The Label is fed toward the tamp pad as it exits the print engine. The liner is driven
around the peel tip of the printer. While the label dispenses off of the liner, it dives down
due to the angle at which it is dispensed, the close proximity of the tamp pad, and gravity.
An air assist tube is mounted slightly below the print engine (figure 4-7 and 4-8).
This fluted metal tube directs an airflow towards the tamp pads surface and as the label
crosses in front of the tube, it is blown back towards the tamp pad. This assists the label
in staying flat against the tamp pad as it is fed from the printer, until the vacuum of the
tamp takes control. Air assist is energized at a specific time (operator adjustable) after
the label has commenced feeding. Energizing the air assist to soon or too late can result
in poor label dispense, label placement on the tamp pad, and label placement accuracy
on the product.
