PRODUCT DESCRIPTION

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/m2)

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.

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.

Table 1-1. Paper Size

Paper Size	Model
Letter/4"x6"	EAI
A4/10x15	Europe/Asia

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.

1.4.1.2 Zoom Function

The zoom function provides enlarged or reduced copies of originals. The either of the following can be selected from the operation panel.

Actual (The state which “Fit to page” is not selected. It is the power-on default.) The zoom factor is set to 100%.

Fit to page

This function detects the image size of the original and automatically sets the zoom factor of the copy according to the copy paper's printable area.

1.4.1.3 Maximum Copy Size

216 mm x 297 mm

1.4.1.4 Copy Layout

The following copy layout is provided according to “Paper type”, “Paper size” and zoom selections.

Standard copy

Provided for ordinary use with 3mm copy margin from every side.

BorderFree copy

Border-free printing of copies occurs when the print area is set as larger than the copy paper's size. In such cases, the outer edges of the original image may be omitted in the printed copy.

NOTE: Only “Standard Copy” can be used in draft copy mode.

Note *1: Actual is the state that “Fit to page” is not selected.

*2: “Fit to page” automatically sets the enlarge/reduce scale so that the entire image fits into the printable area or the border free area when border free layout is selected. When the original image is smaller than general card size (approx. 54mm x 86mm), the print margins will be different from the one that is defined by each layout.

The image placement uses the upper left corner as the origin and any margins that occur during the fitting process occur along the bottom and/or right edge.

When the original image is smaller than general card size (approx. 54mm x 86mm), the print margins will be different from the one that is defined by each layout.

The image placement uses the upper left corner as the origin and any margins that occur during the fitting process occur along the bottom and/or right edge.
