4.2.4.6.1 Disassembling the ASF
1. Remove the ASF assembly. (Refer to
2. Remove the brake lever, releasing one arm of the torsion spring
41.2 from the hook of the ASF frame. See
3. Remove the shaft fixing clip from the right side of the ASF drive
shaft. To release the clip, insert a small flathead screwdriver into
one of the slots next to the locking tab on its side. Then gently pry
the locking tab up and pull the clip loose from the ASF drive shaft.
4. Remove the right hopper release cam.
5. Grasping the blue paper guide, move the left ASF roller to the center
of the ASF.
6. Remove the white plastic spacer clipped around the drive shaft next
to the left hopper release cam.
7. Push the drive shaft to the left and remove the opto-interrupter
wheel after releasing the hook that holds it in place on the shaft.
8. Disengage the hopper assembly from the 2 pins on which it pivots
(left and right) at the top of the ASF frame.
9. Move the drive shaft all the way left, until it comes out of the hole in
the right side of the ASF frame. (This should free the right roller
assembly, which you should now be able to wiggle around.) Lift the
right roller assembly so that the drive shaft is just visible over the top
of the frame, and then free the shaft from the left side of the ASF by
sliding it out to the right. Remove the shaft.
(During reassembly, the compression spring on the right ASF roller
should be compressed to enable the hopper latch (see
to pass through the hole in the ASF frame.)
Section 4.2.4.6.)

During disassembly and assembly of the ASF, do not let
C A U T I O N
grease on the cams touch any other parts. Wipe off any
grease smeared on other parts.


The hopper release cams and the ASF rollers are
C H E C K
P O I N T
keyed to prevent you from installing them on the drive
shaft in the wrong direction.


Test the shaft fixing clip and opto-interrupter wheel to
make sure they're installed securely and don't slip off.


Note that the black roller assembly goes on the right
side and the lighter-colored one goes on the left.
