Hi,

I have a Royal 80MX paper shredder that won't shred (go forward), it
goes backwards fine so the motor etc. are working OK. This just
happened suddenly last week. It's as if the paper detection circuit
doesn't recognize paper being inserted. I took it apart and their is a
small plug in connector on the main circuit board with 4 wires leading
to a small trianglular shaped component (numbered only 0321, which may
be a date code for all I know) with two wires going to each of what
looks like 2 small blue plastic lenses. I assume that when paper is
inserted a circuit (of light?) is broken telling the machine to turn
on and shred in automatic mode. I found nothing on the other side of
the paper entrance, so maybe it bounces light off of the chromed
roller. Anyway, getting a replacement part will be impossible, but...
if I knew how this actually worked I could maybe short out the sockets
on the main board to make it think/detect there is always paper in it
so it would always work, then I could just turn it off to stop it, and
turn it on when I wanted to shred.

Any thoughts?

TIA!
