A quick introduction to fax
What's a fax document?
A fax document is anything a fax user wants to fax to someone else. It can be one or
more pages, and it can be text, a drawing or even a copy of a photograph.
What's a fax number?
Because your fax operates on standard phone lines, a fax number is just a regular
phone number. And because your fax is also a high-quality, full-featured telephone,
your fax number can be your regular phone number.
What are resolution and grayscale?
Just as cars are measured by engine size, fax machines are measured by resolution
and grayscale.
Resolution refers to the sharpness of a fax transmission. It's expressed in lines per
inch (lpi). There are at least three levels of resolution for most fax machines:
• Normal (203 horizontal 98 vertical lpi)
• Fine (203 196 lpi)
• Superfine (406 392 lpi).
Grayscale levels, or shades of gray — refers to the many shades of gray your fax
machine sees on a document it's sending. It's likely most of your fax documents will
be dark text on white paper. However, when you want to send photographs and
other shaded items, you can send your fax documents with 256-level grayscale.
Why not always set your fax machine for superfine,
or for grayscale?
Setting your fax machine for superfine resolution and grayscale mode makes your
machine send more information, making transmissions last longer and potentially
driving up your phone bills on long-distance calls. You'll find that we've made it
easy for you to set your fax machine for the most efficient and truest transmission
for the types of documents you send.
