evidence of rapid wear from reading on the DEC optical reader. It does use
physical pins on the feed holes but on a big diameter wheel so more holes
are engaged. The limit is more often when something goes wrong. The most
common is it doesn't fold properly on the output side so either it dumps the
tape on the floor or it bunches up in the reader which can smush it up some.
If the tape gets a small tear in it that can jam the reader which can make
the tear worse or sometimes tear a feed hole. If the tape has been stored
poorly two folds can stick together and jam the reader also.
