Paper feed assembly
View Patent ↗A paper feed assembly for a printer including a media tray for a stack of sheets of media to be fed, a pick mechanism capable of pivoting including one or more picking devices in contact with said media. The pick mechanism includes a media contact member which is capable of moving the pick mechanism upon contact with advancing media to eliminate contact with the media stack.
1. A method for providing second side copying to form duplex copies in an electrophotographic device, said method comprising the steps of:
providing a media feed path for feeding one or more sheets of media through said device;
providing a media tray including one or more sheets of media arranged in a stack;
providing a pick mechanism comprising an arm having opposite ends, coupled to one or more pick rollers, said arm pivoted about one end, said one or more pick rollers located at said opposite end and in contact with said media stack, said arm further including a driver for rotating said one or more pick rollers, said pick mechanism further including a media contact arm having opposite ends, wherein one of said opposite ends is configured to contact said stack or media tray and wherein said paper contact arm is coupled to said pick mechanism and extends into said media feed path;
directing the passage of sheets of paper between said pick mechanism and said stack of media,
wherein a sheet of media traveling along said feed path engages with said paper contact arm and lifts said one or more pick rollers off said stack, providing a path for said sheet to pass between said stack and said pick mechanism without contacting said one or more pick rollers.
2. The method of claim 1 including the additional step of providing a support surface for directing the passage of said sheets of media.
3. The method of claim 2 wherein said support surface includes at least one opening and wherein said one or more pick rollers extend through said opening.
4. The method of claim 1 , further including a media transport initiating mechanism capable of initiating the feeding of sheets of media along said feed path, wherein said media transport initiating mechanism comprises an autocompensator pick mechanism.
