Patent number: 7537205Abstract: A size storing unit stores a size of a ring member for binding stacked sheets. A range determining unit determines whether a thickness represented by input thickness information is larger than a minimum total thickness of sheets allowed to be bound with a ring member having the stored size and equal to or smaller than a maximum total thickness of sheets that can be bound with the ring member. When it is determined that the thickness represented by the thickness information is equal to or smaller than the minimum total thickness or larger than the maximum total thickness, a setting unit sets the size stored in the size storing unit to a different size.Type: GrantFiled: September 13, 2007Date of Patent: May 26, 2009Assignee: Ricoh Company, Ltd.Inventors: Tadashi Nagata, Nobuaki Tomidokoro, Tsuyoshi Endoh, Motoyuki Katsumata, Kohji Ishikura, Akira Miyazaki, Aritaka Hagiwara

Patent number: 7518742Abstract: An image processing apparatus includes a controlling unit that controls all units of the image forming apparatus, a reading unit that reads an image, a processing unit that generates image data based on the image read, a recognizing unit that recognizes a ground tint pattern in the image read, and a detecting unit that detects an abnormality in the recognizing unit. When the recognizing unit recognizes a ground tint pattern in an image read, the controlling unit controls the processing unit to perform a special processing on the image. When the detecting unit detects an abnormality in the recognizing unit, the controlling unit controls the image forming apparatus according to the abnormality.Type: GrantFiled: November 17, 2005Date of Patent: April 14, 2009Assignee: Ricoh Company, Ltd.Inventors: Shiho Toyonori, Tsuyoshi Endoh, Takeshi Kowada, Nobuaki Tomidokoro

Patent number: 7502141Abstract: In an image forming device, a ground-tint detection unit detects a ground-tint pattern in an original image based on image data output from an image reader unit. An image invalidation unit outputs a processed image data that makes the image data of the original image illegible, when the ground-tint pattern in the original image is detected. A resolution setting unit allows a resolution of the image reader unit to be higher than a minimum resolution needed for detection of a ground-tint pattern and stored in a memory unit.Type: GrantFiled: November 30, 2005Date of Patent: March 10, 2009Assignee: Ricoh Company, Ltd.Inventors: Takeshi Kowada, Shiho Toyonori, Nobuaki Tomidokoro, Tsuyoshi Endoh

Patent number: 6240261Abstract: An image forming apparatus supervising system includes a problem detecting device in each of image forming apparatuses, which detects a problem to be reported to a central control apparatus as a service person call when the problem occurs in the image forming apparatus. A first copysheet number storing device is employed to store a total number of copysheets having been copied before a current occurrence of the problem occurs in an image forming apparatus. A second copysheet number storing device is also employed to store a number of copysheets having been copied before a last occurrence of the problem. The problem is reported only when a difference between the numbers of copysheets stored in the first copysheet number storing device and the second copysheet number storing device exceeds a predetermined level so that an erroneously detected problem can be avoided from being reported as the service person call.Type: GrantFiled: September 30, 1999Date of Patent: May 29, 2001Assignee: Ricoh Company, Ltd.Inventor: Nobuaki Tomidokoro

Patent number: 5784663Abstract: A control system for collectively supervising a plurality of copiers or similar image forming apparatuses connected to a control device by communication lines with or without the intermediary of communication control units. To down-load data relating to image formation, the control device determines whether or not a copier of interest is in an inoperative state and, if it is in an inoperative state, automatically sends the data to the copier via a telephone line, an exchange, and a communication control unit. This data is written to storing means built in the copier. To up-load data relating to image formation, the control device causes each copier to automatically send the data stored in the storing means and stores the data in memory means. Up-loading is effected at an optimal time other than the time when the copier is performing an automatic adjustment, is in use, or is quite likely to be used.Type: GrantFiled: March 7, 1997Date of Patent: July 21, 1998Assignee: Ricoh Company, Ltd.Inventors: Masayuki Hayashi, Yoshihiro Mitekura, Koichi Kanaya, Masato Terao, Toshiya Tagawa, Nobuaki Tomidokoro, Masahiro Kitayama, Osamu Kizaki, Yasuo Kawada, Kazuyuki Nakahara, Tomofumi Harada, Yasunari Hashimoto
