4-1 PREVENTING AND SOLVING PROBLEMS
Please read this section before you have a problem.
PROBLEM:
Laminated images are curling up or down.
SOLUTION:
Excessive supply roll tension causes the laminated image to curl
up. This curl can be strong enough to prevent the item from hanging straight. It
can even pull a mounted image off the substrate.
PROBLEM:
Laminated images are exhibiting opposite corner curl.
SOLUTION:
See the above solution and reduce supply roll tension. Opposite
corner curl comes from stretching the film too much.
PROBLEM
: No power is getting to the laminator.
SOLUTION
: Make sure there is power at the electrical outlet being used, and
make sure both ends of the power cord are firmly engaged. The fuse (3 amp) is
located on the back right housing, but dead outlets and loose power cord
connections are the most common causes of this problem.
PROBLEM:
Tenting of the film on the image.
SOLUTION:
This has nothing to do with the film or the laminator. It’s caused by
various contaminates on the surface of the image. Use cotton gloves or a tack
rag as appropriate to clean your image just before it is laminated. If your system
is not in a fairly clean environment, close off the area and filter the air or... move
the system.
Supply roll tensioning systems dependent on friction between the cardboard film
core and the supply roll mandrel and/or tension collars can also create dust in the
environment.
PROBLEM:
The laminated material seems to have a pitted surface or irregular
surface that does not match the texture of the paper being coated.
SOLUTION:
This is usually caused by adhesive build-up or dirt on the rubber
rollers, but may be caused by debris stuck to the rollers, such as a piece of
paper. Inspect the rubber rollers and if they need cleaning, refer to section 5-3.
Irregularities in the surface of the film can also be caused by cuts or other
damage to the rubber rollers.
