Abstract:
1. An apparatus for transporting media in a printer comprising: a first bracket and a second bracket secured to a printer surface; a stationary shaft extending between the first bracket and the second bracket, a first terminal end of the shaft being inserted into the first bracket and a second terminal end of the shaft being inserted in the second bracket; a first roller rotatably mounted about the shaft; a second roller forming a nip with the first roller and a pair of elastomeric end caps, a first elastomeric end cap configured with a single opening to receive and directly contact each portion of the first terminal end of the shaft inserted into the first bracket to constrain movement of the first elastomeric end cap and the first terminal end of the shaft in a direction parallel to a media surface in the nip formed between the first roller and the second roller and to enable movement of the first elastomeric cap and the first terminal end of the shaft in a direction normal to the media surface in the nip formed between the first roller and the second roller, and a second elastomeric end cap configured with a single opening to receive and directly contact each portion of the second terminal end of the shaft inserted into the second bracket to constrain movement of the second elastomeric end cap and the second terminal end of the shaft in the direction parallel to the media surface in the nip formed between the first roller and the second roller and to enable movement of the second elastomeric cap and the second terminal end of the shaft in the direction normal to the media surface in the nip formed between the first roller and the second roller, the pair of elastomeric end caps being configured to reduce noise.
