Mark the top face of the folded stack on the top exit tray. Then unfold the paper to measure the length of L1, L2, and L3. If there is an error, correct the skew at the 1st, the 2nd, and the 3rd stopper.

- When the fold operation finishes, it is difficult to determine which stopper needs adjustment even if you measure the skew at the end of a fold (excluding the half-fold case). So check the direction of skew by measuring the length of each fold while the paper is spread out.
- Except in the case of half-fold mode, you need to determine which stopper needs adjustment from the length of the 1st fold that affects the following folds.
