2.3.3.2.9 Feed Roller Eccentricity Detection Function

Media are fed by the feed roller at regular intervals.
Irregular feeding of media due to the feed roller eccentricity problem, irregular printing can occur in the media feeding direction periodically.
To prevent this, the feed error encoder and feed roller HP sensor detect the presence and amount of feed roller eccentricity every rotation of the feed roller.
This function is called the feed roller eccentricity detection function. If eccentricity is detected, the media feed mount is compensated for according to the amount
of eccentricity.
