If you're using iscan, then it's an arguably stupid limitation in the
frontend.  If you also hit this when using other frontend let me know
what

  $ SANE_DEBUG_EPKOWA=10 scanimage 2> perfection-4490.log

barfs into the perfection-4490.log file.

There should be a list of the resolutions that the device claims to be
able to handle.

It could be that 4800dpi requires different main and sub resolutions,
something neither the epkowa backend nor the epson backend support at
the moment.

Hope this helps,
