7.8.5 Stack Wheel Home

To teach the home position for the Stack Wheels,
1. Press the Stack Wheel button.
2. Press and hold the "-" button until you hear the Stack Wheel make a clicking noise. This is the
home position.
The A/D value should reading greater than zero.
3. Press the "enter" button.
4. The display will now ask for the maximum travel distance. The default value is 10.5. There should
not be any reason to change this value. Simply press "Enter" to accept this value.

7.8.6 Fold Position Center

This value is used to better balance Fold Table positions. Slight folding errors occur depending on the
weight of the paper being folded and where the Fold Tables are set. The heavier the paper weight, the
shorter the fold length typically is, and conversely for lighter paper. The greater the position set on the
Fold Tables, the greater the error will be for the actual location of the fold in the paper. This is due to
rippling (compression) of the paper when the paper impacts the stop inside of the Fold Table. The Fold
Position Center helps to offset these fold errors.
To set the Fold Position Center value, perform the following steps.
1. Turn on the folder power and allow the folder to home both fold tables normally. Do not enter
diagnostics.
2. Press the Fold Select button and specify Half fold.
3. Press the Size Select button and set the folder for 8 ½ X 11 (or A4).
4. With the Feed Table loaded with a few sheets of 8 ½ X 11 (or A4) 20# paper, press the "TEST"
button to fold two sheets.
Pay special attention to how the folded paper exits the folder. The folded edge of the paper will be
to the right and the open edges of the paper will be on the left. If the top panel of the folded page is
longer than the bottom panel, then Fold Position Center value will have to be increased.
5. Using a pair of digital calipers, measure the distance that the top panel overhangs the bottom panel.
If there is no overhang, then do not change the Fold Position Center value.
6. If there is an overhang, enter diagnostics by pressing and holding the "STOP" button for several
seconds.
7. Press button "7" to enter Offset Limits Mode
8. Press the "Paper Length" button. This will display the current center position.
