6. The Paper Lift Spring may not be applying enough force against the Feed Wheel. This only occurs
if there are only a few sheets of paper remaining in the Feed Table (typically, less than 20 sheets).
Bending the Paper Lift Spring up a small amount usually remedies this problem.
a. With the Feed Table down in the load position, and with no paper loaded, the Paper Lift
Spring should be above the Feed Table between 1/4 and 3/8 inch. Only bend the Paper Lift
Spring if necessary.
7. The Feed Table may not be rising up as it should. This can be caused by the Feed Table Lift
Spring being out of adjustment, a lack of lubrication on the moving parts, or a mechanical problem
caused by shipping damage.
a. With no paper in the Feed Table, release the Feed Table and allow the Feed Table to rise
up on its own.
b. If the Feed Wheel compresses the Paper Lift Spring, then the Feed Table is functioning
correctly.
c. If the Feed Table is not raising, and not causing the Paper Lift Spring to make contact with
the Feed Wheel, then field service is required.
8. The Feed Clutch may not have fired.
a. Test the Feed Clutch in Diagnostics (Section 7.5 - Option 4 – Feed Mode)
b. If there is no auditable "click" coming from the Feed Clutch, and the Feed Wheel is not
rotating when the Feed Clutch is commanded to fire, then either the Main Controller PCB
has failed (no power going to the Feed Clutch) or the Feed Clutch has failed (replacement
required).
c. If the Feed Clutch is firing intermittently, replacement of the Feed Clutch is required. Do
NOT attempt to adjust the Feed Clutch. The Feed Clutch is factory adjusted for optimum
performance prior to installation onto the Folder.
9. The Paper Present sensor failure. If the Feed Table is empty and the folder continues to feed
paper, then this sensor has failed. The reason the folder is attempting to feed paper is because the
controller still thinks there is paper in Feed Table when none exists. Verify proper function of
sensor through Diagnostics (Section 7.3, Option 2 – Input Sensor Mode).
Error 102 – Exit Sensor Failure (on)
8.2
There are two possible causes for this error to occur;
1. Possible paper jam at exit conveyor and the sensor is covered.
2. If the Exit Sensor has failed and the sensor acts as if it's always sensing paper when none exists.
Verify proper function of the sensor through Diagnostics (Section 7.3, Option 2 – Input Sensor
Mode).
Error 103 – Exit Sensor Failure (off)
8.3
There are two possible causes for this error to occur;
1. A paper jam in either of the Fold Tables. Clear the paper jam from the Fold Table(s).
2. The Exit Sensor has failed and cannot sense paper in the Exit Conveyor. Verify proper function of
the sensor through Diagnostics (Section 7.3, Option 2 – Input Sensor Mode).
Error 104 – Motor Controller Failure
8.4
Caused when power is turned on and the Main Motor starts running when it should not. The Main
Motor drive circuitry has failed and the Main Controller PCB requires replacement.
