Preventing Multiple Feeding in Post Inserter
Multiple sheets may be fed when loaded in the upper tray/lower tray of the post inserter.
Three feed rollers are attached to each of the upper tray and lower tray, and used for feeding sheets. Locking the rollers on both sides and using only the middle one may be effective in preventing small cover sheets from skewing.
As shown below, push both roller lock levers inside to lock them.

Lower tray:
Be sure to lock the rollers on both sides, when loaded. In normal mode, return the roller lock levers to the original positions.
