Check to see if you have the directory c:\windows\twain_32 with subfolder for your scanner.

Also check that you have the twain drivers in c:\windows\system32

The scanner is not available while in use by another application or user i get this darn error. I use this scan multiple times a day and all of a sudden i see this.... why?


Hi,

The error message could be Twain Driver error or ScandAll pro Application error. Please go through the followings:

SCANDALL-PRO APPLICATION ERROR:

Error Code: [SA01020E] No scanner is found.
There is a possibility that no scanner is connected, the connected scanner is not turned on, or the scanner is currently used by some other application.

Status: [Scan] or [Select Scanner] is specified, but no connected scanner is found. Or, the scanner is currently used by some other application.

Action: Make sure that the scanner is connected and is turned on. If the scanner is currently used by some other application, use the scanner after the application ends. Make sure that the driver selected on the [Scan] tab of [Preferences] in the [Tool] menu is installed correctly.

TWAIN DRIVER ERROR:

-The scanner may be OFF or not connected. Check the power supply of the scanner or connection with PC.
-The scanner may be already in use by other application or the "Scanner and Camera" in [Control Panel].Close other application or "Scanner and Camera" in [Control Panel]

-The connected image scanner is not a model supported by this driver. No image scanner is connected. The cable is disconnected.Check whether the image scanner is connected.

-Another application may already be using the image scanner. Alternatively, the TWAIN driver may have been activated twice.Terminate all applications, and start scanning again.

For more information, please refer to the help contents of Scanner utility/Twain driver and scanning application installed on your PC.Hope the above information is helpful.

Thanks,
ScanCare

I keep getting a Twain error, how do i get it to work?


The Twain driver is used to scan images into the computer.
It is either corrupted or deleted.
Reinstall the Canon scanning software, it includes the Twain driver.

I have a fujitsu 4120 scanner that will not pull the paper even after i changed the roller and pad.


Hello,

Does the scanner displays any error message on the scanner panel? Is there any TWAIN error message?

If paper jam occurs, U1 error will be displayed on the scanner panel and TWAIN driver will display " Paper jam the ADF (Code DS32002)" error message.

This error is detected when one of the followings occurs:

1) A document does not reach the TOP sensor while the scanner has transported the document about 250 mm to pick. (The scanner
performs retry operation.)

2) The trailing edge of a document does not reach the TOP sensor after the scanner transports the document by the length (L) below. (The document may have slipped on the rollers) Scan condition Transported length.

In order to assist you with your scanner issue, Please provide the issue details with error message.

If nothing is being displayed, then the issue could be due to failure in Pick Motor function or Pick Sensor malfunction.

Hope the above information is helpful.

Thank you for contacting FixYa.

Downloading software (Twain??)


The download website for your scanner is here:

http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=351&modelid=8008

A TWAIN driver is simply a generic scanner software driver that your specific Canon software can hook into and use.

I recommend starting with this one and see if it installs the TWAIN driver you need:

"CanoScan Toolbox v2.2.3 for Windows 98/Me/2000/XP"
