8.11 Error 111 – Feed Error
This error occurs when the lower sheets of paper in the Feed Table are not being held back by the
Retarder, and the Paper Being Fed sensor, which is behind the Feed Wheel, becomes covered when
the folder is running. In short, the Retarder is not tight enough and it is not holding the lower sheets of
the paper back. Recheck the Retarder setting. There should be slight contact between the Retarder
and the Feed Wheel. If the Retarder requires adjustment, use the supplied 9/64" Hex key to adjust the
Retarder.
a. With the Feed Table down (in the load position), and the Top Cover open, turn the Feed
Wheel by hand and feel for drag on the Feed Wheel.
b. While rotating the Feed Wheel, depress the Retarder Release. There should be a
noticeable difference in drag on the Feed Wheel. If not, release the Retarder Release and
tighten the Retarder (counter-clockwise = up = tighten).
c. Without pressing the Retarder Release, if the Feed Wheel has a large amount of drag
against the Retarder, loosen the Retarder (clockwise = down = loosen).
d. Once the Retarder is adjusted, when feeding paper, pay attention to the top sheet in the
Feed Table. With a properly adjusted Retarder, the top sheet will be partially into the folder,
approximately ½ to ¾ inches more than the remaining sheets. Increasing Retarder pressure
will reduce this distance, and reducing Retarder pressure will increase this distance.
You WILL experience this error while feeding coated or glossy paper if the folder was originally
adjusted for non-glossy, plain paper such as bond, offset, index, etc.

9 Trouble Shooting

Folder will not start when the "Run" button is pressed.

9.1
1. If the display reads "No paper in Feed Table", but there is paper in the Feed Table, replacement of
the Feed Table Paper Present sensor may be required. Verify proper function of sensor through
Diagnostics (Section 7.3, Option 2 – Input Sensor Mode).
2. If the display reads "Feed Table In Load Position", replacement or adjustment of the Feed Table
Switch may be required.
9.2

The LCD Display is blank

1. Insure that the folder is plugged into a functional receptacle.

Controller PCB are functioning correctly, the display will become visible within a few
seconds.
4. Insure that the main fuse (located next to the power inlet) is not blown.
