Check the page length set by your application software and adjust it if necessary.

If you are using the cut sheet feeder, the self test function prints the number of printable lines that can fit on a single sheet. Use this feature to determine the correct page length setting. See Chapter 3.

One-inch skip over perforation may be set. Set DIP switch 2-3 to off.

The loading position of the paper may be too high or too low. Use the microadjustment feature to reset the loading position so that the perforation is centered within the skip area.

Your application program may be setting the top and bottom margins. If this is the case, turn off skip over perforation by setting DIP switch 2-3 to off.

7-12 Troubleshooting

Printing

Problem

The print position is not what you expected

(continued).

Vertical printed lines do not align or gaps appear in lines or graphics.

Solution

The printer is usually set for bidirectional printing. This can cause a slight misalignment of graphics characters.

When precise printing of vertical lines is necessary, contact your service center to have them perform the bidirectional print alignment adjustment or select the unidirectional print mode by sending

ESC U or ESC < to the printer. You can also select unidirectional printing by setting DIP switch 2-6 to off.

Unidirectional printing is slightly slower.

See Chapter 9.

Note: Use the data dump mode to check data being sent from the computer. In the data dump mode, data is printed in hexadecimal format and in ASCII characters. See Data Dump

Mode in Chapter 3.

If the printer still does not print, try the self test described in

Chapter 1. If the self test works properly, the printer is all right, and the problem probably lies in the computer, the software, or the cable. If the self test does not work, contact your Epson dealer.

The paper supply may be obstructed by a cable or some other object. Make sure that the paper feeds smoothly into the printer.

See Chapter 2.

Your supply of continuous paper may be too far from the printer. Position your paper supply within 3 feet (1 meter) of the printer. See Chapter 2.

The paper may be caught on the edge guides. When using continuous paper, make sure that the paper guide is lowered to the horizontal position and that the edge guides are positioned as far apart as possible. See Chapter 2.

The holes on the sides of the paper may not be aligned with each other. Reposition the paper on the tractor pins. See Chapter 2.

The sprocket units are incorrectly positioned for the paper width. Move the right sprocket unit to remove any slack across the width of the paper. See Chapter 2.

The position of your paper supply may be preventing it from feeding straight. See

Chapter 2.

7-18 Troubleshooting

Paper Handling

Problem

Continuous paper does not feed properly

(continued).

The paper feed is crooked or the paper jams (continued).

Regular gaps occur in the printout.

Solution

The sprocket lock levers may be unlocked, or the sprocket covers may be open. Position the sprocket units to match the width of your paper. Then, lock them in place by pressing the sprocket lock levers away from you. See Chapter 2.

The paper guide may be in the upright position. When using continuous paper, make sure that the paper guide is in the lowered position so that it can act as a paper separator. See Chapter 2.

The paper thickness lever may be in the wrong position. For printing on ordinary paper, always set the lever to position 2.

The paper dimensions may exceed the specified limitations. Use only paper sizes that are within the specified range. Your printer can print on continuous multi-part forms consisting of 1 original and 1 or 2 copies. See Chapter 8.

Skip over perforation may be interfering with your application program settings.

Paper Handling

Problem

Continuous paper does not feed properly

(continued).

Skip over perforation is set, but the perforation does not fall in the center of the skip.

The loading position of the paper shifts slightly while printing several pages.

Solution

The loading position of the paper may be too high or too low. Use the microadjustment to reset the loading position.

After printing stops, the paper automatically feeds forward.

The short fear-off function is selected

(DIP switch 2-2 is on), but it does not work.

The paper you are trying to feed may be too heavy for the built-in push tractor.

When highly accurate paper feed is necessary, such as when printing carbon copies, use the optional pull tractor.

The short tear-off function may be selected. When you resume printing, the paper feeds backward to its loading position. If you do not need this function, set DIP switch 2-2 to off. See Chapter 3.

There may still be data in the print buffer.

The short tear-off function works only if the data in the print buffer is completely printed and the next print position is at the top of the next page.

Your program may not be sending a form feed command to the printer. At the end of your program or the page, send a form feed (FF). If you are using BASIC, be sure to add a semicolon (;) after the FF code to prevent any additional codes from being sent to the printer.
