The protuberance of transverse perforation
When the fanfold transverse perforation sticks up, it may cause print quality decrease, unstable
paper feed or paper jam etc. Especially when the multi-ply paper is with many pages, it will deeply
affect the stability of paper feed. Please ensure the protuberance height is less than 1 mm.
◆
Warp between toothed holes of each ply
Please use the paper which toothed holes warp between each ply (causes by the warp of multi-ply
papers superposition) is less than 0.4 mm.
