scanner twain problem

[Ish]

i'm having a major problem with this and have tried everything i can to sort it.

when i try and scan something i get the following error "COULD NOT OPEN THE TWAIN SOURCE. MAKE SURE THERE IS A VALID SOURCE FOR YOUR SCANNER IN THE TWAIN DIRECTORY FOUND IN THE WINDOWS DIRECTORY"

this happends even if i try my usb canon scanner or an old parallel port one. the scanner shows as working fine in properties.

i have done all of the following and nothing has sorted it:-

.updated scanner drivers and removed old ones.tried all the updated drivers from canon website.

.installed windows 2000 instead of win xp sp2 i was using

.reset bios to default settings

.tried different usb ports

.tried another usb cable

.tried different scanning software

i can't understand why both scanners will not work on win xp sp2 or win 2000

this is the most annoying pc problem i have EVER had

try using the WINDOWS NT drivers that come with the drivers you have for them ...or look for an alternative driver maby the next model up for it


please post the exact make model number for both so we can look see if we can find supporting drivers for you

 

[Ish]

the model i am using is a canon canoscan N650U

i have tried the driver that came on the cd as well as the latest drivers from the canon uk & europer websites.

One suggestion from the site

And another

It sounds like you have installed CLEAN, two different scanners - seems to rule out many of the obvious questions.

It's not something daft like being set to the wrong source is it - some cameras are also Twain devices, but if you resorted to a clean OS install, that tends to rule out other devices interfering.

Any other USB devices? do they work ok? - though even if the USB is malfunctioning, that doesn't explain why the partallel one wouldn't work either.
