Abstract: A first cover moves between a first closed position and a first open position. The first cover is located at another end of a housing when the first cover is located at the first closed position. A second cover moves between a second closed position and a second open position. The second cover is located closer to one end than the first cover is at the first closed position and at the second closed position. A first portion of a first conveyance path is formed between the first cover and the second cover at the first closed position and at the second closed position. A second portion of a second conveyance path is formed at a side of the second cover facing the one end at the second closed position. When the first cover opens the first portion, the second cover is located at the second closed position.

Abstract: A first conveyance path and a second conveyance path are formed in a housing. The first conveyance path extends in a conveyance direction to reach a first discharge port for discharging a sheet. The second conveyance path extends in the conveyance direction at a position higher than the first conveyance path to reach a second discharge port for discharging a sheet. The second discharge port is located at a position upstream of the first discharge port in the conveyance direction. A first print engine is provided at the first conveyance path. The first print engine is configured to print an image by using a recording agent on a sheet conveyed along the first conveyance path. A second print engine is provided at the second conveyance path. The second print engine is configured to print an image by using a recording agent on a sheet conveyed along the second conveyance path.

Abstract: An image forming apparatus includes a conveyor to convey a sheet medium, a print engine to form an image on the sheet medium, a cutter to cut the sheet medium, a signal output device, and a controller. The cutter includes a first blade, a second blade, and a moving device to move at least one of the first and second blades. The controller receives, from the signal output device, a signal indicating a variation over time in a value correlated with a moving load for the at least one blade, and determines, based on the received signal, which state the sheet medium is in among a plurality of states including a first state where the sheet medium is cut normally, a second state where there is an abnormality in cutting the sheet medium, and a third state where there is a different abnormality in cutting the sheet medium.

Abstract: A first cover moves between a first closed position and a first open position. The first cover is located at another end of a housing when the first cover is located at the first closed position. A second cover moves between a second closed position and a second open position. The second cover is located closer to one end than the first cover is at the first closed position and at the second closed position. A first portion of a first conveyance path is formed between the first cover and the second cover at the first closed position and at the second closed position. A second portion of a second conveyance path is formed at a side of the second cover facing the one end at the second closed position. When the first cover opens the first portion, the second cover is located at the second closed position.
