Folds Soiled by Multi-Sheet Folding
Cause:
If multi-sheet folding is performed after a large number of Z-folds have been performed, the tip of the blade used for the multi-sheet folding may be soiled, resulting in soiled paper.
This will produce paper soil of 1-3 cm (0.4-1.2 inches) in width (equal to the width of the blade) in the fold in the center of paper.
Solution:
Clean the blade.
Open the front cover of the multi-folding unit.
Pull the multi-folding unit out.
Turn the N11 dial counterclockwise until the blade appears.
The blade is located in the right part of the multi-folding unit.
Wipe the tip and top of the blade with a soft dry cloth.
Be careful not to damage the blade.
After cleaning, restore the machine so that it resumes operation.
Apply multi-sheet folding and print 3-5 copies. The paper soil will disappear.
