About This Guide

This user’s guide provides fully-illustrated, step-by-step

instructions for setting up and operating the SQ-850 and

SQ-2550 printers.

Finding your way around

Chapter 1 contains information on unpacking, setting up,

testing and connecting the printer, so be sure to read and

follow the instructions in this chapter first.

Chapters 2 and 3 include important information on paper

handling and general printer operation. This information is

necessary for the day-to-day operation of your printer.

Chapter 4 contains information designed to help you get the

most from your printer. This chapter includes advice on the

use of software commands, graphics, and user-defined

characters. Also, see Chapter 9 for a summary of printer

commands.

If the printer does not operate properly or the printed

results are not what you expect, see Chapter 7 for a list of

possible solutions.

Other chapters contain information on general maintenance,

use of the printer options, and specifications. You will also

find a glossary of printer terms and an index.

At the back of this guide is a Quick Reference Card with the

information you are most likely to need.

Note: The SQ-850 and SQ-2550 are basically the same printer

except that the SQ-2550 can accept wider paper. Therefore,

the illustrations in this guide show only the SQ-2550.

2 About This Guide

Introduction

The SQ-850 and SQ-2550 are the latest in EPSON’s advanced

line of 24-nozzle ink jet printers, combining high performance

and reliability with a wide range of exciting features.

Features

In addition to the high-quality printing and ease of operation

you have come to expect from EPSON printers, the SQ-850 and

SQ-2550 offer the following:

An improved control panel design that allows you direct

selection of all of the printer’s main features, such as

character font and pitch as well as a choice of normal or

condensed printing.

An advanced paper handling system that allows you to

easily switch between single sheets and continuous paper by

pressing the appropriate panel buttons. You can use single

sheets without removing the continuous paper, or you can

use continuous paper even while the optional Cut Sheet

Feeder is installed.

A short tear-off feature that saves paper. After you tear off

the latest sheet printed on continuous paper, the printer

feeds the paper back to the loading position so that you can

use all of the next sheet.

The ability to print on labels and envelopes.

A micro-adjustment feature that allows you to feed the

paper forward or backward in 1/180th of an inch

increments to finely adjust the top of form, loading, and

short tear-off positions.
