The device includes a processor for controlling operation of the printing mechanism. An array of capacitive sensors is positioned in the body and is configured so that predetermined combinations of capacitive sensors in the sensor array, when actuated, generate signals carrying data related to the characteristic of the printing cartridge. Such predetermined combinations of capacitive sensors are actuable by the actuator formation positioned on the housing of the printing cartridge when the printing cartridge is engaged with the body so that the array of capacitive sensors generates a signal carrying said data relating to the characteristic of the printing cartridge.Type: ApplicationFiled: September 11, 2003Publication date: April 1, 2004Applicant: Silverbrook Research Pty LtdInventor: Kia Silverbrook

Publication number: 20040061736Abstract: A maintenance apparatus of an inkjet printer includes a control unit to control a drive motor for a wiping member convey unit to be in contact with a stopper two or more times in order to prevent a wiping member and a wiper disposed therein from being erroneously positioned due to an abnormal repulsive force occurring in the wiping member convey unit when the wiping member convey unit comes in contact with the stopper, due to outer impact and changes in load of the motor. The wiper-positioning method includes a first contact operation of driving the motor for the wiping member convey device to come in contact with the stopper, and a re-contact operation of controlling the motor for the wiping member convey unit to be in contact with the stopper one or more times again.Type: ApplicationFiled: June 9, 2003Publication date: April 1, 2004Applicant: Samsung Electronics Co., Ltd.Inventors: Seuk-Jin Yun, Gui-Taek Lim

Publication number: 20040061738Abstract: A recording head cartridge is mounted on a carriage scanning in a forward direction and in a backward direction along the width direction of a recording medium. The fan of an ink mist collecting section produces an airflow and collects ink mist generated when ink is discharged. When the carriage scans in the forward direction, an image is formed and the fan is not operated and when the carriage scans in the backward direction, the image is not formed and the fan is operated to collect the ink mist.Type: ApplicationFiled: September 25, 2003Publication date: April 1, 2004Inventor: Yasuhiro Unosawa

Publication number: 20040061739Abstract: An ink-jet printer (100) has a movable print carriage (120) carrying a printhead (130) which is supplied with ink from a fixed reservoir (150) via an intermediate portion (135) mounted on a second movable carriage (140). The intermediate portion (135) is connected to the reservoir (150) by first tubing (151), and to the printhead (130) by second tubing (152), the second carriage (140) serving to decouple forces from the print carriage (120) which would lead to deterioration in print quality. The carriages (120, 140) are moved along common longitudinal guides (123, 124) by a drive belt (160). The carriages may be arranged end-to-end or partially overlapping; alternatively one (840, 940) may straddle or enclose the other.Type: ApplicationFiled: October 21, 2003Publication date: April 1, 2004Inventors: Richard H.
