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.

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.

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.

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.
