again.
Tighten the fixing screws properly.
Correct the folding misalignment along
the sides of the paper using the skew
correction knob.

Adjust the paper feed guides to the
paper firmly, ensuring no gaps.
Align the paper well before stacking on
the paper feed tray.
Lower the processing speed.
Do not use paper outside the
specifications.
