SENSOR

12.1..... Sensor - All Machines

Sensor maintenance is dealt with in the operators manual and only
involves careful cleaning of both units and their lenses.

The sensors are mounted so that they are exactly aligned without
any adjustment so no provision is made to adjust them.

Sensor alignment can only be measured using an oscilloscope, but
if you suspect misalignment, first check that all fixing screws are
secure and that none of the relevant components are damaged.

When swinging the upper sensor assembly away from its mounting
take great care not to strain or trap it’s cable and if you are
clearing a paper jam avoid bending the input bed as this may result
in an excessive gap between upper and lower sensors.
