Abstract
A self-threading and feeding arrangement for a printer including a drop-in supply station, a printing station and a take-up station. A pay-out roller is journaled across the bottom arcuate wall of the supply station for supporting a web of print receiving media placed therein. A take-up spool includes a retainer for interengaging with a lead of the media web to positively draw the web around the rotated spool. The take-up station also includes a slot-like exit guide chute that has a contoured tip for cooperating with the retainer on the take-up spool, during loading of a new roll, to place the web lead into engagement with the retainer. A drive roller, and preferably the pay-out roller, are driven by a first stepping motor, and the take-up spool is driven by a separately actuable second stepping motor.
