C.

Identifying the Cassette Size

The presence/absence of a cassette in the cassette holder and the size thereof are identified by
four switches (CST1 through CST4) provided in each cassette holder. Based on the combinations
of the switches which have been actuated, the microprocessor recognizes the presence/absence of a
cassette as shown in Table 5-101 and, at the same time, determines where to reverse the scanner
and how to control the blank shutter.
