The machine is necessarily quite elaborate and is not intended to compete with “small desk top copiers”, the Rank firm says. The plan is to rent the machines to users for £30 per week, as is already done for many of the more elaborate office machines today. If 100 copies are made per day, the cost per copy will work out at just under 4½d. If 250 copies are produced, this drops to 4d per copy.

The dedicated office efficiency expert may be dismayed at a machine that makes it still easier to circulate copies of documents all round an office. But where copying is essential, xerography offers one of the most up-to-date and convenient ways of doing it.
