A861D103.WMF
The paper tray holds 500 sheets. The paper feed roller [A] drives the top sheet of
paper from the paper tray to the copier. The friction pad [B] allows only one sheet
to feed at a time. The friction pad applies pressure to the feed roller with a spring
[C].

The SP modes mentioned in this section apply to A250 only, and not to G038.
The paper size switch detects when the tray is pushed in.
When the pa per tray is pushed into the mach ine, the pin [A] for the lift moto r
pressure shaft engages the lift motor coupling [B] and the pin [C] for the bottom
plate lift shaft in the tray engages the bottom plate pressure lever coupling [D]. The
pin [E] on the rear of the tray pushes the lock lever so that the lift motor can lift the
bottom plate pressure lev er .
The lift motor turns on, and turns clockwise as viewed on the diagram. The main
pressure spring [K] pulls the bottom plate pressure lever, and this lifts the tray
bottom plate.
When the top of the stack touches the feed roller, the motor cannot pull up the
plate any more, so it pulls the actuator [G] into the lift sensor [F].
The pressure of the feed roller on the paper is now too high, so the lift motor
reverses to reduce this pressure. It reverses for 300 ms or 600 ms, depending on
the paper size. For smaller paper, it reverses the larger amount (600 ms) to reduce
the pressure more.
When the paper tray is pulled out, t he pins [A, C] disenga ge from the couplings [B,
D], and the bottom plate drops. To make it easier to push the tray in, the lift motor
rotates backwards 1.7 seconds to return the bottom plate pressure lever coupling
[D] to the original position.

PAPER LIFT MECHANISM 17 May, 1999
The paper size thresholds for this feature depend on SP1-908-8 and 9. (Note that
there are two paper size thresholds: small and middle. Some models only use the
small threshold.) The amount of reverse depends on SP 1-908-1, 2, and 3. (See
the table later in this section for details of how these SP modes work.)
For A4-width paper or wider, a projection [H] on the side fence engages the
secondary pressure spring [J] through a lever [I] . Then, the secondary pressure
spring [J] applies paper feed pressure in addition to the main pressure spring [K], to
ensure that extra pressure is applied to wider paper.
As stated earlier, various SP modes control this mechanism. The following table
summarizes them.
No Middle Size Programmed
(Default for A250)
Paper width:
More than 1-908-8
(Default: Wider than HLT)
Amount of reverse:
1-908-1
(Default 300 ms)
Paper width:
1-908-8 or less
(Default: HLT or narrower)
Amount of reverse:
1-908-2
(Default: 600 ms)
With Middle Size Programmed
Paper width:
More than 1-908-9
Amount of reverse:
1-908-1
Paper width:
More than 1-908-8, up to and
including 1-908-9
Amount of reverse:
1-908-3
Paper width:
1-908-8 or less
Amount of reverse:
1-908-2
When the paper tray is pulled ou t, the pins [A, C] disengage from the couplings [B,
D], and the bottom plate drops. To make it easier to push the tray in, the lift motor
rotates backwards 1.7 seconds to return the bottom plate pressure lever coupling
[D] to the original position.

[A]
[B]
[C]
A861D105.WMF
If there is some paper in the paper tray, the paper stack raises the paper end feeler
[A] and the paper end sensor [B] is deactivated.
When the paper tray runs out of paper, the paper end feeler drops into the cutout
[C] in the tray bottom plate and the paper end sensor is activated.
When the paper tray is drawn out with no paper in the tray, the shape of the paper
end feeler causes it to lift up.

[C]
A861D107.WMF
The SP modes mentioned in this section apply to A250 only, and not to G038.
The amount of paper in the tray is detected by the combination of on/off signals
from two paper height sensors [A] and [B].
When the amount of paper decreases, the bottom plate pressure lever [C] moves
the actuator up.
The following combination of sensor signals is sent to the copier.
Amount of Paper Paper Height Sensor 1 Paper Height Sensor 2
Near End OFF ON
30% ON ON
70% ON OFF
100% OFF OFF
When the tray contain s paper of a small width, the paper feed pressure may
become too low when the thickness of the stack of remaining paper has
decreased. The lift motor rotates forward 300 ms after the sensor detects a certain
amount of paper remaining in the tray to increase paper feed pressure, simulating
the pressure generated by a full tray.
The amount of remaining paper depends on SP modes 1-908-6 and 7. The amount
of forward rotation depends on SP1-908-4 and 5. Note that there are two paper
size thresholds: small and middle (this is the same as for the paper lift mechanism
described earlier). Some models only use the small threshold. The paper size
thresholds depend on SP1-908-8 and 9.

There are four paper size microswitches [A] on the front right plate of the paper tray
unit. The switches are actuated by a paper size actuator [B] behind the paper size
indicator plate, which is on the front right of the tray.
Each paper size has its own actuator, with a unique combination of notches. To
determine which size tray has been installed, the CPU reads which microswitches
the actuator has switched off.
The CPU disables paper feed from a tray if the paper size cannot be detected. If
the paper size actuator is broken, or if there is no tray installed, the Add Paper
indicator will light.
When the paper size ac tuator is at the "*" mark, the paper tr ay can be set u p to
accommodate one of a wider range of paper sizes by using user tools. If the paper
size for this position is changed without changing the user tool setting, a paper jam
will result.

Side Fences
If the tray is full of paper and it is pushed in strongly, the fences may deform or
bend. This may cause the paper to skew or the side-to-side registration to be
incorrect. To correct this, each side fence has a stopper [A] attached to it. Each
side fence can be secured with a screw [B], for customers who do not want to
change the paper size.
End Fence
As the amount of paper in the tray decreases, the bottom plate [C] lifts up
gradually. The end fence [D] is connected to the bottom plate. When the tray rises,
the end fence moves forward and pushes the back of the paper stack to keep it
squared up
