PRODUCT DESCRIPTION

CHAPTER

EPSON Stylus CX3700/CX3800/CX3805/CX3810/DX3800/DX3850 Revision A

1.1 Overview

This unit features 3-in-1 functionality (computer-connected printer, scanner, and standalone copy machine) and is designed for home/personal use. Its main functions are described below.

1.1.1 Features

 Printer functions

As a printer, this unit achieves high-quality output at high speed on plain paper, and uses new pigment ink for improved light fastness, water fastness, gas fastness, and rubbing fastness. It includes the following features.

 Maximum print resolution: 2880 (H) x 1440 (V) dpi

 Separate ink cartridge for each color

 ASF (Auto Sheet Feeder) holds up to 100 cut sheets (64 g/m

 Border-free printing with EPSON specialty media

 Reduced noise level

 Fast and thick draft mode with the combination of real black and composite

black

 Scanner functions

Use of a CIS sensor means no warm-up period is required, which makes scanning more convenient and allows for a more compact scanner. Additional features include the following.

)

 Enlarge / Reduce factor can be selected from two options; actual size (100%)

or “Fit to page”.

 Copy margin is automatically selected from three options, related to paper

type and paper size; 3mm, “Small Margins Copy”, or “Border Free Copy”.

 Fast and thick draft mode with the combination of real black and composite

black

 Scan functions

This unit provides scan mode so that data can be scanned and transferred to a connected computer or to e-mail via application software like EPSON SMART PANEL.

 Simultaneous use of functions

Printer functions and scanner functions are independent and can therefore be operated simultaneously from a connected computer.

 Easy operation panel

The unit has a simple operation panel equipped with seven buttons including power button and LEDs, and provides basic functions only for easy operation.

 Exterior design

Use of a CIS scanner engine has enabled a more compact design. Also, this unit has operation panel on the left side, which becomes more distinctive but still easier to use.

 Maximum optical resolution: 600 x 1200 dpi

 Scan gradations: 48 bits (input), 24 bits (output)

 Stand-alone copy functions

It benefits from using a more recently developed type of ink which enables photoquality copies to be made not only on special media but even on plain paper. Only the basic copy functions are provided for easier operation.

 Paper size can be selected from two options.
