EPSON LQ-680Pro 6. When you finish, turn off the printer to exit the default setting mode. The current settings remain in effect until you change them again. Bidirectional Alignment If you notice that the vertical lines in your printout are not properly aligned, you can use the printer's bidirectional adjustment mode to correct this problem. To complete the steps below, you need 5 single sheets or 5 pages of continuous paper that are at least 11 inches (279 mm) long and 9.5 inches (241 mm) wide. If you use single sheets without a cut-sheet feeder, you need to load a new sheet of paper each time the printer ejects a printed sheet onto the paper guide. 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. Printing a Self Test Running the self test helps you determine whether the printer or the computer is causing a printing problem. You can print the self test using either single sheets or continuous paper. 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. Either self test can help you determine the source of your printing problem; however, the draft test prints faster than the letter-quality test. After a few seconds, the printer loads the paper automatically and begins printing the self test. A series of characters is printed. To temporarily stop the self test, press the Pause button. To resume the test, press the Pause button again. 3. To end the self test, press the Pause button to stop printing. Then turn off the printer. If the self test results are satisfactory, the printer is working properly and the problem probably results from 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. Printing a Hex Dump If you are an experienced user or a programmer, you can print a hexadecimal dump to isolate communication problems between the printer and your software program. In hex dump mode, the printer prints all data received from the computer as hexadecimal values. You can print a hex dump using either single sheets or continuous paper. Use continuous paper that is at least 9.5 inches (241 mm) wide (or A4 or letter-size single sheets). 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. To enter hex dump mode, hold down both the LF/FF and Load/Eject buttons while you turn on the printer. 3. Open a software application and send a print job to the printer. Your printer prints all the codes it receives in hexadecimal format. 2. To run the test using the Draft font, hold down the LF/FF button while you turn on the printer. To run the test using the printer's letter-quality fonts, hold down the Load/Eject button while you turn on the printer. 11/00 EPSON LQ-680Pro - 15
