An improved paper feed roller assembly for the paper feed mechanism of a printer is provided with an adjustable arrangement so that a plurality of different widths of perforated edge paper may be accommodated thereby. The arrangement includes a rotatable member having a plurality of indentations which cooperate with stops to select an axial position for the feed pins mounted on the roller, corresponding to the selected indentation.

Paper feed roller assembly

A paper supply roll holder having an axle insertable through the core of a paper supply roll for rotatably supporting the paper supply roll upon a supporting bracket. The rearward portion of the supporting bracket rests upon a suitable support surface while the forward ends of a pair of resilient arms are inserted into openings upon a printer housing for releasable locking therebetween and to positively locate the paper supply holder relative to the printer. The paper extends from the supply roll over a resiliently-mounted dancer bar and into the printer where it is guided therethrough by web feeding means of the incremental-feed type. The spring elements resiliently supporting the dancer bar are adapted to yield upon incremental advancement of the web feeding means, to thereafter rotate the supply roll through a small angle as the web feeding means pauses during the printing of a line to assure that the web is fed in an orderly fashion. The paper roll supporting axle is provided with slideable caps for positively locating the paper roll and being adjustable to accommodate paper rolls of varying lengths.
