envelop (when use MK-746)

In combination with MK-746 and the specific size of the envelope, the no feed JAM (J-1501) or
the paper skew may occur.

When the both sides of leading edge of the envelope is curled upward, it contacts with the edge
of the paper feed guide plate of the tray and generates friction. Consequently, the no feed JAM
or the paper skew occurs.
