C. Main tray paper detection
The tray upper limit sensor (PS2) and the stapler paper exit upper limit sensor (PS7) maintain the distance
between the upper surface of the paper exited in the main tray (or the main tray upper surface when no paper is
exited) and the paper exit opening at a specified distance to prevent any uneven paper exit from occurring.
While in the continuous print mode, the FS uses a software to count the number of sheets of paper exited and
stops printing when the count reaches the maximum number of sheets loadable for each paper size.
However, when paper has been exited is removed while in printing, the tray goes up to turn ON the counter
reset sensor (PS15). This resets the software counter, thus allowing paper to be exited without limit.
The tray lower limit sensor (PS3) detects the lowest limit of the tray. In the intermittent print mode, the total num-
ber is not added up by the software counter and the PS3 is used to restrict the number of sheets of paper.
