Abstract: A recording device for effecting recording on a recording material by a recording head, said recording device including a recording unit including a reciprocally movable carriage for carrying the recording head, a platen for supporting a recording material at a position opposed to said carriage, and a feeding roller, disposed upstream of said platen, for feeding the recording material, a recording chassis supporting said carriage, said platen and said feeding roller, and a sheet feeding unit including a feeding path for feeding the recording material to said feeding roller from a plurality of feeding portions, and a side chassis supporting said feeding path at both lateral sides with respect to a moving direction of the recording material, whereby said recording chassis of said recording unit and said side chassis of said sheet feeding unit are fixed to each other.

Abstract: An ink jet recording apparatus incorporating a plurality of ink tanks that is independently exchangeable. An amount of ink suction for a suction recovery operation is changed and controlled based on the ink tank being exchanged. In this way, a small-sized apparatus operating at a low running cost is possible by saving and decreasing the ink amount discharged by controlling the ink discharge more than necessary during the suction recovery process after exchanging the ink tank.

Abstract: An ink jet printing method and an ink jet printing apparatus are provided which minimize an area to be printed that overruns from edge portions of the print medium, even for an irregular-shaped print medium. The printing apparatus has an overrunning ink reception opening formed in the platen as a notched portion to accommodate ink ejected beyond the edges of the print medium. When the edge portions of an irregular-shaped print medium are to be printed, a control is made to accommodate almost all volume of ink ejected beyond the edge portions is accommodated in the overrunning ink reception opening. With this arrangement the amount of ink ejected from the edge portions of even the irregular-shaped print medium can be adjusted so that the interior of the platen and printing apparatus can be prevented from being contaminated and a wasteful ink consumption minimized, thus realizing a satisfactory “marginless printing.

Abstract: A head recovery device for an ink jet recording apparatus is provided with a pigment ink discharge port for discharging pigment ink and a dye ink discharge port for discharging dye ink. The device comprises a pigment ink cap for capping the pigment ink discharging port and a dye ink cap for capping the dye ink discharge port, and, in a predetermined recovery operation, a preliminary discharge is executed from the dye ink discharge port to the pigment ink cap.

Abstract: To provide a recording apparatus for recording on a sheet by a recording head, including: a carriage for carrying the recording head and moving in a direction crossing a sheet transporting direction; a guide shaft for guiding a movement of the carriage; and a guide shaft lifting mechanism for changing a position in height of the guide shaft at three or more stages without changing a position of the guide shaft in the sheet transporting direction.

Abstract: An inkjet printer has a platen defining the position of printing medium P during image printing and an ink receiver formed in the platen to be opposite to nozzle arrays of a print head. In the inkjet printer, the print head ejects ink from the nozzle arrays for pigment ink and dye ink in accordance with print data. When borderless printing is executed on the edges of printing medium, ink is ejected to lie off printing medium and then received in the ink receiver. Then, the print head ejects dye ink to pigment ink received in the ink receiver of the platen during borderless printing using pigment ink.
