The HP Fax 640 was made for homes or small offices that only fax occasionally. Only 6.6 pounds, it offers fast faxing and copying, as well as a 10-page automatic document feeder.
Only one color of Fax 640 ink is needed inside the unit, and each tank will last about 350 pages before expiring. Resolutions of 600x300 dpi are available when copying, and resolutions as high as 300x300 dpi are possible when faxing.
One downfall with this machine is its speed. When copying, only up to 4 pages per minute can be created, and faxes only get sent at 14.4 Kbps. The copy machine, though small, does still have the ability to reduce and enlarge documents from 50%-150%. The copier can also create up to 50 copies from every original document, which is impressive. The fax machine has a memory capacity of 50 pages, and up 50 stations can be logged into the speed dial.
