Abstract
A finisher assembly of a multifunction peripheral includes a vertically oriented stapler and a paper transport motor. When the paper transport motor rotates in the forward direction, printed pages from the print engine of the multifunction peripheral are received via a paper chute and a feed assist roller urges the printed pages into a vertical paper accumulation cache basin. Rotation of the paper transport motor also opens a biasing plate allowing the pages to freely enter the cache basin. Once all of the pages of the print job are in the cache basin, the paper transport motor rotates in the reverse direction causing the biasing plate to bias the printed pages, in the cache basin, against a registration surface of the vertically oriented stapler unit. The pages of the print job are stapled together the stapled print job is moved to the paper tray for collection by a user.
