Xerox 3100LDC/3103

The Xerox 3100 LDC and 3103 were one and the same machine, in different markets. Marketed by Rank Xerox as the 3103, it was a re-engineered 3100, with a flip-up platen cover and a document feeder that moves the document over on to the glass, when you pull the lever forward. This was the analogue precurser of all todays digital, slit-glass scanners.

It also had adjustable developer bias, to give additional 'Light Original' and 'Coloured Background' settings. These levels could be adjusted, by an engineer, to the customer's requirements. In practice, this feature was rarely used. It was intended to reduce copy quality complaints but, sadly, did not.
