I am trying to repair a Canon FC-3 photocopier.

The copy goes through the feeder area, the copyboard moves, a copy is made,
then...the paper jams in the copy outlet area and does not make it through the
rollers.

The problem arose because a heavy book was placed on the photocopier.

I've dismantled the copier and checked that there is not a blockage and cleaned
the output rollers with a dry cloth.

I simply can not work out what is causing the problem. I'd be very greatful if
you could suggest what I might try next.

Many thanks
Paul Wigham
