Tri-folding
1. The paper at the center-folding unit proceeds to the position at which it is center-folded as driven by CF
adjustment motors 1 and 2.
2. The sheets are aligned with each other width wise as the CF blade pushes the center of the paper
upwards and crowds the CF left and right rollers.
3. CF feedshift guide is operated by the CF feedshift solenoid which switches the paper path and conveys
the paper to the relief section.
Figure 2-1-20
4. When the paper is stuck in the parking bay, its flexure is pinched between the right-side and top center-
folding rollers so that the paper is folded inward.
