11.2 Fold Table

1. Remove the Fold Table from the folder.
2. Locate the gear on the bottom surface of the Fold Table
3. By hand, rotate the gear to both extremes of travel. Notice the position of the Paper Stop within
the Fold Table by viewing at the top surface of the Fold Table.
4. Does the Paper Stop freely move to its maximum position?
a. Yes.
b. No – This can be caused from a serious paper jam which has caused paper to become
trapped within the Fold Table, not allowing the Paper Stop to move freely. Disassembly
of the Fold Table would be required to remedy this problem.
5. Does the Paper Stop move freely to the minimum position?
a. Yes.
b. No - This can be caused from a serious paper jam which has caused paper to become
trapped within the Fold Table, not allowing the Paper Stop to move freely. Disassembly
of the Fold Table would be required to remedy this problem.
6. With the Paper Stop in the minimum position, do the 2 plastic Diverter Actuators protrude?
a. Yes.
b. No - This can be caused from a serious paper jam which has caused paper to become
trapped within the Fold Table, not allowing the Paper Stop to move freely. Disassembly
of the Fold Table would be required to remedy this problem.
7. When moving the Paper Stops off of the Diverter Actuators, do the Actuators retract on their
own?
a. Yes.
b. No – There is a small return spring located under the Top Cover of the Fold Table which
has come loose. Disassembly of the Fold Table is required.
8. Inspect the paper opening of the Fold Table to insure that is a gap large enough for paper to
enter. At the Fold Table opening, is the upper and lower plates parallel with each other?
a. Yes.
b. No – The opening is narrow in the middle. If the upper and lower plate openings are not
parallel, there is a possibility that wrinkling of the paper can occur.

11.3 Feed Wheel Inspection

There should not be any tearing evident in the Feed Wheel material. The Feed Wheel should be clean
and free of any slices or pitting. The Blue material should be secure to the aluminum hub. If there is
any damage evident in the blue portion of the Feed Wheel or the blue material is not adhered to the
hub, replacement of the Feed Wheel is required. If the Feed Wheel is dirty, clean with either Martin
Yale Roller Cleaner or rubbing alcohol and allow to fully dry before use.

11.4 Retarder

To properly inspect the condition of the Retarder, removal of the Feed Wheel is required. The Retarder
should not be pitted, torn or have any cuts. The Retarder should be free of any ink, dirt or grease.
Clean if necessary. However, with the Feed Wheel installed, cleaning of the Feed Wheel is sufficient
enough as the Feed Wheel is typically always in contact with the Retarder, allowing solvents applied to
the Feed Wheel to be transferred to the Retarder.
