Running the Self Test The self test prints out the settings of the printer's DIP switches and the characters in the printer's memory. The test can be run in either high-speed draft, normal draft, or Letter Quality (LQ) mode. You select the draft mode or Letter Quality mode, depending on which button you hold down as you turn on the printer. You choose between the high-speed draft and the normal draft mode by changing your printer's DIP switch settings. Your printers default setting is high-speed draft mode. To run the test in normal draft mode, see Setting the DIP Switches in Chapter 3 before following the steps below. The self test is 8 inches wide on the LQ-850,11 inches wide on the LQ-950, and 14 inches wide on the LQ-1050. 0I. CAUTION: Never run the self test using paper that is narrower than 8.27 inches (210 mm) on the LQ-850,11 inches (279 mm) on the LQ-950, or 14 inches (360 mm) on the LQ-1050. This prevents the print head from printing directly onto the platen, which can damage the print head. Although the self test can be run with continuous paper, use singlesheet paper now because single-sheet loading is easier. Be sure to use paper that is wide enough for the self test to print. If you need to load continuous paper to print the self test, see Loading Continuous Paper in Chapter 3. 1. Make sure the printer is turned off. Setting Up the Printer 1-19
