Heating - GBC ORCA-I Operation Manual

Operation
+HDWLQJ
Use the following instructions when heating one or
both of the laminating rolls. The procedure is the
same for the top and bottom heaters.
1. Set the heater switch to ON.
2. Adjust the temperature controller for the desired
operating temperature using the temperature
controller push buttons.
3. When heating the rolls, keep the top roll down
and turning at a moderate speed to prevent
uneven heating.
4. It will take approximately 30 minutes for the
laminating roll(s) to reach operating temperature.
When the preset operating temperature has been
reached, the machine is ready to use.
5. The ORCA-I can be used for cold mounting and
laminating while maintaining the temperature of
the main laminating rolls by using the output
rolls as a laminator (by feeding prints from the
rear) for a quick change-over between hot and
cold laminating.

Always feed prints perpendicular to the laminating
rolls.

When installing or moving 51" - 55" rolls of film, the
hinge side of the roll could be damaged unless the
following steps are followed:
1. Lock core support to middle of the shaft. Lock
two core chucks on shaft ends, located to support
material a few inches from ends of the roll.
⇒ Note
Paper unwind may require two evenly spaced core
supports.
2. Place the roll on the unwind shaft.
3. Carefully close the unwind shaft, holding the roll
away from the hinge (to prevent pinching the end
of wide rolls).
