Patent number: 10308452Abstract: An image forming apparatus includes a stacking unit, an access detecting unit, a malfunction detecting unit, a counting unit, and a process deciding unit. The stacking unit receives, as stacked, a recording material. The access detecting unit detects an access to the stacking unit by an operator. The malfunction detecting unit detects that a conveyance malfunction of the recording material has occurred on a conveying path guiding the recording material supplied from the stacking unit. The counting unit counts, after the access detecting unit detects an access to the stacking unit by the operator in a state that the malfunction detecting unit does not detect that the conveyance malfunction has occurred, the number of the conveyance malfunction detected by the malfunction detecting unit. The process deciding unit decides a process to address the conveyance malfunction based on the number of the conveyance malfunction counted by the counting unit.Type: GrantFiled: February 26, 2018Date of Patent: June 4, 2019Assignee: Canon Kabushiki KaishaInventor: Michio Sugano

Patent number: 9802778Abstract: An image forming apparatus may comprise the following elements. A stacking unit in which a sheet is stacked. A conveyance unit conveys the sheet. A time-counting unit counts a conveyance time from when the conveyance unit starts to convey the sheet until the sheet arrives at a predetermined position on a conveyance path. A determination unit determines that over stacking has occurred, if the conveyance time of the sheet exceeds a first over stacking threshold value.Type: GrantFiled: June 16, 2016Date of Patent: October 31, 2017Assignee: Canon Kabushiki KaishaInventors: Ken-ichiro Isobe, Michio Sugano

Patent number: 8385757Abstract: An image forming apparatus includes a reception unit, an image forming unit, a drive unit, a detection unit, a prediction unit, and a control unit. The image forming unit forms an image based on image information received by the reception unit. The drive unit controls an imaging forming unit drive. The detection unit detects temperature within the image forming apparatus. The prediction unit predicts a transition of temperature within the image forming apparatus and an image formation time based on the image information and the temperature within the image formation unit. The control unit is responsive to detected temperature and predicted image forming time. The control unit switches between image forming modes and controls the image forming apparatus to form an image in a short image forming time.Type: GrantFiled: December 9, 2010Date of Patent: February 26, 2013Assignee: Canon Kabushiki KaishaInventor: Michio Sugano
