Abstract

Abstract In a method for setting paper on a printer wherein a paper guide having an extending portion extending parallel to a platen is provided opposite to the platen on a printing head reciprocating in parallel with the platen, the paper guide having an opening for exposing an ink ribbon at a position opposite a nose portion of the printing head to provide for printing on a paper inserted between the printing head and the platen, the method including the steps of placing the printing head at a position where the extending portion of the paper guide faces the paper and the opening in the paper guide is displaced away from the paper, feeding the paper between the extending portion and the platen to a position where an upper side of the paper passes beyond the opening, shifting the printing head to substantially a central portion of the cut paper, and thereafter feeding the paper to a printing start position.

Claim 1
Independent Claim 274 words
A method for setting paper on a printer having a cylindrical platen rotatable to feed paper, a printing head disposed opposite said platen and reciprocated along said platen in a direction transverse to a paper feeding direction, a paper guide carried on a front portion of said printing head so as to oppose said platen, said printing head having a nose portion, said paper guide having an opening positioned opposite said nose portion, an ink ribbon exposed in said opening, said paper guide having guide portions extending laterally from both sides of said opening, comprising the steps of: moving said printing head to a first position adjacent to an end of said platen; feeding said paper substantially tangentially of said platen while said printing head remains in said first position, said paper having a lateral edge engaged by one of said guide portions of said guide while said lateral edge is spaced laterally away from said opening and between said opening and the other end of said platen to thereby prevent contact of said paper with said opening; continuing the last said feeding step with said printing head remaining in said first position until an uppermost edge of said paper has been fed to and past the level of said opening; shifting said printing head to a second position located at a central portion of said platen so that the entire paper guide engages said paper; and feeding said paper substantially tangentially of said platen between said paper guide and platen to a printing start position to form a desired top margin on said paper while maintaining said printing head in said second position.
