An elevator moves the tray up or down when it is in use. The HCF
trays have Paper Level switches which detect the position of the
elevator to determine the fullness of the tray. Paper Size switches
detect the size of the paper loaded in the trays.
Each processor feeder tray and HCF tray has a control panel
consisting of a button, indicators, and paper level displays, as shown
in figure 1-7.
