin and installin canon scanner drivers..nothing works..still seeing unable to select twian source..
so i tried an alternative..here we go..
on vista 64 os/vista any version..click Start>All programs>Windows fax and scan
next click new scan on top and that got me going.
some say there are issues with the way usb talks to old scanners with new operating systems like mine (vista 64). hope it helps until you find the actual cure.
