Duplex printer with internal hard drive

Abstract

A duplex color printer includes a pair of print engines mounted in an opposed manner to define a print media feed path therebetween, each print engine including a printhead and a transfer roller for receiving ejected ink from the printhead; a pair of print media trays mounted on either side of the body for respectively containing print media; a print media feed arrangement for feeding print media from one of the trays along the print media path into the other one of the trays; an internal hard drive for locally storing pre-rasterized documents; an interface for facilitating user selection of a locally stored pre-rasterized document for printing by the pair of print engines; and a cleaning station provided in each print engine. Each cleaning station includes a resilient wiper and an absorbent sponge. The resilient wiper is provided downstream of the absorbent sponge with respect to the transfer roller.

1 . A duplex color printer comprising:
 a pair of print engines mounted within the body in an opposed manner to define a print media feed path therebetween, each print engine including a printhead and a transfer roller for receiving ejected ink from the printhead;   a pair of print media trays mounted on either side of the body for respectively containing print media;   a print media feed arrangement for feeding print media from one of the trays along the print media path into the other one of the trays;   an internal hard drive for locally storing pre-rasterized documents;   an interface for facilitating user selection of a locally stored pre-rasterized document for printing by the pair of print engines; and   a cleaning station provided in each print engine, each cleaning station comprising a resilient wiper and an absorbent sponge, the resilient wiper provided downstream of the absorbent sponge with respect to the transfer roller.   
     
     
         2 . A duplex color printer as claimed in  claim 1 , wherein the feed arrangement comprises a first motor assembly arranged upstream of the print engines to feed print media along the print media path and towards the print engines, and a second motor assembly arranged downstream of the print engines to feed print media along the print media path and from the print engines. 
     
     
         3 . A duplex color printer as claimed in  claim 1 , wherein each print media tray comprises a platen movably mounted within the housing for supporting a stack of print media, and a motorized mechanism configured to move the platen. 
     
     
         4 . A duplex color printer as claimed in  claim 1 , further comprising a body defining a plurality of docking bays for receiving ink cartridges, wherein at least one of the print engines is pivotally mounted relative to the body. 
     
     
         5 . A duplex color printer as claimed in  claim 4 , wherein the interface is defined in a vertical panel of the body, and the interface comprises:
 a display configured to display information to a user;   a keypad to enable the user to input information;   a print button so that the user can actuate the printer; and   a stop button so that the user can stop the printer.   
     
     
         6 . A duplex color printer as claimed in  claim 1 , wherein each print engine comprises:
 a pair of printheads; and   the transfer roller engages with the print media fed along the print media path to transfer the received ink onto the print media.   
     
     
         7 . A duplex color printer as claimed in  claim 6 , wherein at least one of said pair of printheads and said transfer roller can be moved into contact with each other, whereby the printheads are capped by the transfer roller. 
     
     
         8 . A duplex color printer as claimed in  claim 4 , wherein the docking bays are defined in a roof of the body.
