The following steps are performed in connection with a photodiode circuit: a) resetting the photodiode circuit; b) determining when a photodiode voltage changes in response to illumination to reach a threshold; and c) updating a counter in response to the determination in step b). The steps a) to c) are repeated until an end of a measurement period is reached. The value of the counter at the end of the measurement period is then output to indicate an intensity of the illumination.

Systems, methods, and computer-readable media are provided. Some embodiments include receiving, at a computing system from an image processing device, a request to access a resource. The computing system obtains information that identifies a component installed on the image processing device as a replacement component. The computing system obtains information indicating a count value of a counter associated with the component. The computing system determines whether the counter has been reset based on the information indicating the count value of the counter. In response to determining that the counter has not been reset, the computing system sends, to the image processing device, the resource including information for presentation as an interface element in a graphical user interface on a display of the image processing device, the interface element enabling a user to reset the counter by selecting the interface element.

An image forming device that executes an image forming program for real-time mechanical control and another program, using a single cache memory for the image forming program and said another program. The image forming device includes: a cache lockdown unit that executes a cache lockdown to lock down a storage area of the cache memory that stores at least a portion of the image forming program necessary for image formation processing; and a print unit that executes the image formation processing while the storage area is locked down.

A display control apparatus includes an acquisition unit that successively acquires plural images, a display unit that displays the images on a display in an automatic image switching mode by successively switching from one to another the images acquired by the acquisition unit, a suspending unit that temporarily suspends the automatic image switching mode without the acquisition unit stopping acquiring the images if an instruction to suspend the automatic image switching mode is provided, and a resuming unit that resumes the automatic image switching mode that has been temporarily suspended by the suspending unit.

In accordance with an embodiment, the image forming apparatus comprises a display section, a connection section and a controller. The connection section connects with a device having a storage section. The controller detects connection and disconnection with the connection section and does not display a first screen displayed on the display section due to the connection with the device if the disconnection is detected.

An example image forming apparatus includes a scanner including a feeding device, a multi-feed detection sensor to detect an event corresponding to a multi-feed of a paper fed from the feeding device, a return device to return a target paper detected as the event, a user interface device, a processor, and a memory to store instructions executable by the processor. The processor is to execute the instructions to control an operation of the return device based on the setting information of the multi-feed detection sensor input through the user interface device.

An image forming apparatus includes a data selector circuit that receives an instruction of a selection range from a serviceman via the operation unit and the display unit, and automatically selects data to be backed up in the external storage device in the selection range out of the pieces of data, a backup circuit that backs up the data selected by the data selector circuit out of the pieces of data in the external storage device being connected, and sends the data unselected by the data selector circuit to the database server for backup, and a restoring circuit that restores the data backed up in the external storage device in a first storage after replacement for the maintenance, then receives the data backed up in the database server, and restores the data in the first storage after replacement for the maintenance without the serviceman.

An information processing device includes: a replacement processing unit that replaces, when a second time as a time until a distance between a second terminal device that has transmitted a second information processing request having a lower priority and the information processing device becomes equal to or smaller than a predetermined value is shorter than a first time as a time until the distance between a first terminal device that has transmitted a first information processing request having a higher priority and the information processing device becomes equal to or smaller than a predetermined value, priorities for executing first information processing request and the second information processing request such that the second information processing request having the lower priority is processed earlier than the first information processing request having the higher priority.

An image forming apparatus includes a control portion. The control portion executes a print step, a determination step, a setting step, and a resuming step. In the print step, a print process is executed in which images of pages are printed in sequence based on image data including the pages. In the determination step, in a case where the print process has been suspended, it is determined whether a cause of the suspension of the print process is a particular cause. In the setting step, in a case where it has determined that the cause of the suspension of the print process is the particular cause, the resumption page is set in accordance with a user operation. In the resuming step, the print process is resumed from the resumption page set in the setting step.

An image forming apparatus includes a printing unit that performs printing based on a job, a setting unit that sets a setting specifying whether billing is to be performed for printing performed by the printing unit, and a control unit that, in a case where printing performed by the printing unit is interrupted due to occurrence of a job interruption event, if a setting specifying that billing is not to be performed is set by the setting unit, executes cancellation of the job when a predetermined time period elapses without a cause of the interruption being cleared and, if a setting specifying that billing is to be performed is set by the setting unit, does not execute the cancellation.
