14. USING ART PAPER AND COATED PAPER
14-1. Characteristics of Art Paper and Coated Paper
Art paper and coated paper often stick to each other due to the printing ink and become difficult to
separate, resulting in double-feed. When using these types of paper, follow the procedure below.
Stack paper on the paper feed tray after neatly aligning the paper, and set the paper
feed guides.
For precautions on paper, refer to “7. PRECAUTIONS PRIOR TO USE” (
☞
p.18).
2
Set the paper feed pressure adjusting lever to “3”.
Set the paper feed pressure within the “3” to “5” range on the scale.
If paper slips and mis-feed occurs, increase the paper feed pressure to “4” or “5”.
Paper feed pressure increases as the scale value increases.
3
Open the top cover, and set the separating pressure adjusting dial to “2.5”.
After setting, close the top cover.
If double-feed occurs, increase the paper separating pressure by 0.5 at a time.
Paper separating pressure increases as the scale value increases.
4
Press the test key to perform test folding, and check the finish.
If deformed folding occurs, the paper may not have reached the folding plate folding stopper. One solution is to lower the
processing speed.
5
Some recycled art paper and coated paper may be flimsy and inappropriate for folding.
NoteNote
14-2. Operation Procedure
Fan the paper well.
1
Art paper and coated paper need to be fanned well compared to fine quality paper such as copy paper.
NoteNote
Do not stack too many sheets of paper on the paper feed tray, the amount of which should be about half the
height of the paper feed guide (approx. 1.0"). If too many sheets are stacked, the paper will stick to each
other from its weight and become difficult to separate, resulting in double-feed.
NoteNote
Do not use fine quality paper such as copy paper with the paper feed pressure and paper separating
pressure settings for art paper and coated paper. Due to the high paper feed pressure, double-feed occurs
more easily. In addition, due to the high paper separating pressure, the paper may be damaged at the lead
edge. When using fine quality paper, always return to paper feed pressure and paper separating pressure
settings to levels suitable for fine quality paper.
NoteNote
Other steps are the same as standard folding of standard paper.
