  • Patent number: 10700631
    Abstract: While a stepping motor for conveying a paper is being driven, a first clocking section enables a counting control section to add a first predetermined value to a count value each time a first predetermined period of time elapses. When the count value reaches a first threshold value, a motor stop determination section stops the motor. A second clocking section enables the counting control section to subtract a second predetermined value from the count value each time a second predetermined period of time elapses when the motor is stopped. When the count value falls below a second threshold value smaller than the first threshold value, a motor drive resuming section resumes the operation of the motor. A third clocking section enables the counting control section to subtract a third predetermined value from the count value each time a third predetermined period of time elapses when the stepping motor is stopped in a state in which the count value is smaller than the first threshold value.

  • Patent number: 10698348
    Abstract: An image forming apparatus includes a heater and a controller. The heater includes a plurality of heater elements arranged in a main scanning direction to fix an image on a sheet passing a nip. The controller is configured to determine image-forming regions and non-image-forming regions among sheet regions of the sheet divided in the main scanning direction and a sub-scanning direction based on image data of the image. The controller is further configured to determine, as heating regions, the image-forming regions and a first part of the non-image-forming regions satisfying a predetermined condition, and determine, as non-heating regions, a second part of the non-image-forming regions not satisfying the predetermined condition. The controller is configured to energize one or more of the heater elements corresponding to the heating regions, selectively at timing when the heating regions pass the nip.
