Paper jam due to paper misfeeding or double feeding occurs
Cause:
This may occur if:
• Coated paper is set
• Paper with high smoothness is set
• Printing is done at low temperature or humidity
Solution:
1. Measure the curl of the paper.
• Type of curl
Face curl: The set paper is warped upward.
Back curl: The set paper is warped downward.
• Measurement of curl
Load one sheet of paper on a flat surface, apply the scale to the leading edge of the paper,
and measure the curl at the four edges. The maximum value is the curl value.
• Curl standard
Acceptable curl amount varies depending on the basic weight of the paper.

Back curl: 10 mm

Face curl: 10 mm
Back curl: 5 mm
