These can feed up to 100 envelopes at a time through the straight paper path.

To a sheet of paper, a paper path is like a Tough Mudder — a multistage obstacle course that must be run in hostile conditions.
Warner pointed to the back of the paper path, where the fuser was situated: a set of black rubber rollers heated to three hundred and eighty-five degrees.
The holy grail of printing — a paper path that incorporated composition, and so could produce different pages, one after another — remained inconceivable.
Caressed by sultry secretaries in advertisements, it resembled an instrument console from the Starship Enterprise and shipped with a fire extinguisher, in case its heating elements set the paper alight; seven plain-paper copies per minute trundled through its paper path.
