IIRC, the only spinning disks in the 1419 all had little rubber tires on them and were used to move the paper through the machine.
IIRC, the only CCWs the 1419 understood were "Read Backward", "Select
Stacker" and "Disengage".

Perhaps it took too long to stop the spinning disk and start spinning it
the other direction.
I was not aware that a Magnetic Ink Character Reader, as in the original
post, had any spinning disks inside. What were these disks used for? I
