6.5.25 TEARS OCCUR AT THE LEADING EDGES OF PAPER
Paper may tear at the leading edges of paper if paper with residual burrs from cuttings is used.
This can also cause double feeds or edges of the sheets to stick together.
Cause
Burrs caught on the edges of paper when stacks are cut during manufacturing can cause the
trailing edges of the paper stick to the leading edges of the following sheets and lead to
double-feeds or continuous feeds with the trailing and leading edges sticking together.
During paper separation, if there are burrs on the leading edges, the contact between the
separation roller and leading edges can cause tearing at the leading edges. (See diagram
below.)
Condition with cutting burrs over 0.1 mm high
[A] Separation roller
[B] Feed roller
[C] Pre-separation plate
[D] Paper
Solution
Do the following for the paper being used.
1. Change the position of the paper stack.
A. Swap the front and back of the stack (leading edge and the trailing edge in the direction
of feed).
B. Turn the stack over (without changing the direction of feed).
C. If Step A, B does not solve the problem turn the stack over and change the direction of
feed.
2. Confirm that there is no moisture in the stack.
Request the operator to use paper that has been stored at acceptable range of
temperature and humidity. You can also set the machine in curl reduction mode.
