FAX-L350 Chapter 1: General Description
1. FEATURES
1.1 Overview
This product is a G3 tranceiving facsimile based on the ITU-T recommendation. It can be used in telephone
networks.
High image quality
Ultra-high quality image processing. Gives faithful reproduction of documents.
Plain paper printing with LBP
The printer section uses an LBP which employs an on-demand fixing system, operating the fan and fixing
heater only when printing, and prints on plain paper.
Excellent print quality and speed
The FAX-L350 offers 600600 dpi laser beam printing, providing you with high resolution text and graph-
ics. The exceptional printing speed of 6 pages per minute allows you to work more effectively.
Toner detection function
This unit uses a magnetic (permeability) sensor to detect remaining toner.
Automatic dialing
There are 32 one-touch dial locations, and 100 coded-speed dial locations. Registered numbers can be
retrieved using the telephone directory feature.
Improved speed
This fax unit is equipped with the ITU-T standard V.34 mode which enables transmission speeds up to
33.600 bps ,more than double the rate of older G3 fax models.
Improved data compression
JBIG, a new data compression method, compresses data to approximately one-fifth the block size attained
with MMR data compression. The smaller block size requires less transmission time, and this means saving
you time and money.
Memory reception
No need to worry about toner or recording paper running out in the middle of a reception. Received docu-
ments are stored in memory until they can be output later.
Delayed transmission
Documents can be sent automatically, at a preset time. This means that documents can be sent late at night,
thus reducing transmission costs.
