From memory, the official method is to hold down the stop button while powering on the machine to clear this error.

However, when i see it, I also ensure the contacts are clean on both the "T/C" and the machine, and just at the point the cartridge lowers when closing the door, i stop closing the door and push the "T/C" downwards good and proper manually and then close the door.

Also make sure at idle the memory is at 100% anything less after a fresh power on and there are no faxes stored in memory means the memory contains corrupt fax data and a DRAM clear is required. (more prevalent on the F2900/3900, but also occurs on these and everything up to the B163 series) Strange behavior results from this alone.

Its this terminal getting dirty inside and/or having warped contacts. Just solder a resistor as shown in the picture and machine believes that a unit is present.
