Retrieve the first folded sheet of paper from the top of the multi-folder. The first sheet is on the bottom of the stack.
If a fold is skewed, spread the paper out in the direction of paper feed shown in the diagrams above.
Carefully measure the distances between the folds (between L1, L2, L3).
Compare the Front and Rear measurements.
Refer to the table below to determine where the paper is skewing and what type of adjustment is required.

Table Key
You must refer to the "Skew Correction Reference Diagrams". The following abbreviations are used in the table above.
Term | What It Means |
|---|---|
F Long | Front measurement of L1, L2, or L3 is longer than Rear. |
F Short | Front measurement of L1, L2, or L3 is shorter than Rear. |
S1, S2, S3 | Refers to Stopper 1, Stopper 2, Stopper 3. In the diagrams these are annotated as: For a problem with the L1 fold, we adjust stopper 1. For a problem with the L2 fold, we adjust stopper 2. For a problem with the L3 fold, we adjust stopper 3. |
Raise F | Raise the front end of the stopper fence. For more, see below. |
Lower F | Lower the front end of the stopper fence. For more, see below. |
Example: FM1 (Z-fold)
First, compare the L2 measurements.
In this example, imagine that L2 is longer at the front than at the rear.
Look at the table, in the row for FM1, and the column for L2.
‘F Long’ means Front measurement longer than Rear
‘F Short’ means Rear measurement longer than Front
L2 is longer at the front, so we have an ‘F Long’ situation.
Then, on the same row of the table, look at the S2 column. It says ‘Lower F’.
This means you must lower the front end of stopper 2.
Then, compare the L3 measurements.
In this example, imagine that L3 is longer at the front than at the rear.
Look at the table, in the row for FM1, and the column for L3.
‘F Long’ means Front measurement longer than Rear
‘F Short’ means Rear measurement longer than Front
L3 is longer at the front, so we have an ‘F Long’ situation again.
Then, on the same row of the table, look at the S3 column. It says ‘Raise F’.
This means you must raise the front end of stopper 3.
