Note that when the activation mode is notified immediately after S405 or in S406, the storage in the nonvolatile area in S203 is not necessary. In this case, unless the activation mode is notified immediately after S205 or at the earliest possible timing of S406, it is difficult to switch the activation process of the printer apparatus 4.
  • the initial operation is not changed when the power-off period is long and the initialization operation of the printer device 4 is required. Can be.
  • the printer device 4 may be provided with a timer for measuring the power-off period so that the printer device 4 measures the power-off period.
  • the printer device 4 is normally activated, so the controller 1 does not need to be activated at high speed.
  • a threshold value determined by the printer device 4 is stored in advance in the nonvolatile memory 105 of the controller 1 and, when the power is turned on (S405), it is determined whether or not the Off period exceeds the threshold value. Then, when the Off period exceeds the threshold, the high-speed activation of the controller 1 is stopped. In this way, the activation of the controller 1 may be matched with the activation of the printer device 4. *
  • the controller 1 may have a threshold value that matches the characteristics of self-confidence, calculate the power-off period in S405, stop the fast startup of the controller 1, and start up normally. In this case, the printer apparatus 4 is notified of the high-speed activation stop in S406, and the printer apparatus 4 is also activated normally.
  • the printer device 4 when the period during which the power is turned off exceeds the threshold value, the printer device 4 does not change the initial operation and the normal initial operation even if the activation mode of the controller 1 is the high-speed activation mode. To start normally. As a result, the entire image forming apparatus can be started at a high speed with a short-time power supply OFF, while when the power supply is off for a long time, the initialization operation of the printer apparatus 4 is executed without being changed. It is possible to initialize the state and prevent deterioration of the quality of the formed image. That is, both high-speed startup and high-quality image formation can be realized.
  • the present invention can take an embodiment as a system, apparatus, method, program, storage medium, or the like. Specifically, the present invention may be applied to a system composed of a plurality of devices, or may be applied to an apparatus composed of a single device.
