Description

This disclosure relates to a recording device and an adjustment jig. A jig used for adjusting the transport path length, and a printing apparatus in which the transport path length is adjusted by the jig, are known. The jig described in Patent Document 1 is a strip-shaped member with a measurement pattern formed on it. One end of the jig is attached to the winding shaft and locked to the media support. The other end of the jig is fed through the paper feed opening from the paper discharge opening.
