Thanks Alesh.  I previously owned an Artisan 700 and it developed the
same problem partway through the time I owned it.  I remember
upgrading the epkowa backend a couple times, so the problem may have
been introduced by one of the upgrades.

Do you know which version of the epkowa backend was the first to
support the 710?  Gentoo's package tree has 2.11.0 and 2.21.0.  2.21.0
exhibits the problem, but 2.11.0 doesn't seem to support the 710.  I'd
like to try the first version that supported the 710.
