FX - 850/1050 DOT - MATRIX PRINTER DIP Switch Functions
The tables below describe the DIP switch functions. The page numbers refer you to the page on which each printer feature is described. The shaded settings are the preset factory settings. DIP Switch I Cut sheet feeder mode When DIP switch 2-2 is on, you can use your printers optional cut sheet feeder. See Chapter 7 for more information on using a cut sheet feeder with your printer. Skip over perforation When DIP switch 2-3 is on, a one-inch margin is provided between the last line printed on one page and the first line printed on the next page. When using continuous paper, this feature causes the printer to stop printing, skip over the perforation, and then resume printing. If you adjust your loading position correctly, you can get half of the margin at the bottom of one page and half at the top of the next page. See the section on adjusting the loading position later in this chapter.
Note: Most application programs take care of the top and bottom margins. Only use skip over perforation if your program does not provide these margins

Automatic line feed When DIP switch 2-4 is on. a carriage return code (CR! causes an automatic line feed. When it is off, line feeds occur only when the printer receives line feed codes (LF). Since some computers and application programs automatically add line feeds to carriage returns, the setting you use depends on your computer and application program. Default character set When DIP switch 1-1 is on, the user-defined character set is the default. User-defined characters are maintained in printer memory even when the power is turned off, so the user-defined character set can be selected simply by setting this switch to on. However, when this switch is on, new user-defined characters cannot be defined. See Chapter 4 for more information on user-defined characters. This switch is effective only in the Epson ESC/P mode. Zero character When DIP switch 1-2 is on, the printer prints slashed zeroes (0). When the DIP switch is off, the printer prints open zeroes (0). This is useful for clearly distinguishing between uppercase O and zero when printing such items as program lists. Character table

International Character Sets
Selecting an international character set provides you with the characters used in other languages. To obtain the desired international character set, set switches 1-6, 1-7, and 1-8 according to the DIP switch table on page 3-7. The following table shows the characters that differ in each international character set.

I Installation/Support

Software

The type of printer installed on your system must be identified for each software package. This is usually done through a setup menu. If this printer is not listed in your program, look in the printer Users Manual for the next-best model selection.

DIP Switch Settings

The default settings will usually work for most applications, but they should be checked before using the printer This will avoid unexpected results.

Serial Operation

The FX-850/1050 will be able to receive serial data with the addition of an Epson 81XX series interface option.
Cut - Sheet Feeder Operation
The page length will have to be adjusted (shortened) to 61 lines per page if your software does not properly support cut -sheet paper. There will be lines from the first page printed at the top of the second page if the page length is not set correctly.

Disabling the Buffer

An undocumented feature of the FX-850/1050 is the ability to disable the buffer from the SelecType panel. To toggle the buffer hold down the Load/Eject switch at power on. Two beeps indicate that the 8K buffer is enabled, and one beep indicates that the buffer is disabled. (Some spooler applications wont work correctly unless the buffer is disabled.)

Introduction

The FX-850 and FX-1050 printers combine all the well-known features of previous Epson 9-pin printers with many features normally exclusive to costly 24-pin printers.

Features

In addition to the high-quality printing and ease of operation youve come to expect from Epson printers, the FX-850 and FX-1050 offer the following: The SmartPark paper handling system that lets you use single sheets of paper without removing the continuous paper, eliminates paper waste with short tear-off, and allows easy and accurate paper alignment. An improved control panel design that allows direct selection of character fonts and pitch, as well as a choice of draft or near letter quality (NLQ) printing. High-speed draft mode with fast printing of up to 290 characters per second at 10 cpi. The ability to handle a wide range of paper types, including envelopes. Double-high and double-wide printing for headings and special emphasis. An IBM printer emulation mode that provides compatibility with application programs written specifically for IBM printers.

Options

A variety of printer options are available for use with FX printers. For detailed information on the installation and use of these options, see Chapter 7.
Single-bin and dual-bin cut sheet feeders
A cut sheet feeder gives you easier and more efficient handling of single sheet paper. Up to 150 sheets of standard bond paper can be fed automatically into the printer without reloading. This unit also can automatically feed envelopes.

Pull tractor unit

This option improves the performance of continuous paper handling. It is especially useful with continuous multi-part forms.
Optional interface boards
A number of optional interfaces can be used to supplement the FXs built-in parallel interface. Guidelines for choosing the right interface and instructions on installing the boards are given in the section on interface boards in Chapter 7.

About This Manual

This users manual provides fully illustrated, step-by-step instructions for setting up and operating the FX-850 and FX-1050 printers. The FX-850 and FX-1050 are basically the same printer except that the FX-1050 can accept wider paper. The illustrations in this manual usually show the FX-1050 printer.

Finding your way around

Chapter 1 contains information on unpacking, setting up, testing, and connecting the printer. 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-today operation of your printer.

4. Slide the print head to the middle of the printer. Then, use the enclosed cross-head screwdriver to unscrew and remove the two red screws.
WARNING: Be sure to remove all protective materials before you turn on the printer.
Choosing a Place for the Printer
When you select a location for your printer, keep the following in mind:
Place the printer on a flat, stable surface. Place the printer close enough to the computer for its cable to reach. Leave adequate room around the printer to allow for easy operation and maintenance. Use a grounded outlet; do not use an adapter plug.
The illustration below shows a good printer setup.
Caution: If you put the printer on a stand, be sure that the stand
does not tilt the printer more than 15 degrees.

WARNING:

Avoid locations that are subject to direct sunlight, excessive heat, moisture, or dust. Avoid using electrical outlets that are controlled by wall switches or automatic timers. Accidental disruption of power can wipe out information in both your computers memory and your printers memory. Avoid using outlets on the same circuit with large motors or other appliances that might disturb the power supply. Keep the entire computer system away from potential sources of interference such as loudspeakers or the base units of cordless telephones.

Assembling the Printer

To assemble the printer, you need only do the following:
Install the platen knob Install the ribbon cartridge Attach the paper guide.
Installing the platen knob
The first step in setting up the printer is to install the platen knob. You should never need to use this knob during the normal operation of your printer. However, in case of a paper jam, you can use this knob to manually feed paper. (Be sure the printer is turned off before using the platen knob.) Youll find the platen knob packed in an indentation in the white foam packing material.
1. Insert the knob into the hole on the printers side and rotate it until it slips onto the shaft.
2. Push firmly on the knob until it fits against the printer case.
Caution: Never use the platen knob to adjust the position of the paper except in the case of a paper jam. Only use the platen knob when the printer is turned off.
Installing the ribbon cartridge
Follow these steps to install the ribbon cartridge: 1. Slide the print head to the middle of the printer.
Caution: Never move the print head while the printer is turned on because this can damage the printer. Also, if you have been using the printer, the print head may be hot; let it cool for a few minutes before touching it.

Using Single Sheets

Your printer can handle a wide range of paper sizes up to a maximum width of 10.1 inches on the FX-850 or 14.4 inches on the FX-1050. Always make sure that your printing is confined to the size of paper you are using. Never print on the platen (black roller). If you do most of your printing on single sheets, you may find it more convenient to install the optional cut sheet feeder. This option automatically inserts a new sheet whenever required and can hold up to 150 pages or 25 envelopes. For more details, see Chapter 7. To load a single sheet of paper follow these steps: Note: If you already have continuous paper loaded, follow the instructions on page 2-10 for switching between continuous paper and single sheets. 1. Turn on the printer. 2. Push the paper release lever back to the single sheet position.
Stand the paper guide in an upright position and align the left edge guide with the arrow on the paper guide. (You may want to change this position later, depending on the margin settings of your application program.)
4. Adjust the right edge guide to fit the size of the paper. 5. Slide the paper down between the edge guides until it meets resistance. At this point, the PAPER OUT light turns off.
6. Press the LOAD/EJECT button to automatically feed the paper to the loading position. WARNING: Never advance the paper using the platen knob while the printer is turned on. 7. Press the ON LINE button so that the ON LINE indicator lights up.
If the platen (black roller) turns but the sheet does not load, remove the sheet completely from the printer. Then make sure the paper release lever is pushed back. Press the paper a bit more firmly into place and try again. To eject the paper, press the ON LINE button to take the printer off line, and press the LOAD/EJECT button.
Reloading during printing
When you print a document more than one page long using single sheet paper, the printer stops printing when it reaches the bottom of the paper and ejects the page.! When this happens, either the ON LINE light goes off automatically or it may remain on, depending on your application software. If the ON LINE light remains on, the first thing you should do is press the ON LINE button to take the printer off line. Once the ON LINE light is off, remove the sheet that has just been printed and load a new sheet as before. Press ON LINE to start printing the next page.

BIN 1/BIN 2

On line: press this button to change between bin 1 and bin 2 on the optional dual-bin cut sheet feeder. The beeper sounds once if bin 1 is selected, or twice if bin 2 is selected.

SelecType

The settings you select using the SelecType panel remain valid even after you turn off, reset, or initialize the printer.
Press this button to select draft, near letter quality Roman, or near letter quality Sans Serif. The indicator light shows which font has been selected.

CHARACTERS PER INCH

Press this button to select the characters per inch (cpi). You can choose 10 CPI , 12 CPI, or PS (proportional). The indicator light shows the selected character spacing.

CONDENSED

Press this button to select either condensed or normal printing. The light is on when the printer is in condensed mode. In this mode, all characters are approximately 60% of their normal width.
Note: Proportional spacing and condensed mode cannot be combined. If you select both, only proportional spacing works.
Other control panel features
The control panel also gives you access to several special functions. Self test By holding down the FORM FEED or LINE FEED button while you turn on the printer, you can start the printers self test. This prints out the DIP switch settings and the characters in the printers ROM (Read Only Memory). See the section on the self test in Chapter 1 for more information.

Microadjustment

By pressing the FORM FEED and LINE FEED buttons immediately after loading paper or using short tearoff, you can make fine adjustments to the loading and short tear-off positions. See the section on microadjustment in Chapter 2 for more information. By holding down both the FORM FEED and LINE FEED buttons while you turn on the printer, you can turn on the data dump mode. This feature allows advanced users to diagnose many problems. See the section on the data dump mode in Chapter 6 for more information. The input buffer can be enabled or disabled by turning on the power while pressing the LOAD/EJECT button. The beeper sounds once if the input buffer is disabled, or twice if it is enabled. Use the self test to check the input buffers current state. The printer can be set to either high-speed draft mode or normal draft mode. Turn on the power while pressing the FONT button. The beeper sounds once if normal draft mode is selected, or twice for high-speed draft mode.

Setting the DIP Switches
By changing the settings of the two sets of DIP switches behind and below the platen knob, you can control various printer features, such as the character set and page length. These new settings become valid whenever the printer is turned on, reset, or initialized. Before you set the DIP switches, turn off the printer. Then use a pointed instrument, such as the tip of a pen, to move the switch to either the on or off position. The new settings become valid when you turn on the printer.

Using printer selection menus
If your software has a printer selection menu, simply choose FX-850 or FX-1050. If the menu does not list either of these printers, choose one of the following. They are listed in order of preference. FX-850 FX-86e EX-800 FX-85 FX-80 + FX-80 FX LX MX Epson printer Draft printer FX-1050 FX-286e EX-1000 FX-286 FX-185 FX-100 + FX-100 FX LX MX Epson printer Draft printer
If you plan to use the IBM emulation mode, choose IBM Proprinter (if you have an FX-850), IBM Proprinter XL (if you have an FX-1050), IBM Graphics printer, or IBM printer, in that order of preference. Note: If your application program does not list the FX-850 or FX-1050, you may want to contact the software manufacturer to see if an update is available.

A quick test

After setting up your application program, print a sample document to make sure the program and the FX are communicating properly. If the document doesnt print correctly, recheck the programs printer selection and installation procedure. If youre still having trouble printing, consult the troubleshooting section in Chapter 6.

Using word processors

Word processors usually let you use a fixed set of printer features by placing markers around the text to be altered. When the document is printed, the markers are recognized and translated into suitable commands for your printer. On your screen some programs show the markers; others display the text as it will appear-for example, in bold or italics. This method is normally restricted to features that can be found on almost all printers, such as bold and underlining. Some word processing programs also let you insert printer commands in your text. These commands may or may not be visible on your screen. This method has the advantage of allowing you to use any printer command, not just a limited set. To make use of it, however, you need to understand how to use your printers commands. Check the manual for your word processor to see if you can place printer commands in your text, and then see the section in this chapter on computer-printer communications.

Using spreadsheets

Although spreadsheets seldom use as many printing styles as word processors, they do have some very specific requirements. If your spreadsheet program provides a list of printers, use the list on page 4-2 to find the proper selection. If your spreadsheet doesnt have a printer setup routine, read the programs manual carefully for information on printing. A major concern for printing spreadsheets is the width of the printer. The FX-850 is an SO-column printer, and the FX-1050 is a 136-column printer. You can, however, increase the number of characters on a line by selecting 12 cpi, condensed mode, or both from the SelecType control

Using Software and -Graphics
your printer and other peripherals. These ASCII characters do not usually have corresponding keys on the keyboard and cannot be printed as characters by your printer.

Escape sequences

Although there are more than 30 control codes available to control the operation of your printer, many more codes are required to run todays sophisticated printers. Therefore, ASCII codes are grouped in sequences to represent certain functions. These code sequences use the ASCII codes with decimal values of 32 through 255, normally reserved for characters and punctuation, to control printer functions. This is done by first sending a standard code to tell the printer that the codes that follow are to be used as control codes, not as characters or punctuation. The standard code that is sent at the beginning of one of these code sequences is the Escape code, decimal value 27. Any sequence of codes starting with the Escape code is called an Escape sequence. You will probably see Escape written in different ways-such as ESC, Esc, and Escape-in various manuals. In this manual it is in the form of ESC when used within a command.

Printer commands

In order for the printer to recognize the instructions it receives, ASCII codes must be sent in a specific format, called a command. An Escape sequence is a command, as is any ASCII code or sequence of codes that instructs the printerto carry out a particular function. Your software continually sends commands to your printer and your computer screen. These commands instruct the printer to perform such actions as print in a particular typeface, feed the paper a certain amount after printing each line, and start printing on a particular spot on the page. Some software programs let you send these commands yourself. This is a powerful feature because it allows you to enhance your text in ways that may not normally be available through the software. For example, many word processing programs do not offer italics. By inserting a command in your document, however, you can use italics anywhere you like. The
commands that your printer recognizes are listed in the Command Summary in Chapter 8 and on the Quick Reference card at the back of this manual.
Using the Command Summary
The commands listed in the Command Summary in Chapter 8 consist of various combinations of ASCII codes. You can use either the ASCII characters or their decimal or hexadecimal equivalents. For example, the command to turn on subscript is ESC S1 in ASCII characters. The decimal format for this command is 01, and the hexadecimal format is 1B 53 01. In the Command Summary, commands are grouped by the printer functions they control, such as character pitch, print enhancement, and graphics. You can also look up commands in the list of software commands in numerical order at the beginning of the Command Summary. This list gives you page number references for the commands. Some commands include a variable, such as the letter n. For example, the command for selecting or cancelling double-high mode is ESC w n. When n = 1, double-high mode is turned on, and when n = 0, it is turned off. In the Command Summary, variables are printed in italics to distinguish them from ASCII characters.

Single sheets do not feed properly
The position of the paper release lever may be wrong. Push it back to the single sheet position. The paper may be too large or too small. See the paper specifications in Appendix A. The paper guide may not be installed properly. See the section on installing the paper guide in Chapter 1 and on using single sheets in Chapter 2. The cut sheet feeder mode may be selected by the DIP switch. See the section on setting DIP switches in Chapter 3.
Continuous paper does not feed properly
The position of the paper release lever may be wrong. Pull it forward to the continuous paper position. The paper may not be mounted on the sprockets correctly. See that the sprocket holes of the paper fit correctly over the sprockets. The paper guide may not be installed properly. See the section on continuous paper in Chapter 2. The paper supply may be stacked too far from the printer or not aligned with the tractor. Also, there may be some obstacle in the way of the paper or something on top of the paper supply. See Chapter 2 for instructions on the proper placement of the paper supply.
Cut sheet feeder does not load paper correctly
The cut sheet feeder mode may not have been selected with the DIP switch. The position of the paper release lever may be wrong. Push the paper release lever back to the single sheet position. The cut sheet feeder may not be installed properly. The paper supply may not be loaded properly. The paper may not be the type required for proper operation of the cut sheet feeder. The paper set lever of the cut sheet feeder may not be pushed back. The paper length may not be set correctly More than 150 sheets may be loaded. Remove the extra sheets.
See the section on the cut sheet feeder in Chapter 7 for more information on cut sheet feeder problems.

Data Dump Mode

The printer has a special feature to make it easy for experienced users to find the cause of communication problems between the printer and application programs. In data dump mode, an exact printout of the codes reaching the printer is produced. 1. To enter the data dump mode, hold down the FORM FEED and LINE FEED buttons at the same time while you turn on the printer. 2. Next, run either an application program or one you have written in any programming language. Your printer prints all the codes sent to the printer in hexadecimal format as shown below:
I 6 C 5 6D 0A 6 F 12 1B 0 0. @. R. t. 6. P. p. T h i s i s a n e x a mple of a d a t a d ump p r i n t o u t. Th i s f e a t u r e makes it easy fo 61 6E 6D 2E 6 F

5. Push the paper set lever back to clamp the paper against the guide rollers. The lever will not close completely if you use too much paper. If the lever does not close, remove some paper from the stack and try again.

Envelope loading

Envelopes are loaded in much the same way as regular paper. To load envelopes, you need to do the following: 1. Set the paper thickness lever to match the thickness of your envelopes. (For specific information on paper thickness settings, see the section on printing with special paper in Chapter 2.)
2. Follow steps 1 through 5 of the previous section on paper loading to load envelopes. You can load up to 25 plain or bond envelopes, or 30 air mail envelopes. 3. Push down on the two front levers until they lock into position.
Using the cut sheet feeder
After loading paper into the cut sheet feeder, make sure the ON LINE light is on. Once the printer is in the sheet feeder mode, a new sheet of paper loads automatically whenever a printable character or line feed command is sent to the printer. When the cut sheet feeder runs out of paper, it stops paper feeding and the PAPER OUT light comes on. To start printing again, load more paper
and then press the ON LINE button. The printer starts printing from the point at which it was stopped. If you turn your printer off during the time the printer detects a paper out or paper jam condition, any data remaining in the printers buffer is discarded.

Software operation

This command causes the printer to eject the sheet in the printer without loading the next sheet: FF form feed
The sheet in the printer is automatically ejected and the next sheet is loaded if the paper reaches the bottom of the print area when any of the following line feed commands is used: LF VT ESC J line feed; advances the paper by one line vertical tab; advances the paper to the next vertical tab position performs line feed in units of l/216 of an inch.

Setting up your software

When you switch between continuous paper and cut sheet feeder paper you usually need to change the settings of your software program. Because of the physical requirements of feeding a single sheet of paper, sheet feeders create a top and bottom margin on each sheet. To work properly, your software program needs to know how many printable lines are available on the page. Paper comes in many different sizes and it is sometimes difficult to know exactly how many printable lines per page you have. When you perform a self test in sheet feeder mode, the printer automatically counts and prints the number of lines that are available on any size of paper. This is the number of lines you should use as the page length in your software setup. See the following section on the self test in cut sheet feeder mode for more details.

Comments: Determines the position (relative to the current position) at which printing of following data will start. To find nl and n2, first calculate the displacement required in 1/12Oths of an inch. Send the resulting number using this formula: total number of dots = nl + (n2 X 256). If the displacement is to the left, subtract the number from 65536 before you use the formula. The command is ignored if it would move the print position outside the current margins. This command applies to both draft and NLQ.
Horizontal tabbing HT Format: ASCII code: HT Decimal : 9 Hexadecimal: 09 Tab Horizontally
Comments: Advances the print position to the next horizontal tab setting. The default settings are at intervals of eight characters in the default character size, and tab positions are not affected by subsequent changes in character size. ESC D Format: ASCII code: ESC D nl n2. Decimal: nl n2. Hexadecimal: 1B 44 nl n2. Set Horizontal Tabs
Comments: This command allows setting of up to 32 horizontal tabs, which are entered as nl, n2, n3, etc. (from 1 to 255) with the 0 character or any value less than the previous one terminating the command. ESC D 0 clears all tabs. The settings on power up or after an ESC @ command are every eight characters. The tab settings do not change if the character size is changed. For proportional printing the size of 10 cpi characters determines the tab positions.
Overall Printing Style ESC x Format : ASCII code: ESC 27 Decimal : Hexadecimal: 1B Select Near Letter Quality or Draft n n n

Proportional Width Table

This table lists the widths of your printers proportional characters. The values given are in 120ths of an inch. (For example, a value of 12 is 12/120ths of an inch.) You may need to enter these widths into a special table for your word processing program so it can calculate the number of proportional characters that will fit on a line. The characters with no code indicated are international characters or graphics. See the table in the section on international character sets in Chapter 3 for the relevant codes for the international characters. Also, see the descriptions of the ESC R and ESC t commands in the Command Summary for information on how to use these characters. The following width table shows each code (hexadecimal), its character, and its width. If there are two numbers in the width column, the second one is for the italic character.
