T. PRINT FORCE- TOP TO BOTTOM:
If the force is not uniform from the top to the bottom
of the typeface, the printed image will not be
uniform. Verify that the typeface is being inked
properly before proceeding.
For the band printer , check that the top of the
band-head has been rotated against the spacer
(Figure 3.18). If needed, the spacer can be moved
slightly on its mounting screw.
The block printer can be tipped by loosening the
nut on the printer block mount shaft (Figure 3.19).
When the shaft is positioned properly, retighten the
nut. Check to see that the printer block can be
removed and replaced easily.
U. PRINT FORCE RANGE:
Figure 3.21 and 3.22
THIS PROCEDURE SHOULD ONLY BE PERFORMED
BY SOMEONE WHO IS QUALIFIED TO WORK IN THE
PRESENCE OF CHARGED ELECTRICAL CONTACTS
AND UNGUARDED MACHINERY.
The print adjust knob has a limited range of
adjustment. It can be rotated clockwise (decreasing
printing force) until it will not turn any further when a
moderate torque is applied. It can be rotated
counterclockwise (increasing printing force) until the
turning resistance abruptly decreases, at which time
turning the knob further will have no affect on the print
force. The full range is about 2 1/2 turns.
If the range is more limited, the printer adjust arm is
not moving freely against the lever. The two screws
on the printer adjustment arm need to be adjusted to
allow free movement with minimum space between
the lever and printer adjust arm. The screws are
secured with thread locking compound, so they will
not work loose.
Normally, good print quality should be attainable
near the mid-point of the adjustment. If not, first
verify that the type is being properly inked and that
the side-to-side print force is uniform.
DO NOT USE EXCESSIVE PRINT FORCE TO
COMPENSATE FOR OTHER DEFECTS.
To adjust the range of the print force:
1. Disconnect the power.
2. Remove the access cover from the side of
the closer.
3. Identify the printer cam bearing (Figure 3.22)
which is behind the stop cam. While looking
below the stop cam, manually press and
release the printhead. The cam bearing will
move as the printhead moves.
4. Jog the mechanism until the printer cam bearing
(Figure 3.22) is contacting the highest point on
the lobe of the printer cam (Refer to Part V, this
section).
5. Turn the print adjust knob clockwise until it
stops.
6. Turn the knob counterclockwise 1 1/4 turns.
7. Verify there is a closure in the print position.
8. Identify the printer arm pivot mounting screw
(Figure 3.22) on the motor mounting plate
attaching the pivot to the motor mounting plate.
(The pivot is behind the motor mounting plate).
Loosen the screw. As the screw (and pivot) is
moved up and down, the printhead will move in
the opposite direction.
9. Move the screw as high as it can go when
moderate force is applied and tighten it. Check
that the printhead is resting firmly on the
closure by pressing downward on the print-
head.
10. Replace the access cover.
11. Verify the proper print force is attainable within
the range of the adjustment knob by operating
the machine. Readjust as needed.
