You may have tried to install Epson TWAIN using the Setup utility for the Adaptec AHA-1510 SCSI Host Adapter when you were using another Adaptec host adapter. The Epson TWAIN SCSI installer installs SCSI support only for the Adaptec AHA-1510 SCSI Host Adapter. If you are using a different adapter, follow the software installation instructions in the adapter user manual. Then run the Epson TWAIN Setup program and select Use Existing SCSI Support Software at the SCSI Interface Options screen.

An error condition may have caused your application or the TWAIN Source Manager to stop working correctly. Save any documents in process, close any open applications, and exit Windows. Restart Windows to restore the TWAIN Source Manager, then start your application and try again.

Target Device or Scan Mode names or settings are different or incorrect.

You may have connected a different model scanner than you were using when you defined the Target Device or Scan Mode. Delete or modify the settings to match your new scanner’s capabilities.

The scan is not the full width you selected in the Preview area.

The Epson ES-300C scanner restricts the scan width to 4096 pixels at high resolutions. Choose a lower resolution for a wider scan.

Numbers you type in the width or height box are not accepted.

Check that the value you entered is not greater than 8 inches wide and 11 inches high (14 inches if the Automatic Document Feeder option is installed).

If you are using the optional Transparency unit, values greater than 4.5 inches high and 4.5 inches wide are not allowed.
