4. Compress the assembly, taking care to align the pressure head tracking pin through the
pressure head tracking screws. If they are misaligned it may damage the nylon tips on the
tracking screws. (Fig. 5) While the assembly is still compressed, refit the pressure adjuster
wheel. (Fig. 6)
CAUTION: Care must be taken when compressing the spring.
5. Loosen the two locking screws which fix the position of the pressure head tracking screws.
(Fig. 7)
NOTE: Do not completely remove the locking screws as there are very small
nylon pads under them to prevent damage to the pressure head tracking screws.
6. Adjust the pressure head tracking screws in and out to rotate the pressure head lower section
independently from the pressure head upper section. (Fig. 8 & 9) The pressure head tracking
will be set once the marks on the two halves of the pressure head align. (Fig. 10) Once this
is set correctly, make sure that both tracking screws are in contact with the tracking pin then
tighten the locking screw which holds the tracking screws in position. (Fig. 11)
NOTE: The
tracking screws must be in firm contact with the tracking pin, but not so much that it
causes the operation of the pressure head to be excessively stiff.
7. Check the condition of the pressure head axle. The surface of the is axle clear of scores or
evidence of bearing slip, if the surface is in any way uneven the axle should be replaced.
Apply some anti-fret compound to the surface of the axle, (Fig. 12) in preparation for
reinstallation.
8. Check the condition of the surface of the pressure wheel. It should be worn evenly and free
of scoring or flats.
IMPORTAINT:
if the surface of the pressure wheel is damaged in
any way it will have to be replaced. Failure to do so will have a serious effect on how
the paper tracks in the machine resulting in an inaccurate cut.
Using a little anti-fret
compound or grease, stick the two shims
(one on each side)
to the bearings of the pressure
wheel. (Fig. 13) This will make reinstalling the pressure wheel much easier. (Fig. 14)
9. Insert the pressure head axle, ensuring that the flats on the axle align with the screws that
locate and adjust the axle. (Fig. 15 & 16)
NOTE: Position the axle approximately central
in the slot; this will be accurately set once the assembly has been refitted.
10. Refit the pressure adjuster wheel retaining screw.
11. The pressure and camber adjustments on the pressure wheel still needs to be set, this can
only be carried out when the assembly has been reinstalled in the machine.
