I don't remember it being non-standard.
The paper is 8.5" wide including the tractor holes, whereas normal
paper of that size is 8.5 plus the tractor holes so that once the
tractor edges are removed (they are usually perforated), the remaining
paper is 8.5 wide.

We had one in college, in 1974. We got rid of it as
soon as possible
because it was even less reliable than an ASR33. It would jam
constantly. Sometimes it was the head jamming on the paper, sometimes
it was the head jamming on the carriage. Also, it had the worst
keyboard I ever saw; it too tended to jam.
We replaced it by an LA36, which was faster, and utterly reliable.
