Scrunched Paper on Canon PC-20 Copier
 

The paper goes askew just before it goes through the heat roller.
With the paper tray to the left, top open, you can see a small black
pinch wheel (about 5/8" in diam by 3/16" wide) back and to the left,
to the right of the heat roller, and just forward of what looks to be
some sort of guide ( a flexible plastic strip about 3/16" wide and 3"
long with a small spring at one end. I would assume the edge of the
paper is supposed to run under the strip and then go under the pinch
wheel, but instead it seems to be cocked at a slight angle so it
sometimes misses the pinch wheel. It is then crooked before it goes
under the heat roller and so gets wrinkled there.
This does not happen on each pass, some are O.K. Also the
image on the paper is complete, the trouble occurs just before it
gets fused by the heat roller.
Any ideas as to why the paper shifts slightly and misses the
pinch wheel. It appears to me that it wouldn't have to be much
out of alignmnent as the wheel is quite narrow and only mates
with the far edge of the paper. (There is no pinch wheel for the
other paper edge.)
Your help is very much appreciated!

P.S. Please let me know if the paper path is not what I think
it is.
Although very old, this has been a great copier and has been
amazingly trouble free, so I'm hesitant to dump it!

i think you will have better results with a computer oriented group...
people here will certainly answer, but answers arent always solutions...
