Slackware is not officially supported and I don't think there has been

aged a lot (all distributions seem from 5 or 6 years ago).

That is the most recent set of packages for your scanner, so that looks
good. Were there any error messages when you installed? In particular
about unsatisfied dependencies?

Oops. Never mind the message, just about everything gets mapped to
that. "status(4)" is SANE_STATUS_INVAL.

Don't know yet. Could you provide the output of
SANE_DEBUG_EPKOWA=HEX scanimage >/dev/null
