There are two standard paper trays. Each tray holds 550 sheets.
Each tray uses a friction pad (4) to separate paper so that only one sheet feeds at a
time.
The paper feed roller (2) and shaft do not separate from the tray when the tray is pulled
out. This prevents paper from getting caught inside the machine when a tray is
removed.
The two relay sensors are used to detect paper jams. The upper relay sensor (6)
detects jams for paper fed from either tray of the main machine. The lower sensor (8)
detects jams if paper is fed up from the optional paper feed unit or LCT.
