4 Introduction

If you use an extension cord, make sure that the total of the ampere ratings on the products plugged into the extension cord does not exceed the extension cords ampere rating. Also, make sure that the total of all products plugged into the wall outlet does not exceed 15 amperes. Never push objects of any kind into your printer because they may touch dangerous voltage points or short out parts that could result in a risk of fire or electric shock. Except as specifically explained in the users manual, do not attempt to repair the printer yourself. This could expose you to dangerous voltage points or other risks. Refer all servicing in those compartments to service personnel. Unplug the printer from the wall outlet and have it repaired by a qualified service person under the following conditions: When the power cord or plug is damaged or frayed If liquid has been spilled into it If it has been exposed to rain or water If it does not operate normally when the operating instructions are followed. Adjust only those controls that are covered by the operating instructions since improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the printer to normal operation. If it has been dropped or the cabinet has been damaged If it exhibits a distinct change in performance, indicating a need for service

Unpacking the Printer

Your printer box should include these items.

Printout guide

Paper supports
In some locations, the power cord is attached to the printer.
The printout guide is used with the optional cut-sheet feeder. If you do not have the cut-sheet feeder now, store the printout guide at the back of the printer cover in case you need it later.
Choosing a P/ace for the Printer
When selecting a place to set up your printer, choose a convenient location that provides the following: A flat, stable surface Adequate room around the printer to allow easy operation and maintenance. Make sure its close enough to the computer for the printer cable to reach, and be sure you can easily unplug the power cord. Moderate environmental conditions. Select a cool, dry area and protect your printer from direct sunlight, excessive heat, moisture, or dust. Appropriate power source. Make sure you use a grounded outlet; do not use an adapter plug. Avoid electrical outlets controlled by timers or wall switches; an interruption in power can wipe out the information in your computer or printer memory. Setting Up the Printer
If you place the printer on a stand, follow these guidelines: Use a stand that supports at least 9 kg (19 lb). Never use a stand that tilts the printer. Always keep it level. Provide enough clearance below the stand and between the legs of the stand so your continuous paper flows smoothly. Place cables so they do not interfere with paper feeding; secure them to a leg of the stand if possible.

Assembling the Printer

Follow the steps in this section to get your printer up and running.

Installing the knob

1. Insert the knob into the hole in the printers right side and rotate it slowly until it slips onto the shaft.
Push firmly on the knob until it fits against the printer case.
Attaching the paper supports
1. Raise the paper guide.
Hold one of the wire paper supports and push the tips into the notches on the edge guide
Repeat for the other paper support. Lower the paper guide.
Installing the ribbon cartridge
Before installing the ribbon cartridge, make sure the printer is turned off. 1. Open the printer cover to the upright position, then pull it up to remove it.

Never move the print head while the printer is turned on;
this can damage the printer. Also, if you have just used the printer, let the print head cool for a few minutes before you

touch it.

Slide the print head to the middle of the printer.
Turn the ribbon-tightening knob in the direction of the arrow to remove any slack from the ribbon so it is easier to install.
Insert the ribbon cartridge into the printer as shown; then press both sides of the cartridge down firmly to fit the plastic hooks into the printer slots.
Use a pointed object, such as a ball point pen, to guide the ribbon between the print head and ribbon guide. Turn the ribbon-tightening knob to help feed the ribbon into place; it should not be twisted or creased.
Slide the print head from side to side to make sure it moves smoothly. Reinstall and close the printer cover.
When your printing becomes faint, you need to replace the ribbon cartridge. To remove the old ribbon cartridge, first move the print head to the center of the printer. Then grasp the ribbon cartridge handle on either side and lift it out of the printer.

Plugging in the printer

1. Make sure the power switch on the printer is turned off. It is off when the O side of the switch is pressed down.
Check the label on the bottom of the printer to make sure the voltage required by the printer matches that of your electrical outlet.

Caution:

If the rated voltage and outlet voltage do not match,
contact your dealer for assistance. Do not plug in the

power cord.

3. 4. If the power cord is not attached to the printer, connect it to the AC inlet on the printer. Plug the power cord into a properly grounded electrical outlet.

Running the Self Test

The built-in self test function demonstrates that the printer is working properly. You can run the test with either continuous paper or single sheets; this section describes the easier way, with single sheets.
Caution: You should use paper at least 210 mm (8.3 inches) wide to run the self test; otherwise, the print head prints directly

If you selected the LQ-860, LQ-2550, LQ-570+, or LQ-870 printer, select Sheet Feeder - Bin 1 as the Paper Source. This step is very important for proper page breaks in your documents. Choose the OK button.
10. Highlight EPSON LQ-300 (or the printer you added) and click the button labeled Set As Default Printer. 11. Click the Close button.
Using non- Windows software
From the list of printers box, choose LQ-300. If neither printer is available, choose the first available printer from the following list. If you plan to use color, you must choose either ActionPrinter 3260, LQ-150, LQ-860, or LQ-2550. The other printers cannot use color. ActionPrinter 3260 LQ-150 LQ-860 LQ-2550 LQ-570+ Stylus 800 LQ-870 ActionPrinter 3250 Any LQ printer EPSON printer
If your software does not list the LQ-300, you may want to contact the software manufacturer for an update.

Using the Control Panel

You can control simple printer operationssuch as line feeding, form feeding, loading and ejecting paper, and selecting fontswith the buttons on the control panel. The control panel lights show the printers status and the current font.

Lights

and buttons
Pa use light The orange Pause light is on when the printer stops printing. Each time you turn on the printer, the light flashes briefly. When the printer is out of paper, the light flashes and the beeper sounds three times. The light also flashes when you can tear off the last sheet of continuous paper at the edge of the printer cover. The Pause light goes on and the beeper sounds if an error occurs. Font 1 and Font 2 lights The green Font lights, 1 and 2, indicate the current font setting. For more about selecting fonts, see page 2-4. While in the micro adjust mode, the Font lights flash. See Adjusting the loading position on page 2-5.

Font button Press the Font button during normal operation to cycle through the printer fonts listed on the control panel. When you press the button, the Font lights change to indicate your current selection. For more about choosing a font, see page 2-4. If you hold down the Font button while you turn on the printer, you enter the Printer Setting mode, where you can change many of the printers settings. For more about printer settings, see page 2-22. LF/FF button During normal operation, you can press this button briefly to feed paper line by line. Hold it down to load a single sheet, or to advance continuous paper to the next top-of-form position. You can also press LF/FF to eject a page. If you want to make sure the printer is working correctly, you can also use this button to run the self test. To start the self test, hold down the LF/FF button while you turn on the printer. For complete instructions, see page 1-10. Pause button Press the Pause button to stop the printer temporarily during printing or the self test. Press it again to resume activity. Paper Park Press the Font and LF/FF buttons together to feed continuous paper backward to the paper-park position. See Printing in the push tractor position on page 2-8. Micro Adjust While in this mode, you can adjust the loading position by pressing the LF/FF button or the Font button. See Adjusting the loading position on page 2-5. Using the Printer

Selecting fonts

To choose one of the seven internal fonts listed on the control panel, press the Font button. The two font lights come on (0), go off (), or flash (0) to show the current selection. Press the button repeatedly to cycle through all of the available selections; stop when you reach the desired font. Your selection stays in effect until you change it again or turn off the printer. However, any font choices you make with your software will cancel your control panel selection. The table below shows how the Font lights appear for each selection.

O = on, = off,

= flashing
Printing on Single Sheets
You can use the paper guide to print on single sheets with a width of 182 mm (7.2 inches) to 257 mm (10.1 inches). Note:

Use the table below to select the appropriate paper thickness.
Paper type (Reserved) Standard paper (single sheets or continuous) Multi-part forms I Lever position -1 0

2-sheet

3-sheet
4-sheet Envelopes 20 lb 24 lb (Reserved)
Close the cover. When you finish printing, move the paper-thickness lever back to position 0.
When you choose lever positions 2-6, the print speed is reduced.

Multi-part forms

You can use the built-in tractor to print on carbonless multi-part forms of up to four parts (one original plus three copies). Before you print on the forms, set the paper-thickness lever as described in the previous section. These tips will help you get good results: Load multi-part forms with the tractor only, not in the cut-sheet feeder or paper guide. For instructions, see Printing on Continuous Paper on page 2-7. Use only multi-part forms that are free of wrinkles and waves. Never load multi-part forms joined by metal staples, tape, or continuous gluing. If you need to adjust the loading position, use your software program or change the loading position as described on page 2-5. When you use multi-part forms, raise the paper guide as shown.
If you print on multi-part form without raising the paper guide,

the paper may jam.

labels
You must use the tractor as a pull tractor to print on labels. Keep these tips in mind: Choose labels mounted on a continuous backing sheet with sprocket holes made for use with a tractor. Do not print labels as single sheets, because the shiny backing sheet almost always slips a little. You load labels the same way you load continuous paper, except that the paper-thickness lever should be set to 1. See page 2-13 for loading instructions. Because labels are especially sensitive to temperature and humidity, use them only under normal operating conditions. Make sure the printing stays entirely within the printable area. (See the Appendix for specifications.) Do not leave labels loaded in the printer between jobs; they curl around the platen and may jam when you resume printing. To remove the labels from the printer, tear off the fresh supply at the rear of the printer; then press LF/FF to advance the remaining labels out of the printer.
Never feed labels backward through the printer; they can easily peel off the backing and jam the printer. If a label does become stuck in the printer, contact your dealer.

Envelopes

You can feed envelopes individually using the paper guide. Before loading an envelope, set the paper-thickness lever to position 4 or 5. See page 2-18. To load an envelope, follow the steps used to load single sheets in Running the Self Test on page 1-10. Insert the wide edge of the envelope into the printer first, printable-side down. When you insert the envelope between the paper guides, push it firmly and hold it until it feeds into the printer.

10. Repeat steps 6 through 9 for each additional setting you want to change, or skip to step 11 to exit the Printer Setting mode. 11. When you are finished, turn the printer off. Any settings you have made remain in effect until you change them again.
Installing and Using Options
Single-bin Cut-Sheet feeder
The optional Single-bin Cut-Sheet Feeder (C80637*) handles up to 50 sheets of standard bond paper ( 82 g/m 2 or 22 lb) without reloading. Follow these steps to install the cut-sheet feeder:
1. Make sure the printer is turned off. Remove the paper guide.
2. If the tractor is installed in the pull-tractor position, remove it and reinstall it in the push-tractor position. 3. Make sure the paper-release lever is in the single-sheet position. 4. Hold the cut-sheet feeder in both hands and press on the latch levers. Fit the notches in the cut-sheet feeder over the mounting posts on the printer. Releasing the latch levers locks the cut-sheet feeder in place.
Slide the left edge guide of the cut-sheet feeder so it is aligned with the triangular guide mark. Next, slide the right edge guide to roughly match the width of your paper. Slide the paper support midway between the edge guides.
Pull the paper-set levers all the way forward until the edge guides retract and lock open to allow for paper loading.

2-30 Using the Printer

Take a stack of paper and fan it. Next, tap the side and bottom of the paper on a flat surface to even up the stack.
Do not use envelopes, multi-part forms, carbon paper, or
labels in the cut-sheet feeder.
Insert up to 50 sheets of paper along the left edge guide. Adjust the position of the right edge guide so that it matches your papers width. Make sure the position of the guide allows the paper to move up and down freely.
10. Push the paper-set levers back to clamp the paper against the guide rollers. 11. To reinstall the paper guide, remove the wire paper supports from the edge guides of the paper guide. Insert the two stacker supports packed with the cut-sheet feeder into the notches on the edge guides.
12. Attach the paper guide to the cut-sheet feeder as shown below.
13. Open the printer cover. Place the printout guide in the middle. Close the printer cover. Note:
The printout guide comes packed with your printer, not with the cut-sheet feeder. See Unpacking the Printer on page 1-2.
14. Slide the left edge guide of the paper guide to the center until it stops at the diamond-shaped guide mark. Then slide the right edge guide to the opposite guide mark. You can easily switch between continuous paper and cut-sheet feeder operation. See Switching back to single sheets on page 2-12 for details.
Note: When you print several pages of continuous paper, fold the first
printed page forward at the perforation affer it emerges from below the printer cover. This helps the printer feed the printed

pages properly and prevents paper jams.
To remove the paper guide from the cut-sheet feeder, press both
release tabs and pull out the paper guide.

Pull Tractor Unit

An additional pull tractor (C80030*) is available as an option. You can improve the performance of continuous paper handling by using two tractors at the same time. This is especially useful with continuous pre-printed forms, multi-part forms, and labels. 1. Make sure the paper-release lever is pulled forward to the continuous paper position. Install the built-in tractor in the push tractor position. Install the optional tractor in the pull tractor position. See page 2-13. Load continuous paper on the sprocket units of the push tractor. (See Printing on Continuous Paper on page 2-7.) Turn on the printer. Hold down the LF/FF button to feed paper forward one page.

Using the Printer 2-33

Release the sprocket lock levers of the pull tractor and adjust the sprocket units to match the width of the paper. Be sure that the sprocket units on both the tractors are aligned so that the paper is not crooked. Open the sprocket covers. Fit the holes of the paper over the tractor pins of the sprocket units and adjust the sprocket units as necessary. (See Printing on Continuous Paper on page 2-7.) Close the sprocket covers. If there is slack in the paper between the push and pull tractors, turn the knob on the right side of the pull tractor to remove the slack.
See that the paper is not crooked or wrinkled and lock the sprocket units in place. Reinstall the printer cover and the paper guide.

Color Upgrade Kit

The optional Color Upgrade Kit (C83211*) includes a color ribbon cartridge and a motor unit. Heres how to install the kit: 1. Turn off the printer and remove the printer cover. If the original ribbon cartridge is installed, remove it. Then slide the connector cover on the printer and pull it out as shown.
Install the motor unit in the right hand corner of the printer, with the gear facing the center of the printer. Push it down firmly to fit the metal pins into the slots.
Insert the motor unit plug into the connector on the printer.
Slide the print head to the middle of the printer. Remove the retaining tape from the cartridge and then slide the movable ribbon guide on the color ribbon to the center of the cartridge.
5. Turn the ribbon-tightening knob in the direction of the arrow to remove any slack in the ribbon.
Insert the ribbon cartridge into the printer as shown; then press both sides of the cartridge firmly to fit the plastic hooks into the printer slots.
