Chapter 2

Paper Handling
This chapter covers the basic instructions you need to load and use continuous paper, single sheets, and special paper such as multipart forms and labels.
Printing on Continuous Paper
You can print on continuous paper using the tractor in either the push or pull position: Use the tractor in the push position if you want to be able to switch between printing on single sheets and continuous paper without removing the paper supply, or if you will be tearing off continuous paper sheet-by-sheet. (Follow the instructions in the next section.) The printer comes with the tractor installed in the push position. Use the tractor in the pull position if you will be printing on labels, multipart forms, or other documents that require a precise print position. (See Printing with the pull tractor on page 20 for instructions.)
Printing with the push tractor
Follow these steps to load continuous paper on the push tractor: 1. 2. Turn off the printer. Remove the printer cover and the paper guide, and pull the paper release lever forward to the continuous paper position.
Unlock the sprockets on the tractor by pulling the blue lock levers forward.
Slide the left sprocket so the pins are above the 0 mark on the printer scale (beneath the tractor). The printer starts printing to the right of the position marked 0.

0 mark

Push the lock lever back to lock it in place. Then slide the right sprocket to match the width of your paper, but do not lock it. Move the paper support so it is midway between the sprockets. Stack your continuous paper behind the printer. Make sure there are no obstructions between the paper and the printer, and that the paper is aligned squarely with the printer so it will feed in straight.
Make sure your paper has a clean, straight, leading edge. Then open the sprocket covers and fit the first holes of the paper over the sprocket pins.
Close the covers. Slide the right sprocket to remove any slack in the paper and lock it in place. To separate the incoming paper from the printed paper, attach the paper guide by holding it horizontally and fitting its notches over the printers mounting posts as shown below. Then slide the paper guide toward the front of the printer until you feel it click.
10. Replace the printer cover and close it. 11. Turn on the printer. 12. When using the push tractor, it is a good idea to turn on the Auto tear off feature in Default Setting mode. See Changing the Printers Default Settings on page 36. 13. Press the LF/FF button to feed the paper to the loading position. When the printer receives data, it begins printing automatically.

Pull the paper release lever forward to the continuous paper position. To remove the tractor from the push position, gently squeeze the lock tabs on both sides and then rotate the tractor up to pull it away from the printer.
Lower the tractor onto the mounting slots at the top of the printer as shown below, and tilt it back until you feel it lock into place.
Unlock the sprockets by pulling the blue lock levers forward.
Feed the paper into the rear paper slot as shown below, and pull it up. Position the paper using the scale on the printer as a guide. Printing starts to the right of the position marked 0 (under the paper now).
Slide the left sprocket so its pins are aligned with the holes in the paper and push the blue lock lever to lock the sprocket in place. Then slide the right sprocket to match the width of your paper, but do not lock it. Move the paper supports midway between the two sprockets.
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 to remove any slack in the paper and then lock it in place.
Note: Remove any remaining slack by gently pulling the paper from the back. 10. To separate the incoming paper from the printed paper, attach the paper guide. Hold it horizontally and fit its notches over the printers mounting posts. Then slide the paper guide toward the back of the printer until you feel it click. 11. Turn the paper feed knob to adjust the paper position. The perforation between pages should be just above the print head. 12. Replace the printer cover but leave it open. 22 Paper Handling
13. Turn on the printer. 14. Set the Auto tear off feature in the Default Setting mode to Off; otherwise, the paper may jam. (See page 36 for more information.) When the printer receives data, it begins printing automatically. If you want to change the position where printing begins on the page, press the LF/FF button to advance the page to the next top-of-form position, and then see the next section to adjust the loading position. To eject the paper, tear off the paper entering the printer; then press the LF/FF button to feed the paper forward.
Adjusting the top-of-form position
The top-of-form position is the position on the page where the printer starts printing. If your printing appears too high or too low on the page, you can use the Micro Adjust feature to adjust the top-of-form position.

Advancing paper to the tear-off position automatically
To automatically advance your printed documents to the tear-off position, you need to turn on the Auto tear off mode and select the appropriate page length for continuous paper in Default Setting mode. For instructions, see Changing the Printers Default Settings on page 36. When Auto tear off is on, the printer automatically advances the paper to the tear-off position whenever it receives a full page of data or a form feed command followed by no more data.
Adjusting the tear-off position
If your papers perforation is not aligned with the tear-off edge, you can use the Micro Adjust feature to move the perforation to the tear-off position. Follow these steps to adjust the tear-off position: 1. Make sure the Tear Off (Font) lights are flashing (the paper is at the current tear-off position). You may need to press the Tear Off (Font) button to advance the paper to the tear-off position. Open the printer cover. Hold down the Pause button for about three seconds. The printer beeps and the Pause light begins to flash as the printer enters Micro Adjust mode. Press the LF/FF D button to feed the paper backward, or press the Load/Eject U button to feed the paper forward, until the paper perforation is aligned with the tear-off edge on the paper tension unit.

Tear-off edge

Note: The printer has a minimum and a maximum tear-off position. If you try to adjust the tear-off position beyond these limits, the printer beeps and stops moving the paper. 5. 6. After you set the tear-off position, press the Pause button to exit Micro Adjust mode. Tear off the printed pages.
When you resume printing, the printer automatically feeds the paper back to the top-of-form position and begins printing. Note: Your tear-off position setting remains in effect until you change it, even if you turn off the printer. (If you want to restore the printers default tear-off position, you can reset the printer. See page 37 for instructions.)
Printing on Single Sheets
You can load single sheets of paper one at a time using the printers paper guide. Before printing on single-sheet multipart forms, envelopes, or other special paper, make sure the paper thickness lever is set to the appropriate position. See Printing on Special Paper on page 29. Note: Load only one sheet at a time. To load a stack of single-sheet paper, use the optional cut-sheet feeder. See the Reference Guide for more information. You can use the paper guide to load single-sheet carbonless multipart forms that are fastened at the top by line gluing. Insert multipart forms in the paper guide, bound edge first and printable side down.

Follow these steps to load a single sheet: 1. If continuous paper is loaded in the push tractor, press the
Load/Eject button to feed it back to the standby position.
Push the paper release lever back to the single-sheet position and make sure the paper guide is in the upright position, as shown below.
Slide the left edge guide until it locks in place at the guide mark. Then adjust the right edge guide to match the width of your paper.
Insert a sheet of paper between the edge guides until it meets resistance. The printer automatically pulls it into the correct printing position. When the printer receives data, it begins printing. If the document is more than one page, the printer beeps three times after printing each page. Load the next sheet and the printer will continue printing.
Printing on Special Paper
With the LX-300+II, you can print on a wide variety of special paper types, including multipart forms, labels, and envelopes.
c Caution: on multipart forms, thicker-than-normal paper, labels, or When printing
envelopes, make sure your application software settings keep the printing entirely within the printable area. Printing past the edge of these papers can damage the print head.
Adjusting the paper thickness lever
Before printing on special paper, you need to make sure the paper thickness lever is set correctly for the type of paper youre using. Follow these steps: 1. 2. Turn off the printer. Lift up or remove the printer cover. The paper thickness lever is on the left side of the printer.
The numbers next to the lever indicate the thickness setting. Use the table below to select the appropriate paper thickness.
Paper type Standard paper (single sheets or continuous) Multipart forms 2-sheet 3-sheet 4-sheet 5-sheet Lever position 2 or 4

Labels Envelopes

Close the printer cover. Turn on the printer.

Multipart forms

You can use continuous or single-sheet carbonless multipart forms of up to five parts (one original plus four copies). Follow these guidelines: Set the paper thickness lever to the correct position for your forms. See page 29. Use continuous multipart forms that are joined only by spot gluing or side-crimping. Never load continuous multipart forms joined by metal staples, tape, or continuous gluing. Use single-sheet multipart forms that are line-glued only at the top. Insert the forms glued-edge-first into the printer. Make sure that multipart forms are not wrinkled. If you need to adjust the loading position, use your application software or change the loading position as described under Adjusting the top-of-form position on page 23. When you use side-crimped continuous multipart forms, the copies may not align with the original. If this happens, raise the paper guide.

For multipart forms, you should not print any closer than 0.5 inch (13 mm) from either side of the paper.

Labels

To print on labels, you must use continuous paper loaded on the pull tractor. Keep the following tips in mind: Set the paper thickness lever to the correct position for labels. (See page 29.) Choose labels mounted on a continuous backing sheet with sprocket holes designed for tractor use. Do not print labels as single sheets, because the shiny backing causes the paper to slip slightly. Load labels the same way you load ordinary continuous paper. See page 20 for loading instructions. Because labels are especially sensitive to temperature and humidity, use them only under normal operating conditions. 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 back of the printer; then press the LF/FF button to advance the remaining labels out of the printer.
c Caution: labels backward through the printer; they can easily peel off the Never feed
backing sheet and jam the printer.

Envelopes

You can feed envelopes individually using the paper guide. Keep the following tips in mind: Set the paper thickness lever to the proper position. See page 29. To load an envelope, follow the steps on page 27 for printing a single sheet. Insert the envelope printable-side down, wide-edge-first, between the edge guides. Push it firmly and hold it until it feeds into the printer. Use envelopes only under normal temperature and humidity conditions. Make sure the printing stays entirely within the printable area. The print head must not go past the left or right edge of the envelope or other thick paper. Its a good idea to print a test sample using a normal single sheet of paper before you print on envelopes.

8. Slide the left sprocket so its pins are aligned with the holes in the paper and push the blue lock lever to lock the sprocket in place. Then slide the right sprocket to match the width of your paper, but do not lock it. Move the paper supports midway between the two sprockets. When the printer receives data, it begins printing automatically. If you want to change the position where printing begins on the page, press the LF/FF button to advance the page to the next top-of-form position, and then see the next section to adjust the loading position. To eject the paper, tear off the paper entering the printer; then press the LF/FF button to feed the paper forward.
Adjusting the top-of-form position
If your printing appears too high or too low on the page, you can use the Micro Adjust feature to adjust the top-of-form position.
Never use the paper feed knob to adjust the top-ofform position; this may damage the printer or cause it to lose the top-of-form position.
9. 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 to remove any slack in the paper and then lock it in place.
1. Make sure the printer is turned on and paper is loaded. 2. Remove the printer cover. 3. Hold down the Pause button for about three seconds. The printer beeps and the Pause light starts flashing as the printer enters Micro Adjust mode. 4. Press the LF/FF D button to move the top-of-form position higher on the page, or press the Load/Eject U button to move the top-of-form position lower on the page.
Remove any remaining slack by gently pulling the paper from the back.
10. To separate the incoming paper from the printed paper, attach the paper guide. Hold it horizontally and fit its notches over the printers mounting posts. Then slide the paper guide toward the back of the printer until you feel it click. 11. Turn the paper feed knob to adjust the paper position. The perforation between pages should be just above the print head. 12. Replace the printer cover but leave it open. 13. Turn on the printer. 14. Set the Auto tear off feature in the Default Setting mode to Off; otherwise, the paper may jam. (See page 14 for more information.)
The printer has a minimum and a maximum topof-form position. If you try to adjust it beyond these limits, the printer beeps and stops moving the paper.

When the paper reaches the default top-of-form position, the printer beeps and stops moving the paper briefly. You can use the default position as a reference point when adjusting the top-of-form position. 5. After you set the top-of-form position, press the Pause button to exit the Micro Adjust mode.

10 - Epson LX-300+II

Your top-of-form position setting remains in effect until you change it, even if you turn off the printer.
The top margin setting made in some software applications overrides the top-of-form position setting you make with the Micro Adjust feature. If necessary, adjust the top-of-form position in your software.
Adjusting the tear-off position
If your papers perforation is not aligned with the tear-off edge, you can use the Micro Adjust feature to move the perforation to the tear-off position. Follow these steps to adjust the tear-off position: 1. Make sure the Tear Off (Font) lights are flashing (the paper is at the current tear-off position). You may need to press the Tear Off (Font) button to advance the paper to the tear-off position. 2. Open the printer cover. 3. Hold down the Pause button for about three seconds. The printer beeps and the Pause light begins to flash as the printer enters Micro Adjust mode. 4. Press the LF/FF D button to feed the paper backward, or press the Load/Eject U button to feed the paper forward, until the paper perforation is aligned with the tear-off edge on the paper tension unit.

Tear-off edge

If you want to restore the printers default top-of-form position, you can reset the printer. See Restoring the printers default settings on page 14 for instructions.
Advancing paper to the tear-off edge
When the push tractor is installed, you can use the tear-off feature to advance your continuous paper to the printers tearoff edge when you finish printing. You can then easily tear off the printed document. When you resume printing, the printer automatically feeds the paper back to the top-of-form position; so you can save the paper normally lost between documents. You can use the tear-off feature in two ways:
Manually, by pressing the printers Tear Off (Font) button Automatically, by turning on the Auto tear off function in

Default Setting mode.

Using the Tear Off button
After the printer finishes printing your document, check that the Tear Off (Font) lights are not flashing. Then press the Tear Off (Font) button. The printer advances the paper to the tear-off edge.
If the Tear Off (Font) lights are flashing, the paper is in the tear-off position. If you press the Tear Off (Font) button again, the printer feeds your paper to the next top-of-form position.

Never feed labels backward through the printer; they can easily peel off the backing sheet and jam the printer.

Clearing a Paper Jam
If paper becomes jammed in the printer, follow these steps to remove it: 1. Turn off the printer, open (or remove) the printer cover, and remove the paper guide. 2. If continuous paper is jammed in the printer, tear off the fresh supply at the perforation nearest the paper entry slot. 3. Gently remove any paper inside the printer, including any torn pieces. You can use the knob on the right side of the printer to help feed the paper out.
Use the paper feed knob to clear paper jams only when the printer is off. Otherwise, you may damage the printer or change the top-of-form or tear-off position.

Printing a Self Test

If you are having printing problems, you can run the printers self test to help you determine whether the printer or the computer is causing the problem. If the self test results are satisfactory, the printer is working properly and the problem may be caused by your printer driver settings, application settings, computer, or interface cable. (Be sure to use a shielded interface cable.) If the self test does not print properly, there is a problem with the printer. See the Reference Guide for possible solutions to the problem. You can print the self test using either single sheets or continuous paper. Use paper that is at least 8.25 inches (210 mm) wide. 1. Make sure paper is loaded and the printer is turned off. 2. To run the test using a draft font, turn on the printer while holding down the LF/FF button. To run the test using the printers near letter-quality font, hold down the Load/Eject button while you turn on the printer. (Either self test can help you determine the source of your printing problem, but the draft self test prints faster.) After a few seconds, the printer begins printing the self test (a series of characters).
To temporarily stop the self test, press the Pause button. To resume, press it again.
4. Replace the printer cover and paper guide, and turn on the printer. Make sure the Paper Out light is not flashing and the Pause light is off.

Bidirectional Alignment

If you notice that the vertical lines in your printout are not properly aligned, you can use the printers bidirectional adjustment mode to correct this problem.
To complete the steps below, you need 5 letter or A-4 size single sheets or 5 pages of continuous paper. If you use single sheets, you need to load a new sheet of paper each time the printer ejects a printed sheet onto the paper guide.
3.To end the self test, press the Pause button to stop printing. If paper remains in the printer, press the LF/FF button to eject the printed page. Then turn off the printer.
Do not turn off the printer while it is printing the self test. Always press the Pause button to stop printing and the LF/FF button to eject the printed page before you turn off the printer.
1. Make sure paper is loaded and the printer is turned off.
Whenever you turn off the printer, wait at least 5 seconds before turning it back on; otherwise you may damage the printer.
2. While holding down the Pause button, turn on the printer. It enters the bidirectional adjustment mode, then prints instructions and the first set of alignment patterns. 3. As described in the instructions, compare the alignment patterns and select the pattern with the best alignment. 4. Follow the instructions to print the remaining sets of alignment patterns and select the pattern with the best alignment in each set. 5. After you select the best pattern in the final set of alignment patterns, turn off the printer and exit the bidirectional adjustment mode. Your selections are saved automatically.

Cleaning the Printer

To keep your printer operating at its best, you should clean it thoroughly several times a year. Follow these steps: 1. Remove any paper loaded in the printer and turn it off. 2. Unplug the power cord from the electrical outlet; then disconnect the interface cable from the printer. 3. Remove the paper guide. If a pull tractor or an optional cutsheet feeder is installed, remove it. 4. Use a soft brush to carefully brush away all dust and dirt from the outer case and paper guide.

Epson LX-300+II - 15

5. If the outer case or paper guide is still dirty, clean it with a soft, clean cloth dampened with mild detergent dissolved in water. Keep the printer cover in place and flat on top of the printer to prevent water from getting inside the printer.
Never use alcohols or thinners to clean the printer; these chemicals can damage the printer components as well as the case. Be careful not to get water on the printer mechanism or electronic components. Do not use a hard or abrasive brush. Do not spray lubricants inside the printer; unsuitable lubricants can damage the printer mechanism.
