LCT PAPER TRAY SECTION
[1] Composition

Method
Wire drive
Front loading
Index sheet
*2: Remaining paper indication
The LCT can hold a large amount of paper, hence it has a
remaining paper indicator window to enable the user to
obtain a rough indication of the amount of paper remaining
in the tray.
The remaining paper detection lever moves along with the
up-down motion of the tray, and the index sheet is caused
to slide by a tension spring.

*1: Paper lift-up
The paper tray is suspended by four up-down drive wires
(wires A and B — two each).
When paper is supplied to the tray, the tray drops under the
weight of the paper, however the weight of the paper is
balanced by the tension of the auxiliary drive spring.
When the paper tray is loaded, the tray motor (M141, M142)
rotates, and the wire is wound up on the drive reel, causing
the tray to rise.
When the paper tray is withdrawn from the pedestal, the
coupling between the tray and the tray drive section is
released, hence the tray falls to a position where the weight
of the paper is balanced by the tension of the auxiliary drive
spring.
