PAPER FEED

Tray Capacities

The machine has three built-in paper trays:
• Tandem LCT (Tray 1). 1550 + 1550 sheets
• Universal Tray (Tray 2) 550 sheets
• Universal Tray (Tray 3) 550 sheets
The machine also has a by-pass feed tray which can hold 100 sheets (T-6200).

Built-in Feed Stations

• Paper feed and separation. Standard FRR system with a torque limiter for
paper separation and feed. Each tray has an independent stepper motor to drive
its paper feed mechanisms.

• Tray Lift motors. Provided for each tray, easily disengage when a tray is
removed and engage once again when the tray is re-installed. In trays 2 and 3,
the lift of the motors on the bottom plates is also used for paper near-end
detection.
• Tandem tray paper end. A sensor mounted near the top of the right rail signals
paper near end and another sensor under the bottom tray signals paper end after
the last sheet is fed. Three paper height sensors, mounted on the left rail, are
actuated as the actuator rises with the bottom plate. The combinations of
actuating and de-actuating these sensors as the plate rises are used to signal
the paper supply display on the operation panel.
• Paper size detection. For the tandem tray (Tray 1), an SP setting is required
(SP 5959 001). For the universal trays (Tray 2, 3), there is a 5-step manual
switch on each tray.
• Vertical Transport. A grip roller at each feed station feeds the paper into the
vertical paper path.
• Heaters. Two anti-condensation heaters are provided for the built-in paper feed
stations.

By-pass Feed

• Capacity: 100 sheets.
• Paper feed and separation: Standard FRR system with a torque limiter for
paper separation and feed. By-pass tray motor and clutch.
• Paper end detection: Photointerrupter and feeler.
• Size detection: Side fence is used for width detection, registration sensor pulse
count is used for length detection.
• Thick paper feed: By-pass feed clutch switches on twice.

Paper Registration

• Paper is guided to the registration roller from five sources: the 3 built-in paper
trays, 1 by-pass tray, and 1 duplex tray.
• There is a mylar strip over the entire length of the registration roller.

Jam Removal

Pulling out a paper tray releases the pressure on the rollers, making it easy to
remove paper jams.
