ABSTRACT:
A document feed roller opening mechanism and a method for operating that opener provide efficient and reliable operation. In the document feed roller opening mechanism, a print head transport motor is used to open the document feed rollers. A carrier post is implemented to engage a document insert lever when the print head carrier is positioned over a cam on the document insert lever. Thus engaged, the document insert lever rotates to pull a left end of the document insert pressure roller. The left end of the document insert pressure roller slides towards a front of the printer and a right end pivots slightly in a right frame. A spring implemented therein compresses as the document insert pressure roller moves away from a stationary document insert feed roller. This spring provides pressure to the document insert feed roller when the rollers are together. With the document insert feed rollers open, one may easily slide a document in from the side of the printer.
