I have version 2.18 of iscan package.

RPM Installation:
    5  rpm -ivh libtool-ltdl-1.5.22-6.1.i386.rpm 
    6  rpm -ivh libtool-ltdl-devel-1.5.22-6.1.i386.rpm 
    7  rpm -ivh iscan-2.18.0-2.c2.i386.rpm 
    8  rpm -ivh iscan-plugin-gt-1500-2.1.1-1.c2.i386.rpm 

Please read your email and response to it. At end of email, I have included
the device options that I get using 
scanimage --help -d epkowa:interpreter:002:003
command. See that there are a lot of [inactive] options in it, 
though same functionality that is marked as inactive in it can 
be used using iscan.

This is a virgin installation of RHEL-5, with nothing but this scanner
No other software or hardware is installed.

Sorry for not including the device-info details in previous mail. I did not
access to the scanner at that moment.

Flatbed is usable with imagescan. When i take the device options with 
scanimage --help -d epkowa:interpreter:002:003 (see end of message to 
see details output of device options)

I get this
   Optional equipment:
    --source Flatbed|Automatic Document Feeder [inactive]
    --adf-mode Simplex|Duplex [inactive]
        Selects the ADF mode (simplex/duplex)

The source option has (inactive) at end of it. And if I still try to
mentioned the source using 
   #  scanimage --source Automatic Document Feeder 
I get error message telling me option is not active.
Meanwhile, I can still successfully use imagescan with flatbed and iscan
with both flatbed and ADF.

here is the detail of 
# scanimage --help -d epkowa:interpreter:002:003 

Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write PNM image data to
standard output.

    --batch-double         increment page number by two for 2sided originals
                           being scanned in a single sided scanner
