Claim of US Patent No. 10,924,617

1. An image forming apparatus capable of communicating with portable terminals via a wireless network, comprising:a cassette that stores sheets;
an image forming device that forms an image on a sheet conveyed from the cassette;
a sensor that detects presence/absence of a sheet in the cassette;
a network interface for communicating with the portable terminals via the wireless network;
a memory for registering an address of at least one of the portable terminals as a target to which an error is notified; and
a controller for controlling the network interface, in a case where the address is registered in the memory, such that:
the network interface transmits error occurrence information indicating occurrence of a sheet shortage error for the cassette to the portable terminals in a case where absence of a sheet in the cassette is detected by the sensor;
the network interface transmits recovery operation start information indicating that a recovery operation for the sheet shortage error has been started to the portable terminals in response to detecting that the cassette has been opened; and
the network interface transmits error recovery information indicating that the error is recovered to the portable terminals in a case where presence of a sheet in the cassette has been detected by the sensor,
wherein, in a case where the address is not registered in the memory as the target to which the error is notified, the controller does not perform the transmission processing of the error occurrence information, the recovery operation start information, and the error recovery information.
