Interchangeability:
(1) When old and new parts are not mutually interchangeable, use additional parts or an assembly part as indicated in "Parts needed for replacement by new part" to
install the new part.
(2) The mark to the left of the slash indicates whether the old part can be used in the new machine, and the mark to the right indicates whether the new part can be used
in the old machine. x = Not interchangeable o = Interchangeable
MODIFICATION BULLETIN NO. 7 Page 2 of 3 ISSUED ON: September 30, ’91
DETAILS OF MODIFICATION
To ensure the original separation, we found that it is more effective to increase the angle ( θ) as shown.
These are the modifications on production machines to change the angle from θ1 to θ2 :
1. The friction roller has been removed.
2. The mylar on the friction belt has been removed.
3. The dimension of the friction belt has been changed.
