8.5 Belt Adjustment
Pressing Roll Belt
Oversized holes allow the position of the stepper motor relative to
the bracket to be adjusted so the tension of the belt does not become
too tight, causing unnecessary wear. Rotate the gear wheel 1/4 of a
turn at a time and check that the gear wheel and pressing roller can
be rotated freely by the belt, which should flex just a little when you
press it with your finger.
