CONTROL to a slower setting or move the RUN/STOP switch to the “Stop
position until the Ready lamp illuminates.
More thorough heating of the heat rollers is achieved by allowing the motor
to remain off for longer periods of time. Operation of the laminator in the
Standby mode for thirty or more minutes may necessitate positioning the
SPEED CONTROL at or near the medium speed setting. For example,
satisfactory lamination quality is achieved using a single glossy poster
laminated at slow speed immediately after the Ready lamp has illuminated at
initial warm-up. The same poster’s ink may fade if immediately laminated
after the laminator were operated in the “idle” mode (power on, motor off) for
thirty or more minutes. Acceptable lamination can be achieved by increasing
the SPEED CONTROL setting which decreases the dwell time.
Operating the laminator in the “idle” mode (power on, motor off) for longer
periods of time facilitates continuous lamination of thick items. If several thick
items are to be laminated, it is recommended that the laminator remain in
“idle” mode for thirty minutes to attain maximum operating temperatures.
A simple method of checking whether or not the equipment is sufficiently
heated to laminate a particular material is to laminate test (scrap) material of
the same or similar type prior to feeding the material to be laminated. This
procedure is also recommended because rotating the heat rollers prior to
lamination will more evenly distribute the heat.
The following chart provides general guidelines for proper settings to use for
certain materials and laminating film combinations. This chart is only a
general guide. Different settings may be suitable as the warm up time,
lamination time and materials change.
