Introduction

The ActionPrinter™ T-750 combines all the well-known virtues of previous Epson 9-pin printers with many features normally exclusive to costly 24-pin printers.

The speed of draft printing is 240 characters per second in draft elite and 200 in draft pica. When you have perfected a document, you can switch to one of two Near Letter Quality fonts-Roman or Sans Serif.

Draft printing is extremely fast.

NLQ Roman is clear and typewriter-like.

NLQ Sans Serif is crisp and distinctive.

The SelecType feature gives you access to Near Letter Quality

(NLQ) and condensed print. All you have to do is press the button

for the style you want. While the T-750 is printing, the SelecType

panel shows you what choices it’s using.

If you are using software designed for an IBM@ printer, you have the choice of using the T-750 in Epson mode or IBM printer emulation mode. Even better, you can combine the best of both worlds; the powerful Epson mode commands can now print character graphics like those used by IBM printers and computers.

Loading paper is now easier than ever. Single sheets can be loaded by just moving a lever, and the tractor lets you load a wide range of widths of continuous-feed paper, including labels.

For headings and other emphasis, you can use double-high and

double-wide printing.

Introduction

Chapter 1

Setting Up Your T-750 Printer

Setting up your new T-750 is easy. Simply follow the steps in this

chapter.

1 Unpacking Your Printer

First, remove the printer from the box and take off all outside plastic covering and foam supports. Make sure you have received all the parts shown in the illustration below.

Tilt the tractor cover up and remove the two foam pads underneath it. (These pads protect the tractor unit during shipping; be sure to save them.)

Setting Up Your T-750 Printer

1-1

WARNING

The printer is protected by a print head protector, a platen protector

and two locking tabs during shipping. These protective items must be

removed before you turn on the printer. Follow the steps in Figure 1-2.

Also, you should install the paper feed knob. To install the knob,

simply push it onto the shaft on the right side of the printer as shown

in Figure 1-2.

Figure I-2.

Protective items

Print head protector

1. Remove the left locking tab.

2. Remove the print head protector.

3. Move the print head to the left.

4. Remove the right locking tab and the platen protector.

2 Selecting the Right Location

The most important consideration in choosing a location for your

printer is that it be close enough to connect a cable to your computer.

But also keep the following tips in mind:

1-2

Setting Up Your T-750 Printer

l Place the printer or printer stand on a solid and level foundation.

Avoid setting it on carpet or on unstable surfaces such as chairs.

l Use a grounded outlet-one that has three holes to match the power

plug on the printer. Don’t use an adapter plug.

Avoid using electrical outlets that are controlled by wall switches. If you accidentally turn off a switch, you could wipe out valuable information and stop your printing.

Keep your printer and computer away from base units for cordless telephones.

Avoid using an outlet on the same circuit breaker with large

electrical machines or appliances that might disrupt the flow of power to your printer.

l Choose a place that is clean and away from moisture, dust, and

excessive heat (such as a heater or direct sunlight).

If you are going to use continuous-feed paper, clear enough space around the printer so that the paper has an unobstructed path in and out of the printer. There are three common methods of arranging a printer and continuous paper:

Using a printer stand with the paper stacked underneath it.

l Using a desk or table as a stand, with the printer near the rear edge

and the paper on the floor or on a shelf.

l Putting the printer on a desk or table and stacking the paper behind

the printer.

Installing the Ribbon

To install the ribbon, follow the directions below:

1. Remove the tractor cover that comes installed on the printer. TO remove it, simply pull the back of the cover toward you until the

cover is vertical. Then lift it up and off the printer.

2. Manually moved the print head to the middle of the platen.

Setting Up Your T-750 Printer

1-3

WARNING

The power must be OFFwhen you move the print head. Moving the print head when the power is ON may damage your printer. If you’ve been using your printer just before changing the ribbon cartridge, be careful not to touch the print head because it becomes hot during use.

3. Before installing the ribbon cartridge, turn the small knob on top in the direction of the arrow to tighten the ribbon as shown in Figure l-3.

Figure 1-3. Tightening the ribbon

4. Hold the cartridge by the two plastic tabs. Lower the cartridge into the printer, guiding the two pins on each end of the cartridge into the slots in the printer frame, as shown in Figure 1-4. Press firmly on each end of the cartridge to make sure the pins are firmly seated in the slots,

5. Now use the point of a pencil to guide the ribbon into place between the ribbon guide and the print head as shown in Figure l-5. (There is also a diagram on the top of the ribbon cartridge itself.)

6. With the cartridge in place, again turn the ribbon knob in the direction of the arrow to tighten the ribbon.

And that’s it-the ribbon is now installed.

Replacing the ribbon...

When buying new ribbon cartridges for the T-750, be sure you get

a ribbon specifically for Epson T-750 or FX series printers. Ribbon

cartridges for other Epson printers, such as the L-1000 or LQ series,

closely resemble T-750 ribbons, but their use can cause poor print

quality. Also, the Epson ribbon replacement pack #7755 should not be used as a replacement ribbon.

The T-750 uses a continuous-loop, inked fabric ribbon (#8755).

When your printing becomes too light, replace the ribbon with a fresh cartridge. To replace the ribbon, just pull up on the two plastic

tabs on the ribbon cartridge and lift it out of the printer. To install a

new ribbon, follow the preceding steps.

4 Loading Continuous-feed Paper

When you receive your T-750, it is set up to print on continuous-feed

paper. If you plan to use single-sheet paper, turn to Chapter 2 for

instructions on setting up the printer for single sheets. If you have

bought the optional automatic sheet feeder, complete the remainder of

the setup steps before you install the automatic sheet feeder (which has its own manual).

The T-750 tractor units are adjustable to accommodate different widths of paper, from 4 to 16 inches. Before you load continuous-feed paper, prepare the printer in the following manner:

1. Make sure the printer is turned off.

2. Remove the tractor cover that comes installed on the printer. To

remove it, simply pull the back of the cover toward you until it is

vertical. Then lift the cover up and off the printer.

3. Install the paper rest as shown in Figure l-6. This part helps prevent

the paper from catching on the printer cable.

1-6

Setting Up Your T-750 Printer

Figure 1-6. Installing the paper rest

4. Pull both the paper release lever and the paper bail lever toward the front of the printer. (Figure 1-6 shows where these levers are.)

Setting Up Your T-750 Printer

1-7

Now you are ready to load the continuous-feed paper. Just follow the

steps below:

1. Using Figure 1-7 as a guide, pull the locking levers on the pin-feed holders forward so that you can move the holders to the left and right.

Figure 1-7.

Pin-feed locking levers

2. Move the left holder so that the locking lever is about l/4 inch

from the left side and push the locking lever back to lock that

holder in place. Leave the right holder unlocked.

3. Open the pin-feed covers as shown in Figure l-8.

WARNING

Do not use the pin-feed covers to move the pin-feed holders,

Figure 1-8.

Open pin-feed cover

4. Guide the paper into the paper slot, and push it through until it comes up between the ribbon guide and the platen. (Moving the paper with a side-to-side motion makes it easier to push the paper through.)

5. Pull the paper up until the top is above the pin-feed holders. Fit the holes on the left side of the paper over the pins in the left holder (as shown in Figure l-9) and close the cover.

Figure

1-9.

6. Fit the right side of the paper into the right holder, moving the holder as needed to match the width of the paper.

7. Close the right cover, making sure the paper has

dips or wrinkles

and lock the right holder in place.

Now that you have loaded the continuous-feed paper, prepare the

printer for printing.

1. Push the paper bail lever back.

2. Hold the paper guide above the printer. Insert the right hinge tab into the right tab slot, as shown in Figure l-10. Then insert the left tab into the left slot and push the guide back so that it is horizontal.

Figure 1-10.

Installing the paper guide

This guide keeps paper that is coming out of the printer from interfering with the paper going in. The guide is also used in the upright position for printing on single sheets of paper.

1-10

Setting Up Your T-750 Printer

3. With the printer turned OFF, advance the paper with the paper feed knob on the right side of the printer until the first row of

perforations is about even with the top of the ribbon. (See Figure 1-11.)

Figure 1-11.

Setting top of form

This is the top of form position. It makes your printed pages end where you want them to and prevents the printer from printing on the perforations. The paper should be in this position when the power is turned on or when software initializes the printer or sets the page length.

4. Replace the tractor cover.

Loading single-sheet paper...

The T-750 can also accommodate single-sheet paper. It can be

loaded one sheet at a time as shown in Chapter 2 or by using the

optional automatic sheet feeder. Chapter 2 also contains

information on how to remove and reinstall the tractor feed unit. The printer cover that comes packaged with the T-750 is for use

with single-sheet paper.

Setting Up Your T-750 Printer

5 Turning On the Printer

Before plugging in the power cord, see that the power switch near the back of the left side of the printer is turned off; then plug the power cord into a properly grounded socket.

WARNING

Before turning on the printer, be absolutely sure you have removed all packing materials. Turning on the printer when the print head cannot move may seriously damage the mechanism.

Now, turn the power ON with the switch on the left side of the

printer. When you turn on the printer, three things happen:

l The print head moves back and forth and stops at the left side of the

printer; this is the home position.

The printer is initialized and set to certain default settings (which are

fully described in Appendix D).

l The green power light on the control panel comes on.

6 Operating the Control Panel

The control panel is shown in Figure l-12.

Figure

1-12.

The T-750 control panel

1-12

Setting Up Your T-750 Printer

The three buttons nearest the front of the printer control advancing the paper and communication with the computer. The four indicator lights show when the printer is turned on and when it is ready to use.

The buttons

There are three large buttons on the control panel.

OFF LINE/ ON LINE

FORM FEED/ ROMAN

LINE FEED/ SANS SERIF

The green light next to this button indicates that the printer is able to receive and print data from the computer. When the light is off, the printer is off line and cannot receive any data. Press the button to change from on line to off line or from off line to on line. The printer automatically goes off lined when you try to print without paper in the printer. Pressing the button then has no

effect until you load paper. When the printer is off line, this button ejects a

single sheet of paper or advances continuous paper to the next top of form. When the printer is on line and in NLQ mode, pressing the button selects the Roman font.

When the printer is off line, this button advances the paper one line each time you press it or continuously if you hold it down. When the printer is turned on, use this button to advance paper. When the printer is on line and in NLQ mode, pressing the button selects the Sans Serif font.

Note

Use the paper feed knob on the right side of the printer only when the

printer is turned OFF. Using it when the printer is on can damage the printer mechanism.

light, the printer has three other lights.

1-13

PAPER OUT

Also on the control panel are two touch switches that let you choose

the print style and size. These are the SelecType buttons, which are

described in the next section.

SelecType

The SelecType feature consists of two buttons on the control panel. These buttons select the most used printing features-Near Letter Quality (NLQ) and condensed.

With the two SelecType buttons, you can produce any of the four

typestyles shown below:

Draft printing is extremely fast.

NLQ is clear and typewriter-like.

This comes on when the printer is out of paper.

Draft can be condensed.

NLQ can also be condensed for more characters on a line.

Draft is for fast printing and NLQ for higher-quality work. In the

condensed mode all characters are about 60% of their normal width.

Two NLQ fonts are available: Roman and Sans Serif. You select

them by using the FORM FEED and LINE FEED buttons while the printer

is on line. The button selects Sans Serif. A software command to change the NLQ typeface is also available in the Epson mode.

FORM FEED

want to turn off either mode, press its button again. It beeps once and the indicator light turns off to show that the mode is cancelled.

As you can see, SelecType makes it easy to choose either NLQ or

condensed, and the indicator lights always tell you which modes you’ve

selected.

Trying out SelecType is a simple three-step process:

1. Create a short sample document or file with your favorite application program.

2. Press either or both of the SelecType buttons.

3. Print the document or file using your application program’s print command.

If SelecType does not work

Some applications programs are designed to control all typestyle functions. Before each printing operation, these programs cancel all previous typestyle settings by sending a signal (INIT) or by sending specific control codes to cancel certain typestyles. These signals or control codes may cancel your SelecType settings.

One reset signal, however, does not affect your SelecType settings. This is the ESC @ command.

You can see whether your program is changing your settings by watching the buttons when printing starts. If the lights change, the

program is controlling the typestyles.

If your application program changes your SelecType settings, you

have two choices:

1. Use the program’s setup procedure (which could be called by another name, such as install) to remove the codes that interfere with your SelecType settings.

2. Use the print control codes for your application program instead of SelecType to control your printing. Most programs that cancel SelecType settings also have sophisticated print control commands that give the same results that SelecType does. The manual for your program should explain the necessary commands.

Setting Up Your T-750 Printer

1-15

Note

Also remember that control codes in your document will override the SelecType settings. Therefore, if you have a code for NLQ in your document and you press the

DRAFT

SelecType button, your printing

will still be in NLQ.

8 Running the Self Test

The T-750 has a built-in self test that prints out the characters in its

memory so that you can see that the printer is working properly.

The self test also prints the settings of the printer’s DIP switches.

You’ll use this part of the printout in the last section of this chapter.

Before running the self test, make sure that the

power

is OFF and paper is loaded in the printer. (Use wide paper to avoid printing on the platen.)

To run the self test in the Near Letter Quality (NLQ) mode, hold

down the

The self test first prints the version number of the printer and several

lines of settings that are explained in the last section of this chapter.

Then it prints the characters from its memory. The test continues until

you turn the printer off. Part of a typical self test is shown below.

9 Connecting the Printer to Your Computer

Your T-750 printer communicates with your computer through a Centronics® compatible parallel interface. If your computer uses this type of interface and you have a suitable cable, you can connect your computer immediately. (Be sure that your cable is a shielded cable.)

If you do not know what kind of interface your computer requires, consult its manual. For further information on the standard interface, see Appendix E.

The parallel interface

Before connecting a parallel interface cable, see that both the printer

and computer are turned off. Then plug the connector into the printer.

Next squeeze the clips gently and click them into place.

Some parallel cables have a ground wire. Connect this wire to the ground screw on the printer to protect data from interference. Then plug the other end of the cable into the computer and connect the ground wire on the computer end of the cable if it has one. Figure 1-13 shows a properly connected parallel cable.

Figure 1-13. Connecting a parallel cable

10 Choosing the Operating Mode with DIP Switches

The T-750 has 12 switches that allow you to change many of the printer’s settings to suit your individual needs. You may need to change one or two of them now. These switches, known as DIP (Dual In-line Package) switches, are in the back of the printer. See Figure 1-14.

Figure 1-14. DIP switch location

The switches are in two groups and are numbered, as shown in

Figure 1-14. As you can see in the example below, the first part of the self test shows the settings of the switches. You will find your own self test printout helpful as you use this section.

Setting Up Your T-750 Printer

Before you change any to give you easy access to the switches. Then you can easily turn the switches on and off with a thin pointed object, such as a small screwdriver or the cap of a ballpoint pen. The switches are ON when they are UP and OFF when they are DOWN.

Note

When you change a DIP switch setting, turn off the power, reset the switch or switches, then turn on the power again. The printer checks

and recognizes new settings only at the time you turn the power on.

The operating mode

The T-750 has two operating modes, ESC/P® and IBM printer emulation mode. ESC/P stands for Epson Standard Code for Printers, a powerful set of commands developed by Epson and supported by almost all application software for personal computers. This is the mode that you should find the most useful and valuable for your printing. The rest of this manual refers to the ESC/P mode simply as the Epson mode.

The IBM printer emulation mode is for software that is designed only for IBM printers. It is not necessary to use this mode for your T-750 to be compatible with IBM computers. As you can see from the list of Epson and IBM printer emulation mode commands in Appendix A, the Epson mode has more commands and many more capabilities.

DIP

switch settings, turn the printer around

There are only two cases in which you may want to use the IBM printer emulation mode:

1. Your software lists only IBM printers in its printer selection menu.

2. You need to use the following characters and your application software will not print them in the Epson mode:

If you select IBM printer emulation mode with the DIP switch and choose an IBM printer in your software’s printer selection menu, your T-750 will behave as an IBM printer does. You can use most software that supports IBM printers, but you will notice that the commands do not allow you access to all the features of your Epson printer.

Setting Up Your T-750 Printer

1-19

DIP switch 14 controls the choice of operating modes. Turning the switch OFF selects Epson mode, and turning it ON selects IBM printer emulation mode.

The Epson character graphics set

Half of the characters used by IBM PCs and compatibles are special character graphics and international characters. Most previous Epson printers printed italics instead of these characters. With the T-750, however, you can print the character graphics without losing italics or any of the power of the Epson commands.

DIP

switch l-3 controls the choice between the italic and the

character graphic table (called CG table in the DIP switch printout).

Turning the switch ON selects the character graphic table, and turning

it OFF selects the italic table. Remember that italics are available even if you select the character graphic table.

Making the choice

The decision you make about the operating mode and the character

graphics set depends upon the software you use. For most applications, choose the Epson mode and the Character Graphics set (DIP switch

l-4 OFF and DIP switch 1-3 ON). That way you can set up your

software for an Epson printer and have the full power of the Epson

commands.

If you have trouble printing italics, change DIP switch 1-3 to OFF to choose italics instead of character graphics. On the other hand, if you have trouble printing character graphics, change the printer to IBM printer emulation mode by setting software to match.

DIP

switch l-4 ON and set your

WARNING

You must always be careful to set up your printer and software to match. Although the IBM commands are based on some of the Epson commands, important differences affect much software. These differences can cause erratic printing. In particular, line spacing and page layout are likely to be wrong, and extra characters may appear.

Other DIP switch settings

Appendix D summarizes all the DIP switch settings in a group of

tables. See that appendix for reference and further information.

Setting Up Your T-750 Printer

Chapter 2

Choosing and Loading Paper

The T-750 printer can accommodate many different sizes and types

of paper, using either its automatic single-sheet loading feature or its

adjustable tractor.

The easy-to-use tractor can handle a wide range of paper widths, and the automatic single-sheet loading feature handles individual sheets quickly and easily. For greater efficiency with individual sheets you can add an optional automatic sheet feeder.

Choosing Paper

Without any accessories, you can use single-sheet paper from 7¼ to 14½ inches wide and continuous paper from 4 to 16 inches wide, including the perforated edge strips.

Carbon copies

If you use multi-part forms or carbon copies in the T-750, use no more than three sheets or parts at a time, with a total thickness of no more than 0.17 mm. Also change the paper thickness setting as described at the end of this chapter.

Using Single-sheet Paper

The automatic sheet loading feature of the T-750 gives you short printing times by combining fast loading with fast printing.

If you print large amounts on single sheets of paper, however, you

may find it more convenient to use an automatic sheet feeder. This is

an optional device that holds a stack of paper and inserts a new sheet

whenever required, making single sheets as easy and convenient to use

as continuous paper. The automatic sheet feeder has its own user’s manual.

Choosing and Loading Paper

2-1

Before you load single-sheet paper the first time, you must prepare the printer by removing the tractor unit and installing the paper guide, as described in the next five steps. (If you have previously loaded continuous-feed paper, you have already done some of the steps.)

Preparing the printer

1. Remove the tractor cover that comes installed on the printer. To remove it, simply pull the back of the cover toward you until it is vertical. Then lift the cover up and off the printer.

2. Be sure that you have removed the protective items as described on page l-2.

3. Remove the tractor unit. Simply press the release levers (shown in Figure 2-1) with your thumbs, rock the tractor unit back, and lift it off the printer.
