At this amount of printing (100,000 per month) you should probably look
at Canon's CLC and IRC ranges eg: CLC3220 iRC3220N both of these are
multi-function so can be photocopiers as well as printers. They, like
(I think) the Xerox 7750 are contone rather than halftone printers, so
for each of the colours can be varied in intensity over 256 steps giving
a much wider gamut, whereas the lower range lasers (and inkjets) don't
have this facility and either there is a coloured dot or there isn't so
they use the dithering to try and generate all the different colours
required. I _think_ that both the above printers are single pass, so
when it prints a colour page it lays down all four colours at the same
time, whereas lower grade (and older) printers tended to be four pass -
the paper would go through four times for a colour page, eg ,my machine
CLC950 is something like 7 ppm colour but 28 ppm black only.
Another alternative supplier could be Ricoh with something like their
Aficio CL7100 which is a printer only or Aficio 2232C which is a
photocopier as well.
If you don't need the colour you can obviously get black only version of
similar printers for considerably less money! At the level you are
looking at I suppose you should probably look at cost per copy
maintenance agreements and possibly leasing - depending what the
accountant says. After all a penny a page at 100,000 pages a month soon
adds up. And you can expect to need someone to come along and fiddle
with it fairly regularly.
