Step 9 - Adjust the Tamp Pad Position
Goal:
Slide the tamp cylinder module across the dovetail track to the correct position in front of the
printer, this will be approximately 1/8th of an inch from the peel blade edge.
Goal:
Align the tamp pad height to the peel blade feed position; this should be close to 1/8th of an
inch below the peel blade edge.
Goal:
Adjust the tamp pad closer to or further away from the baseplate to align the label to the pad.
This position should allow a column of vacuum holes to be covered, while triggering the label
present sensor.
•••• Sub-Step (a) ••••
Loosen the two dovetail track screws [A] (1/4 inch socket-
head cap screws) and slide the tamp cylinder assembly
into a position that gives approximately 1/8 inch gap
between the peel blade edge and the tamp pad. Once in
position, tighten the dovetail track screws firmly.
•••• Sub-Step (b) ••••
Loosen the tamp cylinder mounting screws [B] (1/4 inch
socket-head cap screws) and slide the tamp cylinder in
and out from the baseplate to align the label with the pad.
It is important that the label dispensed covers the ported
vacuum holes and covers the label present sensor (if
equipped). These screws adjust the tamp pad height, in
relation to the peel blade edge. Before locking the screws
in place from adjusting the in-and-out position, set the
height. The labels are optimally transferred to the tamp
pad when the pad is 1/8th inch below the peel blade edge.
This keeps any label curl at the end of the label from
landing back on the peel blade edge. As the label’s
adhesive is exposed to air, the tendency is to shrink, or
curl away from the tamp pad. Some curl at the end is
expected, and by keeping the pad below the peel blade
edge, labels curling back to the liner will be avoided.
Once the pad has been adjusted, tighten the screws and
apply air pressure to the system and re-check the tamp
pad position. The adjustment of the tamp cylinder’s air
cushion will effect the resting height at home of the
cylinder, and thus the tamp pad. Be sure to check this
height again, after all pressures and adjustments to the
tamp system are complete. If the position looks correct,
tighten the mounting screws firmly.
