MultiPASS C755 Chapter 1: General Description

1. FEATURES

1.1 Overview

This product is a G3 transreceiving facsimile based on the ITU-T recommendations. It can be used in

telephone networks.

*: This mark indicates a new function.

Picture Quality Color Printer

High quality printing can be accomplished with the Canon Bubble Jet (BJ) method using the maximum

1440dpi ×720dpi resolution. Various kinds of media can be printed with the high speed of a maximum

8.7 pages per minute. The printing paper tray can hold up to 100 sheets of plain paper, 50 sheets of OHP

film, or 10 back print films or envelopes.

*Plain paper fax which can transmit/receive in color

Conforming to ITU-T recommendations, this fax is able to transmit/receive in color. Due to containing

extremely high-speed 33.6kbps modems, transmission time can be shortened. Pictures and photographs

can both be send and received clearly by UHQ(Ultra High quality), Canon’s vivid image processing

technology. Up to 20 letter- or A4- size sheets, or up to 10 legal-size sheets, can be set in the ADF. 12

one-touch dial entries and 100 speed dial entries can be registered, and group dial and broadcasting

transmission can also be done. When paper and ink run out, the data is saved to memory, so there is no

worry. When a external-phone is attached, fax communication and normal telephone reception are

possible due to DRPD service and FAX/TEL switching.

BJ Cartridge

Printing quality superior to photos is produced by use of BC-30 and BC-33/BC-34 photo BJ cartridges.

*Out-of-Ink Function

This machine has a function which detects when ink has run out. It also detects when the cartridges of

machines equipped with color communications are out of ink. The presence/absence of ink in the ink

chamber is detected by reflecting ink sensor.

Copy Function

This machine can be used as a 360dpi ×360 dpi high resolution full color copier. With a monochrome

document (including half-tone), up to 99 pages can be copied at one time at the speed of a maximum of 3

pages/minute.

Full Color & 256 Gradation Grayscale Scanner

Using graphics or OCR software which conforms to the TWAIN standard, full color and 256-gradation

grayscale images with a quality of 30dpi ~ 600 dpi can be read into a computer. Reading in can be done at

a resolution of 300dpi, and can be enhanced to 600dpi using the included MultiPASS Suite.

PC Fax

By connecting this machine to a computer, a fax can be transmitted from the included MultiPASS Suite

or from a Windows application, and a received image can be saved to the computer as-is without printing

it out.
