  • Patent number: 10073396
    Abstract: An image forming apparatus includes an information obtainer, a memory, a candidate determining unit, and an image forming device. The information obtainer obtains feature information from the target recording medium. The memory stores at least one set of recording medium information regarding the target recording medium associated with the feature information and at least one set of image forming condition information corresponding to the recording medium information. The recording medium information is identification information. The candidate determining unit determines a candidate recording medium information from the recording medium information stored in the memory based on the feature information of the target recording medium obtained by the information obtainer.

    Abstract: A multi-function printer main body has a copy function. A remote terminal conducts various kinds of copy settings or instructions to start copy. An execution button is provided in the multi-function printer main body. When the execution button is operated in normal time, copy is executed with the default settings. When copy is executed by inputting copy settings on the remote terminal side, copy can be executed again with the copy settings used for the last time by operating the execution button until a predetermined period of time passes. Therefore, in a case of executing copy with the default settings or repeatedly executing copy with the same settings as the settings used for the last time, a user's work burden can be reduced because it is sufficient for the user to operate the execution button 38.

  • Patent number: 8773689
    Abstract: A method starts when a print job is received from a workstation. The print job includes user printing options and an identification of an initial printer. The method ranks the abilities of the available printers to process the print job to identify the best printer for the print job according to, among other items, printer proximity. If the initial printer identification creates a print policy violation, the method presents a question/statement to the workstation (to the user through the workstation) regarding whether the print job should be redirected to the best printer and provides an automated resubmit option at the workstation. If the resubmit option is activated, the method automatically submits the print job to a different available printer, without requiring the user to manually input the printing options.

  • Patent number: 8761616
    Abstract: A controller determines a state of a switch unit based on a potential difference between a power supply side and a load side of the switch unit. Alternatively, when an electronic device is in a first operating state, the controller determines a state of the switch based on a result of a first detection unit. When the electronic device is in a second operating state that a power consumption of the device is lower than that in the first operating state, the controller determines the state of the switch based on a result of a second detection unit.

    Abstract: An image forming apparatus receives setting of an object to be adjusted, on an adjustment object selection screen when selecting an adjustment mode. After the object to be adjusted is set, camera(s) photograph(s) the object to be adjusted so that the image forming apparatus obtains photographed data of current object to be adjusted. Next, the apparatus searches photographed data of the object to be adjusted in the ideal state thereof from the database. Name of the object to be adjusted and related information in the photographed data agree with those of the photographed data of current object to be adjusted. The higher ranked related information is preferentially searched and it is determined whether or not pieces of the higher ranked related information thus preferentially searched agree with each other.

  • Patent number: 8712257
    Abstract: An image forming system includes first and second generation units, a setting unit, and a prognosis unit. For a monitoring item whose detection values, being detected during an image forming operation in an image forming apparatus in which a trouble occurred within a predetermined time period after an operating condition was changed, were changed to an abnormal state, the first generation unit generates characteristic information indicating a variation state of the detection values. The setting unit sets criterion information to predict occurrence of a trouble, based on the generated characteristic information. The second generation unit generates, for the monitoring item corresponding to the set criterion information, characteristic information indicating a variation state of detection values in a target image forming apparatus.

    Abstract: A light source is provided in the casing and emits a light beam for forming an image. A first sensor receives the light beam emitted by the light source and outputs a light reception signal. A cover opens and closes relative to the casing. A shutter prevents the first sensor from receiving the light beam when the cover is at an open position, and allows the first sensor to receive the light beam when the cover is at a closed position. A controller is configured to: execute a lighting process of lighting the light source; execute a first determining process of determining whether the light reception signal is outputted from the first sensor, in response to the lighting process; and determine that the cover is at the open position upon determination in the first determining process that no light reception signal is outputted.
