The APS (auto paper select) sensors are arranged as shown in the diagram.
- Reading the Data -
Example 1
Paper Size: 11000000 8
1
/

x13 
DF Open: 1
Example 2
Paper Size: 00110000 A4 
DF Open: 0
Example 1 indicates that the paper size and its orientation is "8
1
/
2
x 13 SEF," and that the
document feeder (or platen cover) is open. Example 2 indicates that the paper size and its
orientation is "A4 LEF," and that the document feeder (or platen cover) is closed.
The "Paper Size" data starts with eight digits. The first digit indicates the output of L2; the second
digit, L1; the third digit, W2; and the fourth digit, W1. The other four digits (from the fifth through
the eighth) are always "0000." In Example 1, the APS sensors L2 and L1 detect paper (W2 and
W1 do not).
In Example 2, APS sensors W2 and W1 detect paper (L2 and L1 do not). The paper size and its
orientation is based on the outputs of these four APS sensors.
The "DF Open" data shows "1" or "0," indicating if the document feeder (or platen cover) is open
or closed respectively. The data is based on the output of the platen cover sensor [A].
