2-6-11. Adjusting the home position of the switching shaft (stopping position) in single folding
The switching shaft switches the paper conveyance route between single folding and other folding modes.
To adjust the home position of the switching shaft, adjust the clearance between folding roller 1 and tip of the
switching shaft to 0.2 to 0.4 mm (0.008" to 0.016") when the folding stopper of folding plate 2 is stopping at the
home position.
If this adjustment is not carried out appropriately, problems may occur in folding which may cause conveyed paper
to become thick such as the single folding of thick paper and cross folding. These problems include flattening of the
lead edge of folded paper and paper jam at the folding roller.
In the single folding of thin paper, one folding wrinkle line occurs near the 15 mm (0.59") position from the folded
line.
The correction value of the switching shaft home position adjustment in the maintenance mode does not affect the
folding size.
