I'm not sure whether this applies to all digital photocopiers, as I expect you can get some simple ones that act more like the so called 'analogue' photocopiers, but some digital photocopiers do do some really good stuff.
We have some Gestetner photocopiers in the libraries at college. They will photocopy stuff, at a cost - 5p A4 B&W, 10p A3 B&W, 50p A4 Colour, £1.00 A£ Colour. They will print stuff from the computers in the library, but as they are on the college network, you can print to them from anywhere. It will do black and white for free, and will also duplex it automatically. For colour you are supposed to get your teacher to fill in a permission form, and then they will allow it, but sometimes they didn't block the colour printer driver and you can print loads of colour stuff anyway .
They can also scan stuff upto A3 and in colour. It will either do it as TIFF or PDF, and you can set it to make a multi page PDF file and it will email it to your college email account, so you can log on to the computer and print it to avoid photocopying charges .
I was wondering if anyone else had used such a device? I have found it really good for scanning stuff. It is extremely quick. It can just be a little awkward to set it up using the touch screen, but that isn't really a problem.
Also, what are modern flatbed scanners like at scanning in terms of speed? Mine was made in 2001 and is a little slow.
