Introduction Congratulations! You’ve purchased the Epson LQ-1500 TM . This advanced, state-of-the-art printer combines the quality of typewriter print with the speed of a dot matrix printer. Of course, it has all the capabilities of the other Epson printers-and more too. LQ-1500 Features The LQ-1500 is designed to be used day in and day out in an[...]

l High-resolution graphics. The LQ-1500 has all the graphics capabi- lities of the FX series of printers and more. The 24-pin print head provides top-quality, high-resolution graphics. l Text buffer. The LQ-1500 has a 2048 character text buffer to increase printing speed. The buffer takes information quickly from your computer, leaving the computer[...]

Chapter 1 Setting Up Your LQ-1500 You’ve just purchased a terrific new printer, and dug far enough into the box to find this manual. Now what? In this chapter we’ll show you how to set up your LQ-1500 and connect it to your computer. First, take inventory. Carefully unpack the carton and make sure that you have all of the pieces shown in Figure[...]

Fig-we 1-1. Unpacking the LQ-1500 during operation. Here are some additional suggestions to follow: 1. Place the LQ-1500 on a flat, stable surface. The printer will make more noise if you place it on a table that moves or vibrates. 2. Connect the printer to a grounded electrical outlet (do not use an adapter plug). It’s a good idea to choose an o[...]

5. Use the LQ-1500 in areas that are comfortable for you. If you find it too hot, too cold, or too humid, the environment is not right for the LQ-1500; it may not operate properly. Figure 1-2. Paper placement Getting to Know Your Printer Now you’ve got a small collection of odd-shaped pieces placed in a suitable location. The next step is to put [...]

Figure 1-4. Paper feed knob Removing the dust cover The dust cover is the brown plastic cover which keeps dust out of the print mechanism and reduces the noise level when the printer is on. If you are using the optional tractor unit, you will not use the dust cover. Lift off the dust cover. It just sits in a recess on the top of the printer so remo[...]

Figure 1-5. Removing the front cover Discovering what’s inside Now that you can see the insides of the printer, take a few moments to find some of the parts that you need to know about. Study Figure 1-6 until you can identify these parts: The print head is probably the easiest part to locate, so start with it. The print head is the large, black, [...]

Figure 1-6. Printer parts Once you identify these parts, you will know enough about the printer to get started. This manual will help you identify other parts as the need arises. Installing the Ribbon Cartridge The LQ-1500’s ribbon cartridge is easy to install, and it won’t get your hands dirty. Follow these steps for a quick installation. 1. C[...]

Figure 1-7. Ribbon cartridge 4. Hold the ribbon cartridge in both hands to position it over the print head (the hole in the ribbon cartridge fits over the finned part of the print head). The short piece of exposed ribbon must go between the print head and the ribbon guide so that the ribbon does not rest directly against the platen (see Figure 1-8)[...]

Figure 1-8. Ribbon installation Figure 1-9. Ribbon operation To replace the front cover, simply reverse the steps you took to remove it. Fit the right end into place first and then lower the left end until it is securely in place. Tilt the cover back into the closed position. It should fit snugly. 11[...]

Installing the Sheet Guide The sheet guide serves a dual purpose on the LQ-1500. If you are using single sheets of paper, the guide ensures consistent margins and straight lines of print. If you are using pin-feed paper, the sheet guide is used as a paper separator to keep the incoming and outgoing paper from interfering with each other. Assembling[...]

Figure 1-10. Sheet guide assembly 13[...]

Figure 1-11. Paper guide position Figure 1-12. Sheet guide installation If you plan to use your LQ-1500 with single sheets of paper, lift up the sheet guide at the back and fold down the metal legs on the bottom of the sheet guide. As shown in Figure 1-13, the legs fit into slots in the top case of the LQ-1500. (This step is not necessary if you wi[...]

Figure 1-13. Printing single sheets Once the sheet guide is installed you can replace the dust cover on top, as shown in Figure 1-14. Also, you may want to remove the pro- tective film that is on the switch panel at the right front of the LQ-1500. This film protects the switch panel during manufacture and shipment and can be easily peeled off. Conn[...]

Figure 1-14. The dust cover Figure 1-15. Interface card 16[...]

Installing the interface card Your dealer may have already installed the interface card for you. Turn your printer around and look at the back of the printer to tell if the interface card has been installed (see Figure 1-16). If there is a large cavity at the lower left, the interface card is missing and you must install it before you can use your [...]

The installation procedure is the same for all three of the available interface cards. The card is easily mounted or removed. The only tool you need is a Phillips screwdriver. To install the interface card slide it into the cavity on the back of the LQ-1500 as shown in Figure 1-17. It should slide between the upper and lower plastic guide rails on [...]

Figure 1-17. Interface card installation Setting the DIP Switches This is the last step in installing your printer. Because each com- puter installation is slightly different, Epson has placed a series of DIP switches on the back of theprinter interface, which you can change to best suit your printing application. You can see them through a slot in[...]

Figure 1-18. Interface connection to computer WARNING: The DIP switches we are discussing are in the interface unit on the back of the printer. Do not change the set- tings of the DIP switches that are inside the printer. These settings have been determined by the manufac- turer to be correct for this LQ-1500 printer. Special knowledge is required [...]

second digit refers to the individual switch number. It is printed right on the switch itself. You can also see that there is a small arrow on the left side of the switch group which indicates the ON position for these switches. However, it’s easier to remember switch settings according to whether the switch is pointing up (toward the top of the [...]

You can use the bell to signal wh[...]

Chapter 2 Operation and Maintenance Your LQ-1500 is now set up. You’ve connected it to your computer and set the switches. Now you’re ready to learn how to use the con- trols and indicators on the printer to operate it correctly. We’ll also give you some advice on how to maintain your LQ-1500 and keep it printing smoothly for a long time. The[...]

Power switch Figure 2-1. Controls and indicators l PAPER OUT light -- glows red when the printer is out of paper; printer will stop printing (if Switch 1-2 is in the up position). l ON LINE light -- glows green when data reception is possible. l ON LINE button -- allows you to switch from on-line to off-line status (this is a toggle). When the prin[...]

l LF button -- stands for line feed. When you’re off line, tapping this button advances the paper one line at a time. To advance multiple lines, hold down the LF button. Do not perform continuous line feeds for more than two minutes. l SHEET LOAD button -- opens the paper bail and loads single- sheet paper into the printer. The paper-out detector[...]

You should also clean the inside front portion of the printer (Figure 2-2) to get rid of dust and paper lint. To do this, turn the power switch off and disconnect the power cord. Remove the dust cover, the front cover, and the ribbon cartridge. Use a small vaccum cleaner and a soft brush to clean inside the printer. Be careful not to bend or damage[...]

Chapter 3 Installing Paper and Paper Feeders Now that you are more familiar with your LQ-1500, you’re ready to install and load the paper feeders. Since you’re into the third chap- ter, you’re probably getting anxious to print something by now. First, you need some facts on the different types of paper and paper feeders the LQ-1500 uses. Type[...]

More Printer Parts You also need to become familiar with two other important printer parts before you attempt to load any type of paper. Remove the dust cover and open the front cover to find and identify these parts: the platen release lever and the print head adjustment lever. Platen release lever The platen release lever controls the pressure of[...]

The second setting, released, is used when the tractor unit is in place. The platen release lever is pulled forward toward the front of the printer. In this position, the friction rollers do not catch the paper but allow it to move freely through the paper path. The tractor unit is installed above the platen and draws the paper through by its pin h[...]

2. Install the sheet guide unit and place it in the upright position (see Chapter 1 for details). Line up the left edge of the left sliding guide with the 1 on the paper bail. This is very important because paper near the center or the right side of the platen will not be detected by the printer. 3. Be sure that switch 1-2 is in the up position to [...]

Paper Figure 3-2. Sheet load Note: If the paper does not advance far enough to be held by the paper bail, turn OFF the power, remove the dust cover, open the paper bail, and use the paper feed knob to advance the paper to the proper position. This problem is caused by not having the paper far enough down in the printer when you press the SHEET LOAD[...]

Removing single-sheet paper To remove single-sheet paper from the printer, set the printer in the off-line mode by pressing the ON LINE button (remember its’s a tog- gle). The ON LINE and READY lights should now be off. Press the FF (FORM FEED) button and the paper will be ejected from the printer. Loading Pin-feed Paper Pin-feed paper is used qu[...]

Figure 3-3. Protective cover removed 5. Gently tilt the tractor unit toward you and push the tractor unit down until you feel it lock into place. Preparing the printer for pin-feed paper With the tractor unit now installed, you can prepare the printer to load the pin-feed paper. Follow the steps outlined below and refer to Figure 3-5. 1. Set DIP sw[...]

Figure 3-5. Printer parts used with pin-feed paper 4. Set the paper support skids evenly from the approximate center of the paper width (as shown in Figure 3-6). This helps the paper feed smoothly. Note: If you are using narrow or standard width paper, you must insert it at the far left of the platen (just as you did with single- sheet paper). 5. M[...]

Advance the paper by turning the paper feed knob clockwise. With the platen release lever closed, the paper should easily catch on the platen and be fed through. Figure 3-6. Paper inserted Note: If the paper is not feeding correctly (or easily), stop, turn the paper feed knob counterclockwise, and at the same time gently pull the paper back out. Ch[...]

Figure 3-7. Aligning pin frames Note: Position wide paper so that the printable surface is between 1 and 136 on your paper bail (the holes will be outside of these margins on the left and right). 5. Lock the pin-feeders in place by pushing the gray pin-feeder lock levers back. 6. Confirm that the tractor pins are centered in the paper pin-holes and[...]

Figure 3-8. Pin-feeder covers Proper placement of pin-feed paper When using the LQ-1500 with pin-feed paper, we recommend that you arrange your stack of paper in one of two ways. First, if you use a stack of paper and have to place it behind the printer, make sure that it is not higher than the surface of the sheet guide unit. Placing the paper beh[...]

Chapter 4 Control Codes This chapter introduces you to the control codes you can use to send instructions from your computer to your printer. If you already know how to program your printer, you’ll want to know how control codes work with the LQ-1500. You’ll also be interested in Appendixes A and E which provide the control codes. Please note t[...]

and some of the LQ-1500’s functions. Because of these standard codes, you can use your LQ-1500 printer with virtually any kind of com- puter without having to worry about their ability to talk to each other. Your LQ-1500 printer can communicate with any computer that uses ASCII. How Many Names Can One Code Have? Although these codes are standard [...]
