Composition/Operation
2.4 Cassette Type Detection
• The Paper Feed Cassette is provided with the Cassette Type Detection Switch.
• When the cassette is inserted into the printer, the switch pusher provided on the right-
hand side of the cassette pushes the lever according to the paper size, turning ON the
switch.
• The Cassette Type Detection Switch consists of three switches.
The combination of these switches that turn either ON or OFF allows the printer to deter-
mine the cassette type (paper size).
