ABSTRACT:
An auxiliary printing media roll holder use with printer/plotters to accomodate a large feed roll of printing media and increase the printing/plotting capacity and operational efficiency of the printer/plotter and reduce downtime due to reloading printing media rolls. The auxiliary roll holder has an elongate longitudinal frame with opposed ends adapted to be mounted between the laterally spaced legs that support the printer/plotter, longitudinal rollers rotatably mounted on the frame in parallel spaced relation, a longitudinal spindle bar removably received and rotatably engaged at opposed ends on the frame, and a pair of hubs slidably received and releasably secured on the spindle bar near its opposed ends, each having a generally cylindrical core receiving portion disposed in opposed facing relation for engaging and supporting opposed ends of a tubular core of a large roll of printing media which is drawn from the roll, passes over the roller, and into the printer/plotter. A weight bar engages the printing media and applies and maintains tension on the printing media to keep it taut and prevent it from unrolling when feeding stops and as resistance of the rolled printing media becomes lighter as it reaches the end of the roll. The auxiliary printing media roll holder also receives and supports a paper catcher that receives the printing media as it exits the printer/plotter. In a preferred embodiment the auxiliary roll holder will acomodate a 500 linear foot roll of printing media.
