Abstract: A printhead assembly to eject ink onto an intermediate transfer medium to form an image and an inkjet printer with the same are provided. The printhead assembly has a plurality of printheads disposed around the intermediate transfer medium to eject ink thereto; a supporting body to connect the plural printheads together; a printhead reciprocating unit to reciprocate the supporting body in a major scanning direction; and a printhead adjusting unit to move the supporting body to adjust an interalignment in the major scanning direction of the plural printheads.

Abstract: An image forming apparatus to set up a laser scanning unit includes a laser scanning unit to irradiate light, a photosensitive member on which an electrostatic latent image is formed by receiving the light irradiated from the laser scanning unit, a supply unit to apply a developing agent to the electrostatic latent image formed on the photosensitive member to form a visible image, and a transfer unit to transfer the visible image formed on the photosensitive member to a printing medium, wherein a time period in which the photosensitive member is rotated from an exposure point of the photosensitive member at which the light is incident to a transfer point of the photosensitive member at which the visible image is transferred, is based on a variation time period of a rotational speed of the photosensitive member.

Abstract: An image drum presses and transfers an ink image formed on the surface thereof onto an image receiving medium, and an image system having the same of a solid inkjet image forming apparatus. The image drum includes a first cylindrical body which forms an image on the surface thereof and transfers the image onto an image receiving medium by pressure; a heat generator formed in the first cylindrical body which heats the first cylindrical body; a space part formed between the first cylindrical body and the heat generator; and including a certain amount of operational fluid transferring heat between the first cylindrical body and the heat generator. The operational fluid is contained between the first cylindrical body and the heat generator. Accordingly, when the image drum is heated, the surface temperature of the image drum can be precisely and uniformly controlled, power consumption decreases, and heat is efficiently transmitted.

Abstract: An inkjet printer includes a paper-feeding unit and a plurality of printheads. The paper-feeding unit feeds paper in a progression direction. The printheads have a length greater than a width of the paper and arranged in a line along the progression direction of the paper fed by the paper-feeding unit to fire ink on the paper.

Abstract: A printhead assembly to eject ink onto an intermediate transfer medium to form an image and an inkjet printer with the same are provided. The printhead assembly has a plurality of printheads disposed around the intermediate transfer medium to eject ink thereto; a supporting body to connect the plural printheads together; a printhead reciprocating unit to reciprocate the supporting body in a major scanning direction; and a printhead adjusting unit to move the supporting body to adjust an interalignment in the major scanning direction of the plural printheads.

Abstract: A wet-type image forming apparatus includes an intermediate transfer medium for receiving images which are formed in a plurality of photosensitive media and overlapped thereon to form an image and transferring the image to a print medium. The intermediate transfer medium runs along a predetermined path. A drying unit heats the intermediate transfer medium to evaporate part of carrier included in the image on the intermediate transfer medium before the image is transferred onto the print medium. A cooling unit cools the heated intermediate transfer medium after the image is transferred onto the print medium by making the intermediate transfer medium directly contact a coolant.
