Air Cylinder Regulator

NOTE: You may also adjust the cylinder delay time through the Applicator

Delay menu. See “Applicator Delay Menu” on page 195.

The air cylinder regulator (CYLINDER valve) is used to regulate the air to the

applicator cylinder. The regulator setting affects how quickly the applicator

pad will extend (apply stroke) and return (return stroke) during the apply

cycle. This adjustment determines the force with which the applicator pad will

contact the product. If set too high, the applicator pad could contact the

product with enough force to cause damage. If set too low, the applicator pad

may not contact the product. The air pressure delivered for the apply stroke

and the return stroke is equal.

NOTE: Do not exceed 60 psi.

Monitor the setting of the air cylinder regulator using the PRESSURE gauge.

Air Jet Adjustment

The air jet adjustment (AIR JET) controls the air supply to the air jet tube. Air

is forced out the air jet tube allowing the labels to properly transfer over the

peel bar then to the applicator pad. If the adjustment is too low, the labels will

not properly transfer from the printer to the applicator pad. If set too high, the

label edge will be incorrectly positioned. The air jet is factory preset. Adjust

the air jet pressure by turning the AIR JET control clockwise to increase the

flow, counterclockwise to decrease the flow. See “Positioning The Air Jets” on

page 52.

Vacuum Adjustment

NOTE: You may also adjust the vacuum delay time through the Applicator

Delay Menu. See “Applicator Delay Menu” on page 195.

The vacuum adjustment (VACUUM) controls the amount of air flow through

the vacuum generator, thus determining the amount of vacuum holding the

label onto the applicator pad. A weak vacuum will cause labels to fall off of the

applicator pad prematurely. A vacuum that is too strong, however, can cause

difficulty when transferring the label onto the applicator pad and the product.

Vacuum is increased by rotating the valve clockwise and decreased by

rotating the valve counterclockwise.

NOTE: To get a vacuum on every label, every hole on the applicator pad

must be covered by the label surface.

Monitor the setting of the vacuum adjustment using the VACUUM gauge.

The minimum setting is 20 inches hg.
