    摘要： This invention provides a printing apparatus which controls to inhibit any inadvertent write to a memory in an expendable so as to securely manage the exchange timing and the like of the expendable. For this purpose, the expendable such as a toner cartridge or the like comprises a rewritable nonvolatile memory (21) which holds information indicating whether or not its service life has expired. When the toner cartridge is attached to the printing apparatus, it is ready to communicate with a printer engine controller in the printing apparatus, and write to the nonvolatile memory (21) can be made in accordance with an instruction from a control unit. A lock functional unit (21a) writes information indicating write inhibition at a predetermined address in the nonvolatile memory (21), thus inhibiting write to the address position that stores the information indicating whether or not its service life has expired.

    摘要： In an image forming apparatus mountable a detachable unit mounting a memory in a main body of the apparatus, a memory-access-reservation control unit for accepting a request of an access with respect to a nonvolatile memory provided in a process cartridge in which a photosensitive drum, a toner and the like are integrated is provided in an engine control unit. When there is a request of an access with respect to the nonvolatile memory from a printer controller, the memory-access-reservation control unit accesses the nonvolatile memory in accordance with the request of the access. Upon completion of the access, the fact is notified to the printer controller. In response to the notification, the printer controller requests transmission of read information or confirms that a writing operation has been normally ended, by communicating with the engine control unit.

    摘要： It is an object of the invention to make it possible to extend a degree of freedom on designing and further improve the reliability when an output control is performed according to a status change of a printer engine. When there is the status change of the printer engine, whether an output monitoring timer of a CCRT signal is OFF or not is detected. If NO, whether the counting operation of the timer has been finished or not is discriminated. When the counting operation of the timer is finished, the timer operation is stopped. After the timer operation was stopped, the CCRT signal is set to “true”. When a status request command from an image controller is received, a transmission preparation of a current state of the printer engine is started. After completion of the transmission preparation of the status signal, an SBSY signal is set to “true” and the CCRT signal is set to “false”. After that, the timer is set to a predetermined value and the counting operation is started.

    摘要： An engine control unit and corresponding method of controlling the engine in which the engine control unit receives a print reservation command for plural pages prior to a print request command from a printer control unit. When the engine control unit received the print reservation command for the plural pages, it is judged whether or not a sheet feed operation of recording sheets can be performed. When it is judged that the recording sheets can be fed, the recording sheets are fed and transported to a predetermined position on a transportation path with a minimum constant interval corresponding to the sheet size by sheet feed rollers or transportation rollers, then printing operation is performed according to the print request command.
