Patent number: 6519442Abstract: An apparatus for printing continuous paper wherein, when a paper uppermost portion sensor produces an unstable output due to the position of the paper in controlling the operation for raising or lowering a table for stacking the continuous paper, the output value is invalidated and the operation for raising or lowering the table is continued. The sensor detects the uppermost position of the paper on the paper table on which the continuous paper carried through a printer unit is folded by a guide member and is stacked, and a control unit controls a moving mechanism relying upon the sensor output to change the distance between the paper table and the guide member. When the sensor is producing an unstable output due to the position of the paper being stacked, the control unit works to continue the operation of the moving mechanism even when the sensor has detected the paper.Type: GrantFiled: July 2, 2001Date of Patent: February 11, 2003Assignee: Fujitsu LimitedInventor: Masato Matsuzuki

Patent number: 6339692Abstract: This invention relates to a printing device that performs fixation after transfer, and which prevents the occurrence of no transfer even when feeding the paper backward starting printing from the next page after the final page. This printing device comprises image-formation units (3, 4) that transfer a toner image, a fixation unit (5), and a control unit (10). The control unit (10) control adjustment of the moisture content on either the final page or leading page. In order to do that, it lowers the fixation energy of the fixation unit (5) for the final page. There is a moisture-adjustment mechanism (16) that reduces the moisture content of the leading page. Heat energy is applied to the leading page by the fixation unit (5). This reduces the difference in the amount of shrinkage between the final page and the leading page, and prevents wrinkling of the leading page.Type: GrantFiled: December 26, 2000Date of Patent: January 15, 2002Assignee: Fujitsu LimitedInventors: Hiroaki Yoshida, Masato Matsuzuki, Katsumi Adachi, Yoshikazu Yamamoto, Daisuke Fujii, Takashi Inui, Yukitoshi Takano

Patent number: 5722003Abstract: In a multicolor electrostatic recording apparatus in which two or more different color toner images are superimposed by respective electrostatic recording units, each of the electrostatic recording units includes an electrostatic latent image carried, a developer for developing an electrostatic latent image formed on the carrier with a color toner, and a detector for detecting a density of the developed image on the basis of a detecting mark which is formed on the carrier as a part of the latent image and developed by the developer. A discriminator which compares the density data with an optional desired density value to discriminate whether the density data falls in an allowable range. A controller for feed-back controlling at least one parameter for determining the density of the developed image so that the density comes to be in the allowable range, when the density falls out of the allowable range.Type: GrantFiled: November 28, 1995Date of Patent: February 24, 1998Assignee: Fujitsu LimitedInventors: Eiji Suzuki, Hitoshi Yoshii, Masato Matsuzuki, Hideyuki Shimobuchi, Shigeo Ishida
