There are two types of paper t ray un it: one tray and three tray types. Each
paper tray [A] is a drawer type and their function and mechanism are exactly
the same as those of the main frame .
All the electrical components of the pape r tray are controlled by the copier
main control board through the tray control board.
All the tray rollers are driven by the m ain fram e via the tr ay un it dr ive and
driven gears [B,C]. When the tray unit drive clutch [D] is energ i zed, the drive
is transmitted to the paper tray unit and the relay rollers start rotating. When
the paper feed clutch [E] for the selected paper tray is energized, paper is fed
from the paper tray to the ma in frame through the relay rollers.
