I wish to buy a multi-function device that meets the following criteria:
1 Copy speed between 45 - 90 pages per minute
2 Integrated network scanner which creates .pdf files from scanned images
3 Option to prescribe specific email destination for a scanned item,
or call an address from an address book
4 Integrated fax
5 Duplex copying and scanning
6 Black & White only
7 Network printer
8 Maintenance costs for support and consumables of approximately .25
cents (US) .5 pence (sterling) per copy

I have a Konica Minolta 7145 which meets all these requirements, but I
want a machine that handles these tasks faster. Konica's faster
machines are primarily printer/scanners with no fax option
