4.10.4.6 Vertical Offset Adjustment (upper cassette)

Step 1. Check the action of the cassette latch. If necessary adjust its fore-aft position so that

its ears smoothly engage the cassette without nudging the cassette.

Step 2. Print and laminate a few test cards in the usual way, noting the vertical offset (front-

to-back position) of the laminate patch on the front of the card.

Step 3. Unlatch and remove the upper cassette from its pocket. Rotate the laminate core

counterclockwise, reeling in the laminate to bring it even with the lips of the

cassette. Set the cassette aside.

Step 4. Remove the upper transfer guide, then discard the laminate patch on the upper

transfer roller. (If you don’t do this, the next patch to be applied will not reflect the

vertical offset adjustment you are about to make.)

Step 5. Using a fiber-tip pen, mark the vertical offset adjust screw head for reference.

Step 6. Using a flat blade screwdriver, turn the vertical offset adjust screw in ¼ turn

increments as directed in diagrams below. NOTE: One full counterclockwise turn

of the screw pushes out the cassette, and therefore the laminate patch, by

approximately 0.03" (just under 1 mm).

Step 7. Re-install the cassette.

Step 8. Adjust the cassette latch screw in the same direction, by the same amount.

Step 9. If you have not already done so, remove and discard the laminate patch on the

upper transfer roller, close the printer cover, then press the

LAMINATE button to

run out a fresh patch from the upper cassette.

Step 10. Print a test card and inspect for vertical offset.

Step 11. Repeat Step 6 through Step 10 until the laminate is correctly positioned.

Note • The following procedure assumes that the horizontal offset has been software-

corrected, and that skew has been corrected.

To correct this condition turn the vertical

offset adjust screw counterclockwise

To correct this condition turn the vertical

offset adjust screw clockwise
