3. OVERVIEW
There are two types of paper tray unit: the two-tray and three-tray types.
Each paper tray [A] is a drawer type that can hold up to 500 sheets of paper.
The paper feed mechanism uses an FRR feed system. The function of the
system is exactly the same as for the main machine except that there is no
paper size detection. The paper size for each paper tray is input at the
operation panel, either by the user or by a technician.
All the electrical components of the paper tray are controlled by the copier
main board through the tray interface board.
