An image forming apparatus which is capable of reducing input errors in network settings. The image forming apparatus has a plurality of network I/Fs and connects an image formation control apparatus to one of the plurality of network I/Fs. A display control unit controls display on a screen relating to network settings on the image forming apparatus. Based on selection of a network I/F to which the image formation control apparatus is to be connected, the display control unit determines what to display on the screen relating to network settings on the image forming apparatus.

Image forming apparatus equipped with communication function, control method therefor, and storage medium

A printing system includes a printing control apparatus and a printing apparatus. The printing apparatus includes a receiving unit that receives data transmitted from the printing control apparatus, and a power source control unit that causes the printing apparatus to enter a first power saving state or a second power saving state. The printing control apparatus includes an acquisition unit that acquires a power state of the printing apparatus, and a control unit that causes the printing control apparatus to enter an OFF state in a case where a acquired power state is the first power saving state, and causes the printing control apparatus to enter a power saving state where a wake-up packet for recovering the printing apparatus from the second power saving state can be transmitted in a case where the acquired power state is the second power saving state.

An information processing apparatus operable in a standby mode and in a sleep mode. The information processing apparatus comprising a sleep unit and, a power-off unit. The sleep unit configured to shift the information processing apparatus into the sleep mode if a first time has elapsed in the standby mode. The power-off unit configured to turn off the power supply of the information processing apparatus if a second time has elapsed in the sleep mode and configured to turn off the power supply of the information processing apparatus at a specified time. The power-off unit configured to turn off the power supply of the information processing apparatus without waiting for the second time if the information processing apparatus has been started after the time specifying power-off processing.

Information processing apparatus and method for controlling the information processing apparatus

There is provided an original conveying apparatus for conveying an original to an image reading section of an image forming apparatus, which is capable of preventing the number of times of writing to a nonvolatile storage medium that stores a correction value for the light emission amount of an optical sensor from exceeding a limited number of times even when adjustment of the light emission amount of the optical sensor is carried out frequently, reducing as far as possible the number of times of writing data to the storage medium that can store such data a limited number of times, thereby eliminating the occurrence of inconvenient situations such as it being impossible to maintain proper output processing, and lengthening the lifetime of the storage medium. Writing of the correction value for the light amount of the light-emitting section of the optical sensor to an EEPROM is carried out if the correction value has changed by at least a predetermined amount relative to the value before adjustment but is not carried out if the correction value has not changed by at least this predetermined amount relative to the value before adjustment.

Original conveying apparatus, light amount adjustment method for light-emitting section thereof, image forming apparatus, control method therefor, storage control device, storage control method, and storage medium

An image recording apparatus provided with: a stacking tray for stacking originals thereon; a feeding device for feeding the originals on the stacking tray one by one; a reading device for reading the information of the originals fed by the feeding device; a storing device for storing the read information thereon; an image forming device for forming an image on a sheet based on the read information; and a control device for effecting a control of reading and storing a plurality of originals corresponding to the storage capacity of the storing device, and forming an image on the sheet based on the storage of the storing device, and effecting a control of forming an image on a sheet each time the image of a remaining original is read by the reading device.

Image recording apparatus provided with an original reading apparatus

In an original-feeding device and method, originals are conveyed from an original-tray on which a bundle of originals can be mounted to an original-reading mount. A control unit controls an original-conveying operation so as to separate and feed originals from the bundle of originals mounted on the original-tray onto the original-reading mount either from an uppermost original or from a lowermost original. The control unit can control the original-conveying operation to juxtapose two consecutive originals on the original-reading mount irrespective of whether the originals are fed from the uppermost or lower-most original. In addition, the number of originals in the bundle can be counted if certain conditions exist.

A host computer 104 at a remote administrative site receives a jam code and the number of accumulated copies made from a photocopier 100 at which jamming has occurred, an accumulated jam curve is calculated based on the received data, a certain filtering process is performed, the risk of jamming is estimated based on the filter output and a membership function between the filter value and risk, thus judging whether or not to visit the user.

Administrative device for image forming apparatus

An automatic document feeder provided with a pre-feed function, in which during reading an originals, a succeeding original is fed to an entry of a reading station and keep it there includes an original stacking tray for stacking originals; a separator for separating a single original from the stacked originals on the stacking tray; a driver for driving the separator; a feeder for feeding the original separated by the separator; a second driver for driving the feeder; a conveyer for conveying the original fed by the feeder; a third driver for driving the conveyer; and a controller, provided with detector disposed downstream of the feeder, for stopping the original adjacent an inlet of the conveyer.

Automatic document feeder

The present invention provides an original convey apparatus with an original tray on which originals are rested, a conveyor for conveying the original on the original tray, a last original detector for detecting the fact that all of the originals on the original tray are conveyed, and original size information detector. Wherein an original detector position for the last original detection is changed on the basis of original size information.

Original convey apparatus with last original detection sensor

The present invention provides an automatic original feeding apparatus comprising first rotary supply means for supplying a sheet original, second rotary supply means disposed at a downstream side of the first supply means to supply the sheet original, control means for rotating the second rotary supply means reversely to return the sheet original toward an upstream side by a small amount, retract means for directing a trailing end of the returned sheet original out of a sheet path connecting between the first and second rotary supply means, controlling means for controlling the first rotary supply means to cause the first rotary supply means to feed a next sheet original until a leading end of the next sheet original is overlapped with the trailing end of the first sheet original, information means for the kind of sheet originals, and means for changing a return amount of the sheet original effected by the controlling means, in accordance with the kind of the sheet original from the information means.

Automatic original feeding apparatus of original side-by-side mount type

In the present invention, a plurality of states of a transfer motor and those of a feed motor in a paper sheet transferring device located in a copying machine or the like are detected, and a plurality of sets are generated on the basis of the states according to fuzzy membership functions and fuzzy rules to determine the speed of the feed motor. A position of a center of gravity of a single area obtained by ORing the plurality of generated sets is determined as a control variable of the feed motor.
