As the item is drawn into the laminator, you will need to
use both hands to stretch it back and hold it flat.
Some materials will be more prone to buckling. During
thermal lamination, some materials will require very firm
stretching as they expand with heat. Thicker materials
will not require so much.
If the leading edge of the item was not fed in evenly, a
lot of stretching will be required.
If you are using thermal
laminating, turn on the cooling fans before beginning.
As the item is drawn into the laminator, you can switch the machine to `continuous’ mode, and take your
foot off the foot switch. Near the end of the item, be sure that it stays flat as the tail end feeds into the
rollers.
If you are laminating multiple items, pick up the next item as the last item finishes feeding into the
rollers. Leaving a small gap between items, feed the next item in as described above.
If you are laminating large items, be sure that they do not crush one another as they leave the machine.
You may need to have an assistant separate the items as they leave the machine and lay them flat.
If all is going well, you should have now laminated your first items. If you have experienced a problem,
please consult the troubleshooting guide,

Film tension adjustment - Thermal film
Film tension should never be a difficult matter. A good quality film will require little braking. A poor film will
require greatly increased braking pressure.
The three rules of brake pressure are :
Brake pressure is increased by turning the tension knobs clockwise, and is reduced by turning them
counter clockwise. When adjusting pressure, you should only adjust by a quarter turn at a time.
Upper and lower brake tension should be even. Film will curl towards the greater amount of brake
pressure, so film that curls upwards means that there is too much brake pressure on the top roll.
Cut a semi circle shape into a piece of laminated film. This will show the film tension
The best amount of brake pressure is the smallest amount needed to acquire a good result.
More brake pressure is not necessarily the answer.
You must always be able to turn the film rolls with one hand, feeling only light to firm resistance.

Cut curls down :
Increase upper tension or
Decrease lower tension
Cut curls up:
Decrease upper tension or
Increase lower tension
