An image forming device includes an image forming unit performing image forming, a notifier playing a voice guidance of a service related to image forming for a user, a display that displays a message to a user, and a controller controlling the image forming unit, the notifier, and the display. The controller allows the notifier to start the voice guidance to perform image forming services. When the service is for the first time to a user, the controller allows the display to transition to the next screen after the voice guidance is played to the end, and on the other hand, when the service is repeated for the second or subsequent times to a user, the controller allows the notifier to stop playing the voice guidance halfway after screen transition to the next screen becomes possible, and then the controller allows the display to transition to the next screen.

Image forming device

A reboot control system includes an information processing device and a reboot management device connected over a network. The reboot management device includes a first storage unit that stores device management information including information related to each information processing device, a reboot time setting unit that sets a reboot time, and a reboot time notification unit that transmits the set reboot time to each information processing device. The information processing device includes a reboot information acquisition unit that acquires the transmitted reboot time, and a reboot execution unit that executes a reboot at the acquired reboot time. The reboot time setting unit takes Into account a positional relationship of multiple information processing devices existing in a predetermined neighboring relationship to set the reboot times of the multiple information processing devices existing in the predetermined neighboring relationship to mutually different times.

Reboot control system

To provide a print data processing system, a printer, and a data processing indicating apparatus, for storing print data and a print history and notifying update of the print data, which is not necessarily registered separately in order to receive a notification of update. The printer stores name data of print data, identification data of a data processing indicating apparatus (or an external apparatus) that has sent storage indicating data of the print data, and identification data of a data processing indicating apparatus (or an external apparatus) that has sent print indicating data of the print data; judges if the print data is updated or not on the basis of the stored data; and notifies each data processing indicating apparatus (or the external apparatus) that has sent print indicating data of the print data of update of the print data.

Print data processing system, printer, and data processing indicating apparatus

A monitoring device includes: a setting storing section for storing beforehand a correspondence between identification information for identifying a data file, and a processing condition of the data file having the identification information; an extracting section for acquiring, as transmitted identification information, identification information of the data file transmitted to the information processing apparatus, and, as a transmitted processing condition, the processing condition of the data file transmitted to the information processing apparatus; a comparing section for determining whether a combination of the transmitted identification information and the transmitted processing condition matches the correspondence between the identification information and the processing condition stored in the setting storing section; and a notifying section for notifying a sender of the data file that there is no match, if so determined by the comparing section.

Monitoring device, system, method, and program for monitoring a data file and a processing condition used to process the data file

A digital image forming apparatus wherein at least when an occurrence of trouble that required automatic switching of the power witch to the OFF position during operation of the image output operation when it is detected by a trouble detector, the image data inputted for an image output operation is stored in an internal memory which ensures the memory content even with the power switch switched to the OFF position. After the trouble is settled, the image output operation is continued with respect to the image data stored in the internal memory by the image output unit. As a result, an idle operation for reinputting the image data to be outputted through visualization by, for example, a reading operation of the document image can be eliminated.

Digital image forming apparatus

A cleaning unit used for cleaning the surface of a recording medium in an image forming apparatus, the cleaning unit having a head being moved so as to contact with and separate from the recording medium on the basis of the assessment of preset image forming conditions such as paper size, document size, and copy magnification, and a control section for moving the cleaning head at a detected appropriate time, wherein the cleaning head is released so as to avoid the dispersion of toner that is likely to spoil the image.

Cleaning unit

An electrophotographic apparatus is provided with a fixing device having the first through third fixing rollers for forming the first fixing section by contacting the first and second fixing rollers as well as forming the second fixing section by contacting the second and third fixing rollers, the first fixing section being temperature-adjusted in relation to a first copying mode, the second fixing section being temperature-adjusted in relation to a second copying mode. Either the first or second fixing section is temperature-adjusted according to the order of priority in such a manner that after the completion of the temperature adjustments, temperature adjustments with respect to the other fixing section is successively carried out.

Electrophotographic apparatus having two fixing sections and control

An apparatus (10) for controlling a location of an image on a conductive transfer belt (15), the conductive transfer belt having a hole (14) and for transferring a plurality of images formed on a photosensitive belt (11), the apparatus includes a transparent photosensor (16) for sensing a location of the hole and for supplying a signal indicating the sensed location, and a microprocessor (CPU) for controlling a relative location of the conductive transfer belt with respect to the photosensitive belt, the microprocessor serving to transfer a plurality of images formed on the photosensitive belt onto different locations on the conductive transfer belt in accordance with the signal.

Apparatus for controlling image location on medium

A fixing unit for an image forming apparatus, for fixing a toner image transferred onto a recording sheet, which includes a fixing section having a heat roller and a pressure roller, includes a detector for detecting the time when the recording sheet reaches between the heat roller and the pressure roller; and a controller for controlling the moving speed of the fixing section to be gradually decreased when the recording sheet reaches the fixing section.

Fixing unit for controlling the moving speed of the fixing section
