4.10.4.8 Cassette Pocket Reset
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 like this if the pocket has been replaced, or if the laminate is
grossly misaligned.
Step 1. Back off the vertical offset adjust screw, skew adjust screw, and cassette latch
adjust screws.
Step 2. 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.
Step 3. With a cassette in the pocket, adjust the latch screw so that the latch’s front ear is
snug to the cassette but does not shift it out of position.
The pocket is now in its default position -- as assembled in production before adjustments in
final test.
