• The 1st tray lift motor switches on to raise the stack until the

actuator enters the pick-up roller unit position sensor again and
switches the lift motor off.

• This cycle repeats until the end of the job or until paper runs out.

When feed starts with a full tray, the actuator [A] on the rotating
shaft of the bottom plate lift arm [B] is at the 1st tray lower limit sen-
sor [C].
As paper feeds and the stack grows smaller, the lift arm rises and
the actuator descends until the actuator reaches the 1st tray upper
limit sensor [D]. At this time the operation panel signals near-end
for the 1st tray.
When the last sheet feeds, the paper feed sensor, a photosensor
(not shown) signals that paper has run out.

The side fences (1) and (2) can be adjusted to standard and non-
standard paper sizes.
When the side fences are moved to match the paper width, a feeler
[A] slides along the wiring patterns on the paper width switch termi-
nal plate [B].
The combination of the following two factors determines the paper
size:
• The position where the feeler activates the terminal
• The status of the paper length sensor [C] (ON or OFF).
The paper end sensor [D] de-activates when the last sheet is fed
and reports that the paper tray is empty.
The paper size is detected by six sensors whose combined read-
ings are used to detect the following paper sizes.

(Yes) Width and length sensors can detect paper sizes automati-
cally.
(*) Accurate paper size detection requires setting with the "Tray
Paper Setting" key on the operation panel.

Service Manual

 

The 1st transport roller [1] (driven by the 1st transport motor) pulls
the paper from the 1st tray and feeds it into the vertical paper path.
The 2nd transport roller [2] (driven by the 2nd transport motor) pulls
the paper from the 2nd tray and feeds it into the vertical path.
The vertical transport motor [3] drives the vertical transport rollers
(1) and (2) that feed the sheets into the horizontal feed path.
The horizontal transport motor [4] drives the horizontal transport
rollers (3) and (4) that feed the covers (and paper passing straight
through) out of the cover interposer tray.
