 It looks like the Paper Out signal goes into J3-6 of
the keyboard assy. and
goes into the main logic board on J2-AA/BB; the main board test point is
TPZ17. It looks to be lo true judging by the pullup resistors. 
Looks right, IIRC, the microswitch is tied to ground.

...
 it goes into E37 pin 12 (7474) and comes out on pin 9
as MPC8 Ready H. 
Ok, that's what I needed to know, I'll have a play in that area, I think we
have a stuck
output here.

...
 test point is TPV20. I might add that the logic board I
am looking at is the
...
 M7728. I can scan in that portion of the schematic if
you need it. 
Ok, thanks, that would be great.   I'll don't recall offhand the main board
id, I'll have a look later today.

Kindest Regards
