PROCEDURE FOR CLEANING / REPLACING THE PHOTOSENSORS
Use a jet of compressed air from a spray can to blow accurately through the paper insertion slot to remove any dust
from the photosensor units for document presence/alignment. After opening the upper structure, blow into the
optical fibre zones, pointing the jet of air inside the paper passage area to remove any dust that may be present in
the optical fibre nozzles.
