B. Registration Shutter
1. Outline
This printer has a paper alignment system. A reg-
istration shutter is used to control registration.
If print paper of large width is skew-fed into a
printer with a registration roller system, the left
edge of the paper may be pinched or hit by the
registration rollers. This results in high friction
between the paper and the roller so that the end
of the print paper may not be aligned. For this
reason, a registration shutter is used in the printer
to overcome this problem by reducing friction.
