The position of each cassette is dependent on the paper length to be processed.
The cassette with the shortest paper needs to be mounted first because the
distance between the pick-up rollers of the cassette and the push rollers inside
the printer is the shortest at position '1'. For example, if envelopes are to be
processed cassette type B needs to be cassette '1'.
Cassette Position Minimum Paper Length
1 (first mounted) 104 mm (4,08 “)
2 200 mm (7.87 “)
3 (last mounted) 290 mm (11.42 “)
