FM4 Letter Fold-in
In Fold Method 4 (FM4):
• The leading edge of the paper is stopped by Fold Stopper 1.
• The paper flexes toward the nip of fold rollers ¬ and Á which performs the first fold.
• Fold Stopper 2 stops the paper and flexes it into the nip of fold rollers Á and ®.
• Fold rollers Á and ® perform the second crease and feed the folded paper in exit path.
• Fold Stopper 3 is not used.
FM3 and FM4 follow the same sequence but the resultant fold is different:
• In FM3 Fold Stopper 1 is positioned high so a short length of paper is allowed to feed before flexing
toward the nip starts.
• In FM4 Fold Stopper 1 is positioned low so a long length of paper is allowed to feed before flexing
toward the hip starts.
• This positioning of Fold Stopper 1 accounts for the difference in folding at the next nip.
