1.INTRODUCTION
The two models referred to in this manual are desktop facsimile machines with a
bubbleinkjetprintingsystemwhichcomplies withtheITU-TSG3standardfordocument
transmission and reception.
The most suitable factor to distinguish between the two models, similar in appear-
ance, is the possibility of using a monochrome print head only or both monochrome and
colour print heads.
The colour model, once connected to a PC equipped with the LinkFax 8 software
communication module, can be transformed into a multifunctional product able to
perform both printer and scanner functions in addition to the facsimile traditional
features. The colour print head must be used only for printing purposes. All standard
facsimile functions require a monochrome print head. In this manual, the two models
are referred to as follows:
standard model (monochrome) LinkFax model (colour)
1.1MAIN FEATURES
•Bubbleinkjetprinting
The facsimile machine prints on plain paper (standard model) or special paper
(LinkFax model) in various formats (A4, Letter, Legal).
•Memorycapacity
The facsimile machine has a memory which enables operations such as One-
touch Dialling, Speed Code Dialling, Broadcasting Transmission, Delayed Trans-
mission and Substitute Reception, as well as the storage of parameters, data and
documents. This memory is powered by a backup battery in the event of a power
failure.
•Halftones
In the scanning of documents, a scale of 64 half tones can be used for a higher

quality reproduction of photographs and pictures.
•Automaticdocumentfeeder(ADF)
This device enables up to 10 sheets of A4, A5, Letter US or Legal paper, with a
maximum thickness of 0.1 mm/sheet, to be fed in automatically.
•Telephoneansweringdevice(TAD)
The model without a built-an TAD can be connected to an external one.
