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 600´600 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.
