Example 2
• Paper Size: 00110000 A4 
• DF Open: 0
Example 1 indicates that the paper size and its orientation is "8

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].
