I have a number of i1220 scanners that need to be integrated with another application. This application looks for an installed twain driver but fails to find one in the case of the i1220. I have downloaded and installed standard driver which operates the scanner correctly from the devices area. OS is Win 7. system normally operates correctly for Canon DR series and a few other older scanners. Is there a twain driver for the i1220? Thanks, Brett

This is an issue with the Driver Installation, Get the drivers Uninstall and reinstalled from the CD.

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 TWAIN drive should be installed when one installs the actual "Drivers" for the unit itself, accordingly I provide you with the download link below.... look for and install ALL drivers and software, especially the Scan manager and TWAIN drivers....

What software are you using?
Have you installed the TWAIN driver for your operating system?

depending on the type of software you are using, this could be where the problem lies. test the scanner using the scan validation tool.
Start>All programmes>Kodak>Document Imaging>Scan Validation Tool - use the TWAIN driver.

If the scanner scans fine here, then this is software related and you will need to contact the software manufacturer to resolve the issue.

I think you mean TWAIN.

twain is a sub process that is used to make scanning easier between different applications.

Part of what you want to do depends on the application you are using to scan your document eg word, photoshop, etc etc.

Quite often when you install the software for a scanner it will ask if you want to install the twain components. You should click yes.

I would try to re-install the software for the scanner including any updated drivers from cannon support on the web.

Some applications may offer other methods besides twain to get yoyr scan. If you select one of those and try again.

Hope this helps

You need to download a "Twain Driver and Epson Scan Utility" from
the Epson Website.

But before you start downloading the Twain Driver we need to delete
the previously installed driver in your computer.

1.) Click and open the MAC or Apple Hard drive / Application and trash Epson Scan and Epson Scanner Monitor ( drag it to your trash )
2.) MAC hard drive / Library / Image Capture / Twain Data Source., we need to trash ( *.ds file )
3.) MAC hard drive / Library / Application Support., trash the Epson Scanner Module
4.) Disconnect the connection ( USB ) between the printer and your MAC.
5. ) Empty your Trash bin and restart your MAC

After the restart we can now download and install the Twain driver to your MAC.

After the installation try to launch Epson Scan under Application

If connected via USB, unplug cable and insert into another available port and error message should disappear.

The scanner can not be used with Twain.


3 TWAIN or ISIS® applications cannot be used directly.http://www.fujitsu.com/us/services/computing/peripherals/scanners/scansnap/s300.html

It looks like the computers have a hard time communicating with the scanner it will be advisable to download all the current firmware available, her is the link:
