3.Referring to Section 2, Media Handling, 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 - VERY IMPORTANT! Set the cassette aside.

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 skew adjustment you are about to make.)

5.Using a fibertip pen mark the skew adjust screw head for reference.

Note • One full turn of the screw de- skews the laminate by approximately 1°, equivalent to 0.03".

6.Using a 7/64" hex wrench turn the skew adjust screw in ¼ turn increments as directed in the diagram below.

7.After each movement of the skew adjust screw do the following three actions:

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

b.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.

c.Print a test card and inspect for skew.

8.Re-install the cassette.

Lower cassette skew adjustment procedure

Once the front surface skew is consistently acceptable, inspect the back surface patches of the last few cards to pass through the laminator. Note the direction of skew on the back surface. (Don’t worry about vertical offset at this stage unless the laminate overhangs grossly, in which case proceed to the Vertical offset adjustment procedure, below.) When

flipping the cards for inspection, keep the mag stripe (if present) toward you.

Flip the cards left to right (not front to

back)

Correct for skew in the lower laminator using the same procedure as the upper cassette, but note that the “reel in” direction will be clockwise for the lower cassette as it sits in the printer.

After each movement of the lower cassette skew adjust screw, perform exactly the same three actions described in step 7 of the upper laminator.

Upper cassette vertical offset adjustment

The following procedure assumes that the horizontal offset has been software-corrected and that skew has been adjusted as outlined above.

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.

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.

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.

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.)

5.Using a fibertip pen mark the vertical offset adjust screw head for reference.

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)
