opposite the black supply roll knob on the supply roll
assemblies.The small spring pin that holds the hex adaptor
in place may have sheared,making it impossible to get any
tension on the supply roll mandrel.If so,it’s best just to call
your dealer or Ledco and replace the whole supply roll
assembly.Tension adjustment will then be restored and
wrinkling eliminated.If after following these troubleshooting
tips and following the basic procedures spelled out in the
owners operation manual you are still experiencing
excessive wrinkling(especially if more pronounced on one
side or the other),the problem may be more rubber roll
pressure related and you should now contact your dealer,a
servicing dealer/technician,the Ledco service dept. or move
onto the next,Intermediate, troubleshooting level.
Waviness in a laminated piece is usually a symptom of to
much heat,running the prints to slow or not using the cooling
fans.As the operation manual points out,the cooling fans
should be used when laminating any film over 1.5 mil thick.
Simply engage the fan switch before running the print
through the laminator.If the fan switch doesn’t light up or if
one or more of the fans fails to rotatate upon engaging the
switch,consult your dealer to check the switch and/or the
fans and wiring thereof.Or you can proceed to the next,
Intermediate troubleshooting level.

When troubleshooting excessive wrinkling
and/or steering problems,uneven or inadequate rubber roll
pressure may be the culprit.In order to determine this,one
must become familiar with the “dwell line’.The dwell line is
the imprint,or footprint,that the two front,laminating rubber
rollers leave in the web of threaded and heated laminating
film.To measure a dwell line,thread the laminator with some
