    Epson printers-and more too. LQ-1500 Features The LQ-1500 is designed to be used day in and day out in an office environment. Its size and rugged good looks proclaim this fact. Its Epson engineering guarantees it.

  • Page 10: About This Manual

    The LQ-1500 is a sophisticated machine. Although it is simple to operate, writing programs for it can be complicated. In many cases, the people who use the LQ-1500 are not the ones who do the program- ming. Therefore, Epson has provided two different manuals. This LQ-1500 User’s Manual contains all the information required to set up...

  • Page 11: Finding A Suitable Location

    Finding a Suitable Location Before you actually set up your printer, you should give some thought to where you are going to put it. Of course, your printer must sit somewhere near your computer (the length of the printer cable is the limiting factor).

  • Page 12: Unpacking The Lq-1500

    Fig-we 1-1. Unpacking the LQ-1500 during operation. Here are some additional suggestions to follow: 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).

    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.

  • Page 20: Installing The Sheet Guide, Assembling The Three Pieces, Attaching The Sheet Guide

    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.

    Now, lift up slightly on the card and secure it in place with the screws provided. If you use your LQ-1500 with different computers, you may have to remove and replace this card. Begin by removing the retaining screws. Then pull release levers same time.

  • Page 27: Setting The Dip Switches, 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.

  • Page 28: Interface Connection To Computer

    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 to set these switches. You can use a ballpoint pen to reach into the interface slot and change switch settings.

  • Page 35: Maintenance, Cleaning The Lq-1500

    Maintenance As with any mechanical device, the best maintenance of your LQ-1500 is preventive maintenance. You’ve already started by choos- ing a clean, dust-free location with a comfortable temperature range. Of course, you will change your ribbon cartridge whenever it loses quality through use.

    LQ-1500 uses. Types of Paper and Paper Feeders You can use a great variety of paper types with the LQ-1500 which makes your printing both flexible and convenient. Paper thickness can range from 0.07 mm to 0.20 mm for both types of paper feeders.

  • Page 38: More Printer Parts, Platen Release Lever, Adjustment Levers

    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.

  • Page 39: Print Head Adjustment Lever, Loading Single-sheet Paper, Preparing The Printer For Single-sheet Feed

    Loading Single-Sheet Paper Printing on single-sheet paper is fast and easy with the LQ-1500. The printer does most of the work and does it the same way every time. Your main responsibility is to set each sheet of paper in the sheet guide unit evenly and press the correct button.

  • Page 40: Loading Single-sheet Paper

    If the printer is OFF, turn it ON. The PAPER OUT light should be off. If it is on, then the paper is not down in the printer far enough or it is not far enough to the left side of the platen.

  • Page 41: Paper Feed Knob, Sheetload

    WARNING: Do not move the paper backward through the printer because it may damage the paper-out detector. Return the printer to the on-line mode by pressing the ON LINE button. The ON LINE and READY lights should now be on.

  • Page 42: Removing Single-sheet Paper, Loading Pin-feed Paper, Installing The Tractor Unit

    Loading the LQ-1500 with pin-feed paper is not difficult, but it does require that you have the optional tractor unit purchased separately from your dealer. As with single-sheet feed, the printer does most of the work and virtually takes care of itself until the paper runs out.

  • Page 43: Preparing The Printer For Pin-feed Paper, Protective Cover Removed

    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.

    5. Make sure the platen release lever is closed (back). Inserting pin-feed paper Now that you have prepared the printer, you can load the pin-feed paper by following these steps: 1. Make sure you have a clean top edge. Insert the pin-feed paper into the paper guide slit at the rear of the platen as shown in Figure 3-6.

  • Page 46: Paper Inserted

    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.

    The LQ-1500 Self-Test Now that you are an expert on loading your LQ-1500, you’re ready to print. The LQ-1500 self-test is a built-in program which generates a complete printing of all standard characters. The self-test also pro- vides an opportunity to test the ribbon and paper installation without having to request a printout from your computer.
