Smooth out any curls in the paper before loading translucent paper (vellum).
When using paper which was stored in high humidity and significantly wavy, cut its edge by 1 m or more before copying it.
When using translucent paper, load it in a grain direction.
When using paper which has been stored in a humidity of 30% or below, cut approximately 1,000 mm of its end just before using it or use the humidifier.
If you continuously copy in low temperature and the delivered sheets are bent at the corners, copy each sheet with an interval of approximately 3 minutes.
If you continuously copy 50 or more sheets of translucent paper of the length of A0 paper or more with a solid-filled area that has the width of 2 mm or more and length of 900 mm or more, it may cause the background to be stained. If this happens, leave the machine idle for a while to reduce the problem.
