Abstract: An example image forming apparatus includes a detection device to detect loading of paper output from the image forming apparatus, a user interface device, a processor, and a memory to store instructions executable by the processor. The processor is to, by executing the instructions, detect a folded state or an unfolded state of the detection device, display state information indicating a state of the detection device on the user interface device, and control an operation of an image forming job based on the state information of the detection device and mounting information of an output option device.

Abstract: A sensor cleaning device to clean a sensor to detect a printable medium on a transferring path. The sensor cleaning device includes a cleaning lever, and a driver. The cleaning lever is coupled to a cleaner at an end of the cleaning lever. The driver is coupled to the cleaning lever and is to drive the cleaning lever to move the cleaner from a first position to a second position and back to the first position, the first position being away from the transferring path and the second position being in contact with the sensor.
