When the sheets are fed to the staple unit inside the finisher, they may be overlaid, resulting in a misalignment of 5 mm (0.2 inches) relative to each other after stapling.
When coated or other paper producing higher paper-to-paper friction is used, the paper edges are not aligned properly, resulting in misaligned stapling.
This is likely to occur if:
Coated or other paper producing higher paper-to-paper friction is used.
Thin or other limp paper is used.
