Note:
Most software programs control the character table and auto line feed. If your software program controls these features, you may never need to set them with the control panel.

Default settings descriptions

Character spacing
When you select 10 cpi, the printer prints 10 characters per inch (cpi). When you select 12 cpi, it prints 12 characters per inch.
Shape of zero
The printer prints the zero character with a slash (0/) when the setting is on, or no slash when the setting is off. The slashed zero makes it easy to distinguish between an uppercase O and a zero.

When this feature is on and you are using continuous paper, the printer leaves a 1-inch (25.4-mm) margin between the last printable line on one page and the first printable line on the next page. This causes the printer to skip over the perforation between continuous sheets.
Most software takes care of the top and bottom margins. Do not turn on skip-over-perforation unless your software does not provide these margins.

Character table
Character tables contain the characters and symbols used by

and auto line feed. Because these settings take effect each time you turn on the printer, they are called default settings.
(3621э/;ркннрй йоллодй ,QNý-HWý3ULQWHUV
(3621ý/;ðêíí
Auto line feed
When the auto line feed feature is on, each carriage return (CR) code is accompanied by a line feed (LF) code. If your printed text is unexpectedly double-spaced, set this feature to off. If text lines print on top of each other, set it to on.
Page length
This option is available only when you use continuous paper with the tractor. You can set the page length to 8.5, 11, 12, or 70/6 inches (the length of A4 paper).
Auto tear off
When you use continuous paper with the push tractor, this feature advances the paper perforation to the tear-off position when you can easily tear off the printed pages. When the printer receives data, it automatically reverses the paper to the top-of-form position and starts printing, so you can use all of the next sheet. When you use the tractor to print on labels, set this feature to off.
Tractor
When you use the tractor as a pull or push tractor, leave this option set to Single. If you install an optional tractor and use both tractors as push-pull tractor, set it to Double.
Interface
When this feature is set to Auto, the printer determines which interface receives data and then switches to that interface until the end of the print job (when no data is received from the selected interface for the amount of time specified by the Auto interface wait time).
Set this option to Parallel only if you want the printer to ignore data from the serial interface. Set it to Serial if you want the printer to ignore data from the parallel interface.
Bit rate, parity bit, data length, and ETX/ACK
These options are available only when the interface is set to Serial.

Changing the default settings

Because software settings always override the printer’s default settings, use your software program to control the printer, if possible. See your software manual for more information. To change the printer’s default settings, follow the steps below:
1. Make sure the printer is turned off and paper is loaded in the paper feeder.
2. Hold down the FONT button and turn on the printer to enter the default-settings mode.
The printer loads a sheet of paper and prints a brief summary and instructions. It instructs you to select the language that you want messages printed in (English, French, German, Italian, or Spanish).
3. Press the FONT button until the FONT lights indicate the language of your choice; then press the LF/FF button to make your selection.

After you press the LF/FF button, the printer prints the current default settings and the next instruction in the language you selected. Wait until printing is finished, then go to the next step.
4. Press the FONT button now to print help text that guides you through the operations. (Once you are experienced with the Printer Setting mode, you can skip this step by pressing LF/FF instead.) The printed instructions include submenu tables that list all of the settings you can change and show you how the control panel lights appear for each selection.
5. At this point you are in the table shown below. To move to the feature you want to change, press the FONT button until the lights indicate the appropriate selection.

Before installing the ribbon cartridge, make sure the printer is not plugged into an electrical outlet.
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.
2. Slide the print head to the middle of the printer.
3. Turn the ribbon-tightening knob in the direction of the arrow to remove any slack from the ribbon so it is easier to install.
5. 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.
6. Slide the print head from side to side to make sure it moves smoothly.
7. Re-install and close the printer cover.
When the 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 remove the cartridge by lifting the posts on either side and taking it out of the printer.
4. 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.

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.
1. Make sure the printer is turned off and the paper-release lever is pushed back to the single-sheet position. Raise the paper guide upright.
Caution:
F
You should use paper at least 210 mm or 8 1/4 inches wide to run the self test; otherwise, the print head prints directly on the platen.

2. While holding down the LF/FF button, turn on the printer. The PAUSE light flashes.
3. Slide the left edge guide until it locks in place at the guide mark. Next, adjust the right edge guide to match the width of your paper.
6. To end the self test, make sure the printer is not printing.
Press LF/FF to eject the sheet; then turn off the printer.
The printer prints characters in each font in the order the fonts appear on the control panel

Most software programs let you specify the type of printer you use so that the program can take full advantage of the printer’s features. Many of these programs provide an installation or setup menu that presents a list of printers.
To take full advantage of your printer’s features, choose LX-300. If LX-300 is not listed, contact your software manufacturer for an update that includes the LX-300. Until you receive an update, choose another printer as close to the top of the list as possible.
LX-300 LX-810 JX-80 Color LX-850 Not color EX-800 LX-800
LX-80/86 FX-850 FX-86e/800
If none of these printers is listed among your program’s options, select the first one available from the following: any FX printer, EPSON printer, and Draft printer.

Your printer can handle continuous paper with a width of 101 mm (4.0 inches) to 254 mm (10.0 inches). Depending on where you position the tractor, you can use it as a pull tractor or a push tractor. These guidelines can help you decide where to position the tractor:
Do you want to switch between printing on single sheets
and continuous paper without removing the paper supply? Will you tear off continuous paper sheet-by-sheet? Use the tractor in the push tractor position. (The printer comes with the tractor installed in this position.) See the following section for instructions.
Are you printing on labels, multi-part forms, or other
documents that require a precise print position? Use the tractor as a pull tractor as described on the next page.

Printing with the push tractor

1. Make sure the printer is turned off. Remove the paper guide and pull the paper-release lever forward to the continuous paper position.
3. Slide the left sprocket unit using the scale on the printer as a guide. The printer prints to the right of the position marked 0. Push the sprocket lock lever back to lock it in place. Then slide the right sprocket unit to match the width of your paper, but do not lock it. Move the paper support so it is midway between the sprocket units.

4. Make sure your paper has a clean, straight leading edge. Open the sprocket covers. Fit the first holes of the paper over the sprocket pins and then close the sprocket covers. Slide the right sprocket unit to remove any slack in the paper and lock it in place. Now the paper is in the paper-park position.
2. Release the sprocket units by pulling the sprocket locks forward.
5. To separate the incoming paper from the printed paper, attach the paper guide by holding it horizontally and fitting its notches over the printer’s mounting posts as shown below. Then slide the paper guide toward the front of the printer until you feel it click.

8. Make sure the printer cover is closed. Press the LF/FF button to feed the paper to the loading position. When the printer receives data, it begins printing automatically.
9. When you finish printing (the printer receives no data for three seconds) the printer feeds the perforation of the continuous paper to the edge of the printer cover so that you can tear off the last sheet. The PAUSE light flashes.
2. Squeeze the tractor’s lock tabs gently and pull the tractor away from the printer.
3. Lift the tractor forward to the mounting slot at the top of the printer and tilt it into place as shown below. When you push the tractor onto the posts, you should feel the notches snap into place.
Note:
Set the Auto tear off feature in the Printer Setting mode to on. Otherwise, the printer does not feed the perforation to the edge of the printer cover.
If the perforation and the edge of the printer cover do not match, adjust the paper position by following the steps in “Adjusting the loading position,” while the

8. Replace the printer cover.
After you install the color ribbon cartridge, run the self test.
If the top or bottom edge of the characters in the self test is a different color from the rest, adjust the ribbon angle. Check the characters printed in red. If the top edge is blue, move the color ribbon adjustment lever forward. If the bottom edge is yellow, move the lever backward. Then print another self test to check your adjustment. Repeat this process until the ribbon is properly adjusted.
Note:
When you print using the color ribbon, the print speed is reduced.
