  • Patent number: 10705453
    Abstract: An image forming apparatus includes a toner container attaching unit to which a toner container is to be attached, the toner container attaching unit including an apparatus-side terminal that comes into contact with a container-side terminal of the toner container and an apparatus-side coupling that engages with a container-side coupling of the toner container, and a control unit. The control unit is configured to execute a first process to acquire information of the toner container via the apparatus-side terminal, and cause the apparatus-side coupling to be rotated based on a result of the first process.

  • Patent number: 8027598
    Abstract: When copying control (copying/printing job) is finished, the main CPU checks whether the scanner control is being executed in the scanner portion. If the scanner control is not being executed, the main CPU checks whether there is any scanner control executing request. If there is no scanner control executing request, the main CPU locks a scanner control resource, reads out a count value of a toner residual amount stored in a non-volatile RAM, renews the control information of EEPROM of the toner cartridge through an interface, releases the lock of the scanner control resource and finishes the copying operation.
