Re-open scanner after each scan to work around HPLIP/SANE bugs
With recent versions of HPLIP and SANE, my HP OfficeJet 4500 doesn't
properly finish an ADF job. All images get returned, but the device is
still busy afterwards, refusing to scan anything else. Closing the
device finishes the job, allowing further scans after opening the
device again.
