Question about Canon CanoScan LiDE 70 Flatbed Scanner

1 Answer

My scanner sounds broken and reads "2, 250 TWAIN Error"

My scanner has recently started grinding, as if part of it is stuck in place, and doesn't come up on my computer or seem to move at all.

I've tried plugging and unplugging the scanner but it sounds like it is physically jammed. Canon's website said to unlock the scanner but mine is always unlocked. Is it really just jammed and if so, would getting inside it and moving it myself fix anything?

Are you sure it hasn't become locked underneath? try repeating the unlock procedure a few times?

Trouble shooting


The "car sound" could be an indication that the scanner is locked. Check the lock switch on the bottom of the scanner. Move the switch back and forth a few times and then leave it in the locked position. Another possibility is that you are scanning heavy items such as books. If too much weight is placed on the scanner glass, then pressure could be enough to prevent the scanning element from moving as it should.

The code 201 sometimes can indicate a power issue...meaning the scanner is not getting enough power. Try connecting the usb cable to a different port on the computer (preferrably directly to the computer and not through a USB hub).

TWAIN message


Hello,

The Twain error message sounds like a Windows error... I wonder if the software you are trying to use is for Windows, and not MAC.

Scanner will not connect to computer


'Twain' only means 'Technology without an important name', as this is refering to your printer/scanner, i would suggest that you disconnect the printer and remove any driver from Add/Remove programmes. Re-install printer software/driver and re connect printer when prompted and if possible in a different usb port, if that's how it's connected. If the problem persists and the pc is unable to communicate with the printer the fault will lie with the hardware. Hope it's only a driver glitch.

Error Message-- Error in shading position (-4431)


The issue at hand here is a sensor error. Cut the power to the machine for at least five seconds. Then reboot the scanner and the sensors should reboot. This solved the problem for us. Good luck to you.
