Copies

Copying machines have come a long way since the days of the hand-cranked methylated spirits duplicator:

Today’s copiers range from the highly versatile automatic offset printer that produces a quality printing job to the mobile, desk-side convenience copier using the new fibre optics (right).

In between are a range of compact, electronic copiers, smaller, cheaper and more versatile than ever. A much finer textured micro-carrier ha appeared with tiny particles that give a very precise image. Minolta has it, along with a flat, paper path that reduces the possibility of jamming and micro-con-p puter controls for a wide range of operations. The modern plain paper copies is more versatile and quiet than earlier models, servicing is simplified and machine size much reduced. So is electricity consumption. Comparatively cheap machines can now copy even blue with crispness and clarity, and the copy can be made darker or lighter at the touch of a switch.

Other good features to watch out for include selfmonitoring of both operations and fault correc-

tion, and a design that makes the inside easy to get at for servicing. On some models it is even possible to reproduce overhead projector film, and it is handy to be able to print onto a wide variety of paper sizes. For some situations, a reducer is also invaluable. Speed of delivery is often important, but quality can be more so. Generally, the fastest machines still fall down a little on quality, so it is helpful to make a fairly accurate assessment of the main use

to which the machine will he put before looking at current options. The assessment may be modified in the light of modern machine capabilities and prices, but with such a wide range of copiers now available it .is helpful to have a starting point. ■ Machines can be bought, leased, rented or hired. Whichever choice is made, back-up service is an important consideration, despite the improved reliability of microprocessor control. •
