2.1.9.3 Prevention of paper bent from the fusing

Sometime the paper ejected from the fusing is bent in wave shape. The
reason why this happens is that the temperature around the fusing roller is
not even. In order to prevent this, the printer rotates the half circle after the
printer receives the printing order, and makes the temperature around the
fusing roller even.
