TENSION MODULE FOR WIDE FORMAT INKJET PRINTERS

摘要

Systems and methods for printing are described. One example is a tension module for a printer including a throughput roller including a length to diameter ratio of at least 10:1 and a material on the surface thereof having a friction coefficient value less than 1. In addition, the module includes a plurality of pinch rollers arranged parallel to the throughput roller and, the pinch rollers supporting the throughput roller and providing a pressure on a print medium when passed along the throughput roller. Further, the module includes a motor to rotate the throughput roller. Still further, the module includes a tension lever including a plurality of stops, each of the stops being associated with one of a plurality of tension settings. Manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the pinch rollers on the print medium.

1. A tension module for a printer, comprising:
a throughput roller adapted for a wide format inkjet printer, said throughput roller having a length to diameter ratio of at least 10:1 and comprising a material on the surface thereof having a friction coefficient value with a print medium less than 1; a plurality of pinch rollers arranged in a line parallel to the throughput roller, said plurality of pinch rollers to support the throughput roller and provide a pressure on a print medium when passed along the throughput roller; a motor operable to rotate the throughput roller, wherein the plurality of pinch rollers and the rotation of the throughput roller in combination are operable to draw the print medium between the plurality of pinch rollers and the throughput roller; and a tension lever including a plurality of stops, wherein each of the stops is associated with one of a plurality of tension settings, and wherein manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the plurality of pinch rollers on the print medium.
