Image forming device configured to cut sheet- type medium and form image on cut medium

An image forming device, comprising:

• a media container configured to accommodate a roll body formed by winding a sheet-type medium in a roll;
• an image forming engine configured to execute an image forming process of forming an image on the sheet-type medium;
• a media conveyor configured to convey the sheet-type medium along a conveyance path from the media container to the image forming engine, the media conveyor having a plurality of conveying rollers including a first conveying roller and a second conveying roller, the first conveying roller being arranged on an upstream side along the conveyance path with respect to the image forming engine, the second conveying roller being arranged on a downstream side along the conveyance path with respect to the image forming engine;
• a cutter configured to cut the sheet-type medium, the cutter being arranged on an upstream side along the conveyance path with respect to the second conveying roller;
• a controller,
• wherein the controller is configured to control the media conveyor in such a manner that the sheet-type medium cut by the cutter is conveyed and discharged toward outside of the image forming device after a power is on and before first execution of the image forming process;
• wherein the controller is further configured to perform:
• obtaining a status of an on-path sheet-type medium after the power is on and before the first execution of the image forming process, the on-path sheet-type medium being the sheet-type medium located on the conveyance path;
• and
• causing the media conveyor to discharge the on-path sheet-type medium toward outside of the image forming device according to the obtained status of the on-path sheet-type medium;
• wherein, in the obtaining, the controller obtains, as the status of the on-path sheet-type medium, whether the on-path sheet-type medium has been cut by the cutter, and
• wherein the controller is further configured to perform:
• when the on-path sheet-type medium has been cut by the cutter, not causing the cutter to cut the on-path sheet-type medium;
• and
• when the on-path sheet-type medium has not been cut by the cutter, causing the cutter to cut the on-path sheet-type medium.

• a controller,
• wherein the controller is configured to control the media conveyor in such a manner that the sheet-type medium cut by the cutter is conveyed and discharged toward outside of the image forming device after a power is on and before first execution of the image forming process;
• a media sensor configured to detect whether the on-path sheet-type medium exists in vicinity of each of at least one of the plurality of conveying rollers,
• wherein, in the obtaining, the controller is configured to obtain the information indicating the status whether the on-path sheet-type medium is located at a dischargeable position dischargeable by the plurality of conveying rollers based on detection result by the media sensor;
• wherein the media sensor is configured to detect whether the sheet-type medium exists in vicinity of a closest roller, the closest roller being a conveying roller, among the plurality of conveying rollers, located at a closest position to the image forming engine at a upstream side with respect to the image forming engine in the conveyance path, and
• wherein, in the obtaining, the controller is configured to obtain the information indicating the status whether the on-path sheet-type medium is located at the dischargeable position based on whether the sheet-type medium exists in vicinity of the closest roller;
• wherein, in a case where detection result of the media sensor at a time when the power is off and detection result of the media sensor at a time when the power is on from a state where the power is off coincide with each other, the controller is configured to obtain, in the obtaining, the information indicating the status whether the on-path sheet-type medium is located at the dischargeable position based on the detection result of the media sensor.
