Target Device Or Scan Mode Names Or Settings Are Different Or Incorrect; The Scan Is Not The Full Width You Selected In The Preview Area; Numbers You Type In The Width Or Height Box Are Not Accepted - Epson ES-300C User Manual

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.
