Guide Plates, Dismantling:
The upper guide plate is threaded onto the LSS unit and held to the
lower guide plate by a pin and a snap-lock. To remove the upper
guide plate, just pull it straight out.
The lower guide plate is held in place by two studs, that fit holes in
the inner gable of the print unit, and a snap-lock, that fits a
rectangular hole in the lower outer gable. To remove the guide plate,
press the snap-lock with e.g. a coin or screwdriver and lift the outer
end free before carefully pulling out the guide plate.
Guide Plates, Cleaning:
The rectangular areas with a smooth surfaces on each guide plate
are actually windows, which are transparent to the light emitted by
the LSS. These areas must be kept free from dust, stuck labels and
adhesive residue. Only use isopropyl alcohol for cleaning.
