Abstract
An inkjet pagewidth printer includes a chassis. A print media feed mechanism is mounted on the chassis to feed print media along a feed path. A pair of opposed transfer rollers are rotatably mounted on the chassis to contact the print media as it is moved along the feed path. A displacement mechanism is operatively engaged with the transfer rollers to displace the rollers into and out of engagement with the print media. A pair of opposed pagewidth printhead assemblies is mounted on the chassis to carry out a printing operation on respective transfer rollers so that print can be transferred to the print media. A cleaning station is operatively positioned with respect to the transfer rollers to clean the rollers subsequent to the print being transferred to the rollers. Control circuitry controls operation of the printer. A memory stores data related to images and text to be printed.
