Abstract
A media sensing system monitors the movement of media along the media pathway (76) as a sheet of printing medium (56) is transported through the printer 50. The media sensing system permits a hand fed sheet of printing medium (56) to be detected by a sensor (302) and signal to be sent to inactivate a print media pick roller (122) that automatically feeds print media. The sensing system senses the transport of print media (56) by print media transport rollers (140, 142) detecting media sheet size, activates the transfer process of an image from the liquid intermediate transfer surface on the transfer drum (54) to a sheet of print medium (56) after pausing the sheet of print medium to synchronize its movement along the media pathway with the imaging process, and activating the preheater (60) to heat the print medium (56) prior to image transfer and fusing. The sensing system senses the exit of the print medium (56) from the media exit rollers (212, 220) for delivery to an output tray (68).
