Multiple labels feed from the Application Arm, with or without platform movement.
Calibrate the label sensor. (See Section 3.4.)

Label position on container varies, side to side, from container to container.
Make sure the label stock is running parallel to the Application Arm (See Section 2.1.12.) and the
Roll Guides and Guide Collars are close to, but not pinching the label stock. Make sure the
thumb screw holding the Container Guide in place is tight. Also, be sure to hold the container
tight to the guide until labeling begins.
Label position on container varies, top-to-bottom, from container to container.
Lower the Application Arm height. (See Section 2.2.) Change the Application Roller Position
and/or the label distance from the peel edge. (See Section 3.3 & 3.5.) The optimal roller/label
position is determined by the angle of the arm during application and the various properties of a
particular label/container combination. Experimentation may be necessary.
Leading edge of labels fold as they are applied to the container.
Decrease the label distance from the peel edge. Some thin polyester and polypropylene label
materials do not have enough stiffness and can droop down from the peel edge if the label
position is set too high. This can cause folding at the leading edge of the label. (See Section
3.3 & 3.5.)
There are bubbles or wrinkles in the label.
Wrinkles or bubbles can appear on the applied label if the container is not smooth or has bumps
or ridges. To minimize bubbling or wrinkling, adjust the Application Roller position and/or the
Label Position. (See Section 3.5.)
Container Platform is stalling, scraping, or squealing.
An Application Arm position that is too low or excess pressure on the Application Arm Push
Bar can cause the platform to stall. Roll Guides and/or Guide Collars that pinch the label stock
can also contribute to stalling. After checking and correcting these items, if the platform still
stalls or if scraping or squealing is detected, replace the Platform Bearing Plate. (See Section 6.2.)

Check for container taper. Some containers may have a slight taper that will cause the label
to be applied crooked. Make sure your container is oriented so the taper is from front-to-
back or back-to-front, NOT side-to-side. You may also choose to install a wedge on one side
or the other to make the container level from side-to-side.
Roll Guides should also be positioned very close to the roll, but not squeezing any part of it
(so the roll has very little, but at least some side-to-side play between the guides). For larger,
heavier rolls make sure that the roll is positioned on top of the Roll Guides with the magnetic
portions facing in. This will minimize the chances that the heavy roll will push the guides
out of place.
Make sure the Roll Drag Arm is in place as described in Section 2.1.4.
Make sure the label stock runs parallel to the Application Arm. (See Section 2.1.12.)
