  • Patent number: 10919314
    Abstract: A print medium is conveyed in a first direction and a printing head prints an image on the print medium by using a printable region of the print head that extends in a second direction crossing the first direction. Storing units can feed multiple sorts of print media. Among the multiple sorts of the print media, the print medium to print a check pattern for checking a printing state of the printing head is selected as the print medium to be fed from the corresponding storing unit. The check pattern is printed on the print medium by using a portion of the printable region of the printing head corresponding to a size of the print medium fed from the storing unit.

  • Patent number: 10857799
    Abstract: An image forming apparatus includes a housing, a movable body, a rack, a gear, a stepping motor, and a first action body. The movable body moves between a first position and a second position with respect to the housing. The first action body acts on the movable body. When an output shaft of the stepping motor rotates in a first rotation direction, the gear rotates to move the movable body in a first direction from the second position toward the first position. The first action body applies a pressing force toward a second direction opposite to the first direction to the movable body moving in the first direction beyond the first position. The pressing force is smaller than a force enough to rotate the output shaft of the stepping motor by one step in a second rotation direction opposite to the first rotation direction.
