Scan Settings
You may want to send many different
types of fax messages. Some of these
may be difficult to reproduce at the
other end. However, your machine
has two settings that you can adjust to
help you transmit your fax message
with the best possible image quality.
❖
Resolution:
Standard , Detail , Super Fine , Ex-
tra Super Fine
❖
Original Type:
Halftone
,
Color Scan
(Optional)
Note
❒
You can set whether the machine
returns to the same settings after
the power is turned on with the
User Parameters (switch 01, bit 7).
See p.140 “User Parameters”,
Ad-
vanced Features .
Resolution
Images and text are scanned into the
machine by converting them to a se-
quence of dots. The frequency of dots
determines the quality of the image
and how long it takes to transmit.
Therefore, images scanned at high
resolution (
Super Fine ) have high
quality but transmission takes longer.
Conversely, low resolution (
Stand-
ard ) scanning results in less quality
but faster transmission. Choose the
setting that matches your needs
based upon this trade off between
speed and image clarity.
