[Registration roller]
Corrects the skew of the paper feeded to the folding unit.
[Folding roller 1]
Gives the paper a first fold in conjunction with folding roller 2 at the folding operations.
[Folding roller 2]
Gives the paper a first fold in conjunction with folding roller 1 at the folding operations and gives the paper a second fold in
conjunction with folding roller 3.
[Folding roller 3]
Gives the paper a second fold in conjunction with folding roller 2 at the folding operations.
[Leading edge stopper]
Feeds the paper to the folding roller 2 and folding roller 3 for a second fold as the folding side of the paper bumps against
this stopper at the folding operations.
[Trailing edge stopper]
Feeds the paper to the folding roller 1 and folding roller 2 for a first fold as the paper bumps against the stopper at the C-fold
and four-fold and two-fold operations.
[Leading edge pushing guide]
The guide retains the first of the folds during a C-fold operation, forces a second fold into the paper during a four-fold operation
and is moved beforehand to serve as a branch during a two-fold operation.
[Release timing sensor (S31)]
Stops the feeding of paper when the specified time has lapsed from detecting the paper for the registration correction.
[Upper stopper paper sensor (S33)]
Detects the presence of paper before the leading edge stopper.
