squeezing plates operate based on the dimensions.
If the bottom size of the tray is like the example (No.2), you must squeeze
more than for the size "b". Otherwise the film may not be sufficiently
attached to the bottom. In such a case, use L/R FOLDERS.

- The default wrapping conditions are calculated based on the tray width, depth, and height.

- Specify a relative value from the default for each item. Specifying a +5 value for an item configures the

operation as +5 timing or amount to its default value.

- Common items are linked between [TRAY(BASIC)], [TRAY(ADJUST1)], and [TRAY(ADJUST2)] screens.

(A change of a value in one screen is reflected to the other screens)

- You can enter a value in a range from -99 to +99. Even if you enter a value over the limit for the item, the

● Points of caution in mounting the clamp plate.
・Mount the clamp plate apart as much as possible from the round belts on the side of catching film.

Maintain space between the clamp plate and the round belts as much as possible. If space is insufficient,
the round belts may run off the clamp plate and get stuck on the plate, making it impossible for the belts
to return to their original positions

3） Insert the paper when the clamp is open. (The photograph shows the center clamp.)

Check the following two items.

•When the paper is caught, pull it and check
whether the solenoid is located at a position
where maximum resistance is given.
For procedure to adjust the solenoid, see the
next page.

•Check that resistance is uniformly given over the
whole clamp width. When a thin piece of pape
is used, slide it left and right for checking.

2） Select [FRONT CLAMP,] [REAR CLAMP,] o

[ALL CLAMPS,] as required, before execution.
The clamp starts the open-close operation.

8） Remove the hexagonal nuts (2) placed under the shaft and set the lift head.
9） Check that the gap between the bottom of the shaft and the frame is 1 – 3 mm seen from under the

10） If the gap is not 1 – 3 mm, repeat the above procedure 5 through 9 to adjust height.

If the gap still does not fall in the range of 1 – 3 mm, loosen the hexagonal bolts (3) in the back to
adjust height in a similar way.

NOTE:
The check on the lift can be conducted by executing [Unit Operation] l [Lift] in the Maintenance

Adjustment Mode.
In this case, check that the top end of the lift hits on the shaft. If you hear a sound when the lift goes up,
the situation is OK.

from moving to the top of the hole.

At the same time, set one facet of the inside nut
vertical as shown in the photograph. Under the
condition that one facet of the nut is not vertical,
the film holder may hit the nut.

Set one facet in the
vertical direction.

2） Similarly, set the roller position on the other side

NOTE:
If the release solenoid is not adjusted properly, the following trouble may occur:

•Film cutting operation is abnormal when film-over error is released.

•Film cutting operation is abnormal after film is conveyed.

2) Check that solenoid’s position is properly adjusted.

•Adjustment is OK if a gap is created between the film holder and the film arm while the film arm is being
pushed (conveying position).
