An information storage device installed in a removable device configured to be removably installed in an image forming apparatus body, includes: an information storage unit that stores information communicated between the image forming apparatus body and the removable device; a terminal that comes in contact with a body side terminal; and a substrate that holds the information storage unit and the terminal and includes a hole configured to be engaged with a protruding section installed in the image forming apparatus body. The terminal includes a plurality of terminals each including one of a plurality of metallic plates arranged in a transverse direction thereof. An earth terminal, which comes in contact with a body side earth terminal formed in the protruding section, is formed in the hole. The hole is disposed at a position sandwiched between two metallic plates among the plurality of metallic plates.

An image forming apparatus is provided with USB sockets on front and back sides, and includes a determining unit for determining whether or not a USB device inserted to a front side USB socket 184 is a function enhancement device, and a control unit making, when it is determined by the determining unit that a function enhancement device is inserted to the front side USB socket 184, the USB device unusable and making, when it is determined that a USB device other than the function enhancement device is inserted, the USB device usable. Thus, it is possible to prevent a USB wireless LAN adapter or the like from being used constantly connected to the front side USB socket and thereby to reduce possibility of USB wireless LAN adapter of being damaged or removed.

An image forming apparatus, including: an image former that forms an image on continuous form paper; and a hardware processor that calculates a paper cost for a print job of the continuous form paper, on the basis of a distance of the continuous form paper conveyed from a start to an end of the print job.

A system for customizing settings of an electronic device includes a replaceable component having an optical member for receiving optical energy. The optical member has an optical characteristic for modifying an amount of the optical energy that leaves the optical member relative to an amount of the optical energy received by the optical member. A support is located on an outer casing of the electronic device and the replaceable component is mountable on the support. The system further includes an optical sensor including a detector positioned to receive the amount of the optical energy leaving the optical member when the replaceable component is mounted on the support. A controller determines one or more predetermined settings to be applied to the electronic device based at least upon the amount of the optical energy received by the detector.

An image forming apparatus with a detachable fixing device that is capable of printing with high quality without printing wastefully. A storage unit stores identification information about a fixing device in association with an attribute of a sheet that is printable with the fixing device concerned. A control unit executes printing when the storage unit does not store an attribute of a sheet corresponding to a fixing device that is currently attached to the image forming apparatus. The control unit determines whether to execute printing according to an attribute of a sheet used in printing and an attribute of a sheet stored in the storage unit when the storage unit stores the attribute of the sheet corresponding to the fixing device that is currently attached to the image forming apparatus.

An image forming apparatus includes one or more controllers; and an image former having a detachable fixing unit, wherein the one or more controllers acquire fixing unit information on a fixing unit being attached to the image former, and execute a predetermined process, based on the acquired fixing unit information.

Disclosed is a non-transitory recording medium storing a computer-readable program, the program causing the computer to execute: acquiring a log from an image forming apparatus; determining whether a printing interruption time for each printing interruption exceeds a reference time based on the log acquired in the acquiring; creating display data in a display manner that allows recognition of a proportion of the printing interruption determined to exceed the reference time in the determining; and outputting the display data created in the creating.

An image forming apparatus includes a conveyance mechanism, a wireless tag communication device, an image forming mechanism, a fixing device including a heating device to heat a medium passing between fixing and pressing members, and a moving mechanism by which a distance between the fixing and pressing members can be changed, and a processor to control the conveyance mechanism to convey a medium, control the communication device to perform a writing process on a tag attached to the medium, and control the forming mechanism and the fixing device to perform a forming process on the medium. The processor controls the fixing device to set the distance at a first distance during a first period before a timing corresponding to completion of the writing process and at a second distance less than the first distance during a second period after the timing.
