: The official utility used by technicians to communicate with the device firmware.
The Canon iR2016 is a 2005-era device. While rugged, finding parts and parallel-port computers is difficult. If the DC controller board is dead, replacement cost ($100-$200 used) may exceed the value of the device. Consider upgrading to a modern Canon imageRUNNER (e.g., 1643i or 2204) if you cannot resolve the error.
