9 Operator Maintenance
9.1 Cleaning the sensors
The optical sensors consist of two halves: emitter and receiver. These can become
obstructed due to paper dust and should periodicaly be cleaned using a non-
flammable airduster. Both halves must be cleaned.
This section shows where the sensors are located. For most sensors, an indicator
arrow is pierced showing you where the jet of the airduster should be directed. For
some sensors, the retaining bush is visible next to the lens: ensure you spray into
the lens, not the bush.
Insertion head
Sensors are retained with a bush next to the lens: where this is
visible, ensure that you spray into the lens (arrowed), not the bush.
Direct the airduster into the openings arrowed and spray liberally.
Open the perspex top
cover and raise the collate
clamshell (closest to the
envelope hopper) so that
it locks in place.
Picture shown is viewed
looking inside the collation
area towards the envelope
hopper.
