General Description

FAX-L260i Chapter 1: General Description

1. FEATURES

1.1 Overview

This product is a G4/G3 transceiving facsimile based on the ITU-T recommendation. It can be used in EuroISDN. *: This mark indicates new function

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

This product offers 600∞600 dpi laser beam printing, providing you with high resolution text and graphics. 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 16 one-touch dial locations, and 100 coded-speed dial locations. Registered numbers can be retrieved using the telephone directory feature.

ECM transmission

The ECM system provides communication error detection and retransmission of image data.

Memory reception

No need to worry about toner or recording paper running out in the middle of a reception. Received documents 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.

ON-HOOK Dial Function

Used in the event of facsimile information service. After dialing and connecting to the remote terminal, it is possible to send a DTMF signal and have manual communication.

Subaddress/Password Communications Function

Transmissions using “Subaddress” and “Password” which conform to the ITU-T standard can be used with this machine. Convenient uses can be found when used in combination with the other terminal’ s memory box function, etc. It can use both G4 and G3 communications.

1-1

FAX-L260i Chapter 1: General Description

Polling Receiving Function

Using this function, a document placed at the other party’s terminal may be taken out. This can also be used in combination with “Subaddress” and “Password” which conform to the ITU-T standard. It can use both G4 and G3 communications.
