The pair of pins are spaced from each other a distance substantially equal to a distance between two legs of a staple. The pin receptor is positioned opposite the pair of pins relative to a sheet path through the staple hole forming apparatus. The pin receptor is positioned to mate with at least one of the pair of pins. One of the pair of pins and the pin receptor is configured to move towards and mate with the other of the pair of pins and the pin receptor causing the pair of pins to penetrate a sheet extending between the pair of pins and the pin receptor to form two holes in the sheet. Each of the two holes is configured to receive one of the two legs of the staple. ## Claims ### Claim 1 A staple hole forming apparatus configured to facilitate binding a plurality of sheets with a staple having two legs, the staple hole forming apparatus comprising: a fold blade; a pair of pins extending from the fold blade and spaced from each other by a distance substantially equal to a distance between the two legs of the staple; and a pin receptor positioned opposite the pair of pins relative to a sheet path through the staple hole forming apparatus, the pin receptor being positioned to mate with at least one of the pair of pins; wherein one of the pair of pins and the pin receptor is configured to move towards and mate with the other of the pair of pins and the pin receptor causing the pair of pins to penetrate a sheet extending between the pair of pins and the pin receptor to form two holes in the sheet, and further wherein each of the two holes is configured to receive one of the two legs of the staple. ### Claim 2 (depends on 1) The staple hole forming apparatus of claim 1, further comprising a carriage assembly defining the pin receptor and configured to move toward the fold blade. ### Claim 3 (depends on 2) The staple hole forming apparatus of claim 2, wherein movement of the carriage assembly is configured to clamp the sheet between the carriage assembly and the fold blade and to form the two holes in each respective sheet during a single operation. ### Claim 4 (depends on 1) The staple hole forming apparatus of claim 1, further including a pair of rollers configured to press each respective sheet around the fold blade. ### Claim 5 A staple hole forming apparatus configured to facilitate binding a plurality of sheets with a staple having two legs, the staple hole forming apparatus comprising: a pair of pins spaced from each other a distance substantially equal to a distance between the two legs of the staple; and a fold blade defining a pin receptor positioned opposite the pair of pins relative to a sheet path through the staple hole forming apparatus, the pin receptor being positioned to mate with at least one of the pair of pins, wherein one of the pair of pins and the pin receptor is configured to move towards and mate with the other of the pair of pins and the pin receptor causing the pair of pins to penetrate a sheet extending between the pair of pins and the pin receptor to form two holes in the sheet, and further wherein each of the two holes is configured to receive one of the two legs of the staple. ### Claim 6 (depends on 5) The staple hole forming apparatus of claim 5, further comprising a carriage assembly including the pair of pins, wherein the carriage assembly is configured to move toward the fold blade causing the pair of pins to mate with the pin receptor. ### Claim 7 A document binding system for binding a plurality of sheets with a staple having two legs, the document binding system comprising: a first finishing station including: a pair of pins spaced from each other a distance substantially equal to a distance between the two legs of the staple, and at least one pin receptor positioned opposite the pair of pins relative to a sheet path through the first finishing station, the at least one pin receptor being positioned to mate with at least one of the pair of pins, wherein one of the pair of pins and the at least one pin receptor are configured to move towards and mate with the other of the pair of pins and the at least one pin receptor to cause the pair of pins to penetrate at least one sheet extending between the pair of pins and the at least one pin receptor to form two holes in the at least one sheet; and a second finishing station positioned downstream from the first finishing station and including a saddle configured to accumulate each of the plurality of sheets from the first finishing station and to position the plurality of sheets on the saddle to align the two staple holes in one of the plurality of sheets with the two staple holes in the others of the plurality of sheets, wherein the second finishing station is configured to insert the two legs of the staple through the two holes formed in the plurality of sheets to bind the plurality of sheets together. ### Claim 8 (depends on 7) The document binding system of claim 7, wherein the second finishing station is configured to place a first leg of the staple through a first staple hole of each of the plurality of sheets, to place a second leg of the staple through a second staple hole in each of the plurality of sheets, and to bend the first and second legs of the staple to bind the plurality of sheets together. ### Claim 9 A document binding system for binding a plurality of sheets with a staple having two legs, the document binding system, comprising: a first finishing station including: a fold blade; a pair of pins extending from the fold blade and spaced from each other by a distance substantially equal to a distance between the two legs of the staple; and at least one pin receptor positioned opposite the pair of pins relative to a sheet path through the first finishing station, the at least one pin receptor being positioned to mate with at least one of the pair of pins, wherein one of the pair of pins and the at least one pin receptor are configured to move towards and mate with the other of the pair of pins and the at least one pin receptor to cause the pair of pins to penetrate at least one sheet extending between the pair of pins and the at least one pin receptor to form two holes in the at least one sheet; and a second finishing station positioned downstream from the first finishing station and being configured to accumulate the plurality of sheets, the second finishing station configured to insert the two legs of the staple through the two holes formed in the plurality of sheets to bind the plurality of sheets together. ### Claim 10 (depends on 9) The document binding system of claim 9, wherein the first finishing system comprises a carriage assembly defining the at least one pin receptor and being configured to move toward the fold blade. ### Claim 11 A document binding system for binding a plurality of sheets with a staple having two legs, the document binding system comprising: a first finishing station including: a pair of pins spaced from each other a distance substantially equal to a distance between the two legs of the staple, and a fold blade defining at least one pin receptor positioned opposite the pair of pins relative to a sheet path through the first finishing station, the at least one pin receptor being positioned to mate with at least one of the pair of pins, wherein one of the pair of pins and the at least one pin receptor are configured to move towards and mate with the other of the pair of pins and the at least one pin receptor to cause the pair of pins to penetrate at least one sheet extending between the pair of pins and the at least one pin receptor to form two holes in the at least one sheet; and a second finishing station positioned downstream from the first finishing station and being configured to accumulate the plurality of sheets, the second finishing station configured to insert the two legs of the staple through the two holes formed in the plurality of sheets to bind the plurality of sheets together. ### Claim 12 (depends on 11) The document binding system of claim 11, wherein the first finishing station comprises a carriage assembly including the pair of pins, wherein the carriage assembly is configured to move toward the fold blade causing the pair of pins to mate with the at least one pin receptor.
