<How to Read Sensor Information>
• Convert the numerical value of the hexadecimal number printed on [ELEMENT DATA]
into the binary number, it compares with the allocation of each BIT, and the status of the
sensor is confirmed.
ex. When Sensor Information1 is displayed as 0x0005.
1. Convert four end digits “0005” of 0x0005 into the binary number (14 digits).
2. The BIT number is allocated in converted value “00000000000101.”
(BIT0 to BIT13 is sequentially allocated from the first digit.)
3. In this case, because BIT No. “0” and “2” become “1”, so it can be confirmed that the
Tray 2 Device Detection Sensor is “In position” state and the Tray 2 Paper Near-Empty
Sensor is “Blocked” states from the Sensor Information table.
