Size detection control

For the size detection of a paper, there are the following two directions for each of the tray /Up and the tray /Lw:
that is, the main scan direction and the sub scan direction.
The size detection in the sub scan, when the PI paper set sensors /Up (PS44) and /Lw (PS45) [6] turn ON, is
made by the following 3 sensors: PI maximum size sensors /Up (PS47) and /Lw (PS48) [1], L size sensors /Up
(PS35) and /Lw (PS41) [2] and S size sensors /Up (PS36) and /Lw (PS42) [3].
When the PS44 and PS45 are OFF, the tray is judged "paper empty."
The size detection in the main scan is made by the paper size VR /Up (VR31) and /Lw (VR32) [4] that are inter-
locked with the paper regulation plate [5].
