The rear side fence [A] and front side fence [B] can be moved to change the
paper size. This is accomplished by loosening the screw and moving the rear
and front side fences to another slot.
The paper size detection sensors are mounted under the paper tray bottom
plate. When the rear side fence is inserted into one of the paper size position,
it enters one of the three photointerrupters. The signal from this sensor
informs the CPU which size paper (LT, LG [U.S.A. versions], or A4 [European
versions]) is in the tray.
