I worked in a shop with <i>two</i> of these, side by side.  I don&#x27;t remember toner (except for the rare spillage) so much as the fog of thousands of tiny bits of paper dust.<p>It was generally a low-maintenance job: pull the printed stack periodically, separating individual jobs; every 20 minutes or so, feed a new box of paper and tape-splice new to old; separate individual jobs in the printed stack; listen to the gentle white-noise shuffle of paper swimming through the tracks.
