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.
