摘要: An image forming apparatus includes an apparatus body, a toner cartridge, a replaceable part, an apparatus body memory, and a controller. The replaceable part includes a replaceable part memory storing therein extended-use allowance-and-restriction information. The extended-use allowance-and-restriction information indicates one of allowance information and restriction information. The extended use is defined as use of the replaceable part even after the replaceable part exceeds the remaining life indicated by the life information stored in the apparatus body memory. The apparatus body memory stores life information indicating remaining life of the replaceable part. In a case where the controller determines that the extended-use allowance-and-restriction information indicates the restriction information, the controller is configured to restrict the extended use of the replaceable part. In a case where the controller determines that the extended-use allowance-and-restriction information indicates the allowance information, the controller is configured to allow the extended use of the replaceable part.

摘要: An image forming apparatus includes: a casing having an opening; a cover for opening and closing the opening; a cartridge attachable to the casing through the opening; and a controller. The casing includes a first memory. The cartridge includes a second memory storing consumption state information representing a consumption state of the cartridge. The controller performs: determining whether the cartridge attached to the casing is unused; storing, when the attached cartridge is unused, the consumption state information acquired from the second memory in the first memory; determining, when the image forming apparatus is powered on or the cover is closed, whether the consumption state information in the first memory and the consumption state information in the second memory match; permitting use of the cartridge when the two sets of consumption state information match; and prohibiting use of the cartridge when the two set of consumption state information does not match.

摘要: An image forming device is provided. The device includes a main body which includes a main controller controlling operations of the image forming device, a consumable unit mounted on the main body to enable communication with the main controller, and a CRUM chip which is provided in the consumable unit and stores usage information of the consumable unit and characteristics information. The main controller and the CRUM chip transmit and receive signals which include data and integrity detection data between each other. The integrity detection data is generated by accumulating and reflecting integrity detection data included in a previous signal.

摘要: A communication method is provided between a chip and an imaging device. Accordingly, the chip receives a clock pulse signal from the imaging device via a clock line; and receives a READ instruction from the imaging device via a data line. Within one clock pulse signal period, the chip transmits at least one bit of implicit data and one bit of master data that are stored in an internal memory to the data line within different time slots, respectively, and the imaging device collects data from the data line while the chip is transmitting the master data to the data line. Further, the chip receives a WRITE instruction from the imaging device via the data line, wherein the chip receives master data sent from the imaging device, writes the master data into the memory arranged in the chip, and updates the implicit data stored in the memory.

摘要: An image forming apparatus includes an image forming apparatus body and a unit. The unit is installed on the image forming apparatus body and includes a wireless tag. The image forming apparatus body includes a first power supply unit, a setting unit, a second power supply unit, a generating unit, and a communication unit. The second power supply unit generates a second value of voltage set in the setting unit. The generating unit uses the first power supply unit as a power source and generates a first signal for transmission to the wireless tag. The communication unit uses the second power supply unit as a power source, generates a second signal having amplitude in proportion to the second value set in the setting unit based on the first signal, and transmits the second signal to the wireless tag by wireless.
