HeatSeal Sprint H925 - Lamination Tips
for Optimum Performance
TM ®
Minimizing potential heat lines on media
Depending on the ambient temperature, media type and film thickness the HeatSeal Sprint H925
may produce a heat line on the initial 3 to 5 sheets of output. Follow the below recommendation
to minimize the likelihood of experiencing heat lines:
Recommended morning start-up routine:
Turn the main power switch to the “ON” position.
Additional tips:
Film thickness can make a difference and 1.7 mil film may produce more of a heat line than
3 mil or 5 mil films.
If your machine has not been used for several hours, it may be “cold” again and the morning
start-up routine is recommended to be repeated.
Media and inks can make a difference and darker images or glossy papers may produce more
of a heat line than other medias.
For best results, do not operate this machine in an environment with an ambient temperature
less than 72°F/22°C.
Operating at a lower than normal room temperature, prevents the nip rollers from reaching the proper laminating
temperature, resulting in faint heat lines across the finished sheet.
Load two or three sheets of plain paper into the feed tray.
Press the start button.
Test one single sheet of your special media.
Allow the machine to run the start-up sheets and stabilize its temperature for at least 5 minutes.
If required, repeat steps 4 and 5 again until the heat line is no longer visible.
HeatSeal Sprint H925 - Lamination Tips
for Optimum Performance

IMPORTANT: When laminating media that has been 3 hole punched, load that media in with the
holes down into the machine first. Failure to do so will result in mis-cut sheets due to the sensor
picking up a hole as the end of the page.
The composition and quality of any type of media/paper can change at any time. GBC cannot specify nor
guarantee the performance of any specific brand, type or manufacturer of media/paper. Even standard media
can change from time to time due to circumstances that cannot be controlled by GBC.
Successful lamination tips:
Prior to use, media should be allowed to acclimate at least 48 hours in the environment in which
it will be used. Optimum storage and operating environment is between 70°-80°F with 50%
relative humidity.
Upon completion of a lamination run, do not leave unlaminated media in the feeder tray.
Media should be removed and stored in a way that it is stacked flat and in the proper
environmental conditions.
Always ensure that the media has the straightest possible path into the laminator. If laminating
a longer length of media, it is not recommended that the media is draped over the back of the
feeder tray, as this may cause the feeder to not pick the sheets properly.
Allow ink on printed media to properly dry prior to lamination.
DO NOT load any type of media that is creased, folded or not square into the feeder as this
may cause the unit to jam.
