Xerox also produced another version of the 3100 model, and the copier was named Xerox 3100 Diplomat. See image of the copier to the right.

This was a refurbished 3100 with the cupboard removed from the device and replaced with a single, sturdy pole supporting the machine but retaining the same wheels. Also the orange was sprayed brown so that the device had a 1970s brown and beige colour scheme.
