Xerox 720

Xerox 720

The Xerox 720 was another version of the 914 copier, and the only difference was...

The 720 Copier / Duplicator, as it was styled, was a double speed version of the Xerox 420. By the re-gearing of a more powerful main motor, throughput was doubled from 7 copies per minute to 14 copies per minute. Output speed was only maximised to 17 cpm. with a later field modification, known as the Short Scan mod.

The 720 came with Differential Billing as standard, complete with the steel tube, platen cover handle, a flush front door, a new two tone grey paint job and a 'Collator Unit' which was a set of 10 shelves designed, in the main to make the machine look different.

Short scan was achieved by initiating optical 'Flyback' at the normal A4 length, thus saving about 2 inches per scan and speeding up the machine to, a theoretical, 17cpm. It was rarely, if ever, used.

However, speeding up the machine was not simply a matter of gearing.
A faster, and less robust, drum coating needed to be used, along with brighter lamps and increased corotron currents. An uprated developer also had to be formulated and a bigger, hotter fuser unit fitted. Then, the drum cleaning unit had to be uprated and a larger capacity filter bag fitted.

The 720 and 660 were the first machines I was trained on at RX Newport Pagnell back in 1973. I remember that the original 914’s were supplied with a fire extinguisher clipped to the outside as a “fuser fire” was not unusual. Some of the more challenging jobs were replacing the scan cables and also changing the clutch that was buried in the depths of the thing. I forget its name but it was very difficult to keep all the toothed belts in place when working on it. Fault finding was invariably done with the power on and it was… Read more »
