SYMPTOM
Jam occurs with LEF A4 adhesive label paper fed through the straight paper path of High
Capacity Stacker SK5030.
CAUSE
Smooth surface of label paper tends to stick to the curved guide plate at the exit.
[A]: Straight paper path
[B]: Exit
[C]: Entrance
The problem does not occur at the entrance, because the junction gate prevents the paper
from adhering to the guide plate.
SOLUTION
Switch to SEF. This will reduce the surface contact area between the sheet and exit guide
plate. Also, the sheet becomes longer in the feed direction, enabling transport by two
rollers in the guide plate, instead of one.

OCCURRENCE CONDITIONS
The risk of the problem is higher when the following conditions are met:
Slippery paper
Solid images
SOLUTION
Place the paper holder on the paper stack before moving the cart.

SYMPTOM
Poor stacking with the High Capacity Stacker SK5030 when using the following paper
type.
- Thickness 4 (163.0g/m2) or less plain paper (uncoated)
Feed direction⇒
CAUSE
Paper with the characteristics above enable the vibration caused by the paddle rotation to
travel to the stacked sheets. As a result, the leading edge stopper cannot be moved to the
correct position. (See APPENDIX below for more details).
Potentially affected units
All models of the High Capacity Stacker SK5030.

Step 1.
Check the version of firmware installed in the High Capacity Stacker SK5030.
If v01.070:06 or later is already installed, go to step 2.
If not, install the latest version and go to step 2
Step 2.
Install the feeler extension part (FILM:SURFACE OF PAPER SENSOR ; P/N D7767004).
The paper height is lowered 3mm from the normal position, and
the vibration of the paddle against the stacked papers will be
reduced.
How to attach the feeler extension part
1) Remove the end fence assembly from the stacker.
(Refer to Shift Tray Exit Sensor, Paper Height Sensor in
Replacement and adjustment on the service manual of Stacker)

2) Wipe the area where the feeler extension will be attached with a cloth and a small
amount of alcohol.
3）Attach the feeler extension part to the feeler as shown below.
Area to wipe
Feeler：paper detection（D4472821）

Press the edge against the base of the feeler.
Put the two end faces together.

4) Reinstall the parts in the reverse order.
Step 3.
Install the cushion parts (D7767003, D4473413).
The pushing force of the paddle is reduced by lowering the paper height. As a result, the
alignment accuracy of the stacked paper will get worse. To prevent this, add the cushion
parts to the stopper to improve the pushing force.
Important:
The sponge parts (D7767003) will deteriorate
over time. Check them whenever visiting the
site and replace if necessary.
Adjust the SP settings to improve the
alignment accuracy as necessary.

APPENDIX
Poor stacking occurrence mechanism
1. Normally, paper is pushed against the end fence by both
the paddle and the leading edge stopper.
2. Depending on the conditions and characteristics of the
paper, the top of the paper can push some of the lower
sheets toward the stopper. The vibration from the paddle
rotation is transmitted to the stack.
3. At this time, the stopper cannot push the papercorrectly,
because some of the shifted sheets are interfering with
the stopper. The stop position is then shifted from the
normal position, which worsens the stacking quality.

SYMPTOM
White-colored rust forms on the handle for the tray cart.
CAUSE
Some of the liquid coating (plating solution) applied to the handle remained inside the
structure, and later leaked out of the hole(s). As a result, the coating could not dry
properly, and reacted with the handle’s metallic exterior.
SOLUTION
If the rust appears on the handle at installation, replace with the following part:
