A process motor (82) provides bidirectional motive force to a printer (50) drive train (80) that selectively engages with multiple self-homing printing functions. A print head (52) is tiltable to a maintenance position and a transfer roller (64) is loadable against a transfer drum (54) by respective missing tooth gear (96, 160) latching mechanisms. A print media pick roller (122) and transfer drum maintaining devices (70, 72) are actuated by spring-wrap clutches (114, 236) that are protected from reverse rotation by a one-way clutch (106). Print media transport rollers (140, 142) are selectively engaged with the one-way clutch by an electro-mechanical clutch (128). A picked and transported print medium (56) receives an ink image from the transfer drum and is stripped therefrom by stripper fingers (66) and directed into media exit rollers (212, 220) for delivery to a media output tray (68). The stripper fingers and exit rollers are actuated sequentially by cams (180, 182) that are slaved to the transfer roller loading function.

An apparatus and method are described for applying an intermediate transfer surface, in the form of a liquid layer, on a support surface as may be used in a phase change ink printing system. The apparatus includes an applicator assembly for distributing the liquid layer onto the support surface to produce the intermediate transfer surface and an apparatus for metering the liquid layer uniformly on the support surface. The applicator assembly has a contact medium for removing foreign matter from and delivering the liquid onto the support surface. Preferably the contact medium is a liquid impregnated web that is periodically incremented to present a clean web surface in contact with the support surface. The metering apparatus is a hydrodynamic blade that uniformly distributes the liquid intermediate transfer layer over the support surface. The apparatus provides for sequencing of the applicator, then the applicator and the blade together, and finally the blade only to ensure proper application of the intermediate transfer layer and cleaning of the support surface.

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).

A media preheater positioned in the media path of a printer and having a fixed heater and a movable plate array biased toward the heater such that printing media passing between the heater and the plate array is compressed therebetween and heated. The preheater may be positioned upstream of a print head and downstream of a media advancing mechanism in the media path. More than one plate may be provided in the plate array to accommodate non-planarity of the heater or the printing medium. The plate array may be a thermally massive element that contacts the heater when no media is present, thereby permitting the medium to be heated from both sides.

An ink stick push block for use in a system for feeding solid ink sticks in a phase change printer, wherein each solid ink stick has an ink stick face surface having an ink stick face surface contour and an ink stick rear surface having a nonplanar ink stick rear surface contour, the ink stick push block. The push block includes an ink stick push block face having a nonplanar ink stick push block face contour, wherein at least a portion of the nonplanar ink stick push block face contour is the complement of at least a portion of the nonplanar ink stick rear surface contour.

A phase change ink transfer printing apparatus (10) applies a liquid intermediate transfer surface (12) to a heated drum (14, 28). Because the intermediate transfer surface is a thin liquid layer, molten ink drops (122) striking it flatten and spread out (110, 112, 114, 130) prior to cooling and solidifying as an ink image (26, 130) at the drum temperature. After the ink image is deposited, a print medium (21, 132), such as a transparency film, is fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23). As the drum turns, the print medium is pulled through the nip to transfer the ink image to the print medium. When in the nip, heat from the drum and print medium combine to heat the ink in accordance with a process window (90), making the ink sufficiently soft and tacky to adhere to the print medium but not to the drum. The ink drops comprising the ink image have a desired diameter to height ratio of from about 1. 5:1 to greater than about 4:1 using the apparatus and method of printing disclosed.

A printer having a paper printing mode and a transparency printing mode detects a leading edge portion of an image-receiving sheet. Based on detection of an opaque leading edge portion of a transparent sheet, the paper printing mode is disabled and a sheet size having boundaries is selected. The printer deposits ink on the transparent sheet within the boundaries of the selected sheet size.

A method for controlling an imaging apparatus based on an intelligent usage tracking system is provided. The method monitors use of the imaging apparatus over a period of time and uses the collected data to predict future use. The collected data is used to control the imaging apparatus to minimize warm-up delays and to maximize time in one or more standby modes.

A method and an apparatus for processing an image transparency entails the application of an intermediate transfer surface of a layer of sacrificial liquid to a supporting surface and the deposition of a phase change ink onto the liquid layer. The inked image is then contact transferred to an optically transmissive final receiving substrate, such as a plastic transparency.
