Abstract: A controller performs: acquiring payment deadline information from a server via a communication interface, and storing the payment deadline information in a memory, the payment deadline information including a payment deadline of a contract fee for an image forming apparatus that is usable by setting a contract; determining whether communication with the server is possible; in response to determining that communication with the server is not possible, determining whether a real-time clock is operating; in response to determining that the real-time clock is operating, acquiring time information from the real-time clock and determining whether the time information is past the payment deadline by referring to the payment deadline information stored in the memory and the time information acquired from the real-time clock; and in response to determining that the time information is past the payment deadline, disabling at least part of functions of the image forming apparatus.

Abstract: An image-reading device is provided that includes a reading component configured to read a document, a document holding portion, a detector detecting a position of the document holding portion, a power supply device that supplies power to the reading component, and a power supply control device that controls power supplied by the power supply device to the reading component. The power supply control device determines whether a change in the position of the document holding portion has occurred based on the position of the document holding portion detected by the detector. When a change in position is detected and the image reading device is not performing document reading, the power supplied to the reading component is reduced. If a change in position is detected while the image reading device is performing document reading, the power supplied to the reading component is maintained.

Abstract: In an image processing apparatus, a power switcher starts supplying power in a second mode in which the power is supplied to a controller but not supplied to an image processor, when a state in which the power switcher receives no power is changed to a state in which the power switcher receives power. When a state in which no power is supplied to the controller is switched to a state in which power is supplied to the controller in the second mode and when the power switcher is receiving no power from a commercial power source, the controller, based on particular information, switches, before a first processing, a power supply mode from the second mode to a first mode in which no power is supplied or switches the power supply mode from the second mode to the first mode after the first processing.

Abstract: In a reading apparatus, a control device determines whether a predetermined state is detected based on a signal outputted from a sensor device. The control device sets a first-interface control device into a normal state when a transition condition is satisfied while the first-interface control device is being in a power saving state. The transition condition includes a condition that the predetermined state is detected. The control device maintains the first-interface control device in the power saving state when the transition condition is not satisfied while the first-interface control device is being in the power saving state, regardless of whether a receiving device receives first input.

Abstract: A copying apparatus with a color copy function includes: a reading unit configured to read images on a document; an input unit configured to input commands from a user; an image forming unit configured to form a mark for image adjustment, perform an image adjustment on the image read by the reading unit based on the formed mark for image adjustment and print the adjusted image; and a judging unit configured to trigger the image forming unit to form the mark for image adjustment if the command for executing color copying is input into the input unit.

Abstract: An image forming system for communicably connecting a data processor and an image forming apparatus can include a registration unit for registering a print job based on a print request, a printing unit for conducting print processing based on a print job registered in the registration unit, an authentication unit for, when the print job is a locked job with an unlocking condition, prohibiting print processing of the locked job until the unlocking condition is fulfilled, and a prohibition unit for prohibiting print processing of a normal job, which is registered in the registration unit after registration of the locked job, without the unlocking condition.

Abstract: A printer includes a feed unit; an image forming unit, which executes double-side printing; an acceptance unit, which accepts an execution command of either continuation printing and reprinting if double-side printing is stopped and a first recording medium with only a first side image printed thereon exists in the conveying path of the printer; and a control unit, which prints only the unprinted second side image, if a continuation printing command is entered and the control unit reprints the first side image on a second recording medium and also prints the unprinted second side image on the second recording medium, if a reprinting command is entered.

Abstract: An MFP has: a receiving section receiving a FAX reception request and FAX data; and an image forming section capable of forming a color image. When an execution condition for acquisition processing of acquiring information used for adjusting the image forming section is satisfied, the MFP executes the acquisition processing in response to a trigger defined as start or end of processing of a print job. Further, when receiving a FAX reception request in a state that the execution condition for acquisition processing is satisfied, the MFP notifies function information concerning the function of the image forming section (e.g., information indicating that color image formation is not available), to a FAX device of sender.
