Adjusting the Card Flattener
The Card Lamination Module provides an adjustable Card Flattener that allows you to fine-
tune the flatness of laminated cards. This flattener works by reverse bending cards as they
travel through the Laminator while they are still warm.
In most cases, card warpage is only a concern when laminating on a single side of card
stock which has a PVC-based core rather than a polyester-based core. Cards with a PVC-
based core are not as heat resistant and are not recommended for use when laminating
By default, the Card Flattener is configured at the factory to accommodate UltraCard III type
card stock. (Note: If you are experiencing an unacceptable amount of card warpage, please
refer to the following to adjust the Card Flattener.)
Step Procedure
1 Open the Front Cover of the Card Lamination Module.
2 The Card Flattener Adjustment Knob is the black knob on the left side of the
Laminator. Follow this instruction:
• If laminated cards are bowing downward, turn the Card Flattener
Adjustment Knob counter-clockwise. (Note: This creates more contact
between the Flattener Roller and the card in order to increase the reverse
bending pressure.)
• For best results, depress the knob and turn it 15 degrees, then print and
laminate a test card. Repeat this process as necessary.
3 If the card is bowing upward, the reverse bending pressure may be too great.
Follow this instruction:
• In this case, rotate the adjustment knob clockwise. (Note: Some card
types have very low heat resistance and may not be acceptable for
laminating.)
