PAPER SENSE SETTINGS
58
PAPER SENSE 1: Polarity
0 A low input on PAPER SENSE 1 is True
1 A high input on PAPER SENSE 1 is True
PAPER SENSE 1: Level/Edge sensitive
0
Level sensitive: PAPER SENSE 1 State bit (in Status
Register) is set to a 1 if PAPER SENSE 1 is currently
True.
1
Edge sensitive: PAPER SENSE 1 State bit (in Status
Register) is set to a 1 if PAPER SENSE 1 has been
True since the last time the Status Register was read.
PAPER SENSE 1: Stop Scan
0
Transitions on PAPER SENSE 1 will not clear the
scanning bit.
1
A False - to - True transition on PAPER SENSE 1 will
clear the Command Register and stop the scan.
PAPER SENSE 2: Polarity
0
A low input on PAPER SENSE 2 is True
1
A high input on PAPER SENSE 2 is True
PAPER SENSE 2: Level/Edge sensitive
0
Level sensitive: PAPER SENSE 2 State bit (in Status
Register) is set to a 1 if PAPER SENSE 2 is currently
True.
1
Edge sensitive: PAPER SENSE 2 State bit (in Status
Register) is set to a 1 if PAPER SENSE 2 has been
True since the last time the Status Register was read.
PAPER SENSE 2: Stop Scan
0
Transitions on PAPER SENSE 2 will not clear the
scanning bit.
1
A False - to - True transition on PAPER SENSE 2 will
clear the Command Register and stop the scan (after
the number of lines specified in the Lines to Scan
after PAPER SENSE 2 trips register).
