The maximum paper thickness is 104.7 g/m²/28 lb. However, this thickness may differ
slightly according to various conditions such as environmental conditions (tempera-
ture, humidity), paper size, and paper fiber direction.
● When the paper is cross folded, Σ folding (folding slippage in the horizontal) and fold-
ing misalignment along sides of paper may occur due to conditions such as environ-
mental conditions (temperature, humidity), paper size and paper fiber direction. This is
not a malfunction of the machine.
