BY-PASS FEED TABLE

11.9.1 Table Open/Closed Detection
[A]
The by-pass feed table switch [A] detects when the by-pass feed table is
opened. Then the CPU turns on the by-pass feed indicator on the operation
panel.

11.9.2 Feed Mechanism/Paper End Detection

[A]
[B]
[C]
[D]
The by-pass feed table uses an FRR feed system, using the same rollers as
the LCT, and one of the solenoids (solenoid [A]; also see LCT - Paper Feed
Mechanism). Only one of the two solenoids in the mechanism is used,
because the pick-up roller does not have to drop so far as it does when
feeding from the LCT.
The user can put up to 40 sheets of paper on the by-pass feed table. Note
that the paper can be pushed right into the machine, causing jams. The user
must stop pushing the paper in when the by-pass feed indicator goes out.
When the Start key is pressed, the by-pass feed clutch [B] and the pick-up
solenoid turn on to feed the top sheet of paper.
When there is no paper on the by-pass feed table, the paper end feeler [C]
drops into the cutout in the lower guide plate and the by-pass feed paper end
sensor [D] is deactivated.
