TROUBLESHOOTING
The following guide will assist you with most problems that may be encountered when laminating.
PROBLEM:
Laminator is inoperative. Motor does not turn, machine does not heat.
ACTION:
Unit may be unplugged. Connect power supply. Ensure that the circuit breaker
has not tripped Fuse may have blown. Replace fuse (rear next to power cord)
with 15 amp BUSS (MDA-15) for standard units.
PROBLEM:
Laminator heats but motor does not run
ACTION:
Ensure all motor switches are in the ON position. Check that FWD/REV switch is
up. (FWD) Change motor fuse with .75 amp fast blow fuse.
PROBLEM:
Laminator blows fuses often.
ACTION:
Ensure machine is running on a dedicated circuit. Do not exceed maximum
material thickness. Reduce supply mandrel tension.
PROBLEM:
Laminating film and item being laminated move through
laminator erratically.
ACTION:
Check thickness of item to be laminated. Maximum thickness is
1/16" (1.6mm). Clean rollers of residual adhesive. Refer to MAINTENANCE
section for cleaning instructions.
PROBLEM:
Plastic is not bonding to the item or to itself at the edges.
ACTION:
Make sure rollers are at proper operating
temperature and have had time to warm up. See Table 1 for the suggested
temperature ranges. (ensure you are using quality film). If the temperature is set
correctly and the film is not bonding then the film is most likely bad.
PROBLEM:
Wrinkles on laminated item running parallel with supply
rolls.
ACTION:
Increase film mandrel tension on top and/or bottom supply rolls; only
small amounts between tests. Reduce roller temperature.
PROBLEM:
Stretch lines appear on laminated items running parallel with
the outside edges.
ACTION:
Increase supply mandrel tension on top and/or bottom supply rolls.
Reduce roller temperature. Clean rollers of residual adhesive. See
MAINTENANCE section for cleaning instructions.
PROBLEM:
Blistering of the film appears over the item or along the
edge.
ACTION:
Reduce roller temperature. Clean laminating rollers. See MAINTENANCE
section for cleaning instructions. There may be moisture in the paper you are
laminating. Store paper in a dry place and be sure that any ink is thoroughly dry
before laminating.
