Abstract
A print media feeder apparatus suitable for use in an image-forming device is provided. The apparatus comprises an elevator tray holding a stack of print media connected to a housing by a transmission system. The housing comprises a hoist drum that is connected to one end of a shaft for connecting the housing to the transmission system. A spring enclosure encasing a spring is fixed on the other end of the shaft. The load of print media is transmitted to the hoist drum, from which it is further transmitted to the spring through the shaft. This results in the displacement of the spring and a corresponding vertical movement of the elevator tray to position the print media at the desired feeding level.
