Document feeder method
View Patent ↗A document feeder method is disclosed. The document feeder method includes providing at least one cantilevered roller shaft in the printer for advancing the document, and coupling a supported end of the at least one cantilevered roller shaft to a frame of the printer such that an unsupported end of the at least one cantilevered roller shaft floats. This decreases the cost of production by eliminating the need for additional frame hardware and/or more rigid frame hardware. The document feeder method can be implemented in existing designs.
1. A method for feeding a document through a printer, the method comprising:
providing at least one cantilevered roller shaft in the printer for advancing the document, wherein the at least one cantilevered roller shaft comprises a distal end and a proximal end;
coupling only the proximal end to a frame of the printer such that the distal end floats;
coupling a bearing to the at least one cantilevered roller shaft, wherein the bearing is a cylinder having a same axis as the at least one cantilevered roller shaft, wherein a portion of the cylinder is raised away from the axis, wherein the raised portion comprises a surface that contacts a drive roller shaft; and
coupling a spring to the frame and to the bearing such that the at least one cantilevered roller shaft is spring loaded against the drive roller shaft.
2. The method of claim 1 further comprising
providing at least one roller coupled to the at least one cantilevered roller shaft;
providing at least one second roller coupled to the second roller shaft, wherein the second roller shaft comprises a second distal end and a second proximal end;
coupling the second proximal end to the frame of the printer such that the second roller shaft is cantilevered and the second distal end floats;
inserting the document in a document path of the printer until the document reaches the at least one roller and the at least one second roller; and
rotating the at least one roller and the at least one second roller to advance the document along the paper path.
