Laminate position adjustments

Skew is caused by misalignment of the laminate cassette relative to the left-right axis of the printer, looking down on the printer from above. The skew adjust screw causes the pocket to rotate relative to the left-right axis. The vertical offset adjust screw controls the depth of the cassette in the pocket. Note that the front ear of the latch must be in close contact with the cassette, without changing its position.

Making sense of the skew adjustment

Turning the skew adjust screw clockwise rotates the cassette itself clockwise, looking down on the printer. On the face of it, that Laminate patch should worsen the condition motion shown in diagram A. It doesn’t do so, because the laminate patch is reversed in the transfer process.

Reset the cassette pocket

If the pocket has been replaced, or if the laminate is grossly misaligned. Back off the vertical offset adjust screw, skew adjust screw, and cassette latch adjust screws. Using three CR-80 cards [total thickness 0.090" (2.3 mm)] as a feeler gauge in the gap between the pocket and back plate, adjust for skew and vertical offset until the gap is an even 0.090" across the width of the pocket.

With a cassette in the pocket, adjust the latch screw so that the latch’s front ear is snug to the cassette, but doesn’t shift it out of position (see page 6-1). The pocket is now in its default position - as assembled in production before adjustments in final test.

Upper cassette skew adjustment procedure

The following procedure assumes that the horizontal offset has been software corrected as described in Section 5.

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 direction of skew. 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.
