ABSTRACT:
A paper setting mechanism of a printer for setting a sheet of paper in position around a platen roller for printing desired information includes a paper bail assembly having at least one bail roller, which is pivotally supported and normally biased so as to cause the bail roller to be pressed against the platen roller. The paper bail assembly may be set in a set position in which the bail roller is pressed against the platen roller and it may also be set in a retracted position in which the bail roller is separated away from the platen roller. After insertion of paper, the platen roller is driven to rotate first in the normal direction over a first predetermined amount and then in the reversed direction over a second predetermined amount, which is smaller than the first predetermined amount, whereby the reversed rotation of the platen roller is utilized to cause the paper bail assembly to return to its set position automatically.
