Operating the Control Panel Other control panel features The control panel of your printer also gives you access to several special functions. Self test: Both a draft and Letter Quality self test function are built into the printer. The self test printout lets you check the current DIP switch settings and operating status of the printer. You can start the printer's self test by holding down the LINE FEED button or the FORM FEED button while turning on the printer. See the section on the self test in Chapter 1 for more information. Micro-adjustment: By pressing the FORM FEED button immediately after loading paper or when using short tear-off, you can make fine adjustments to the loading and short tear-off positions. These positions can only be adjusted while the MULTI-PART light is blinking. See the sections on adjusting the loading position and using the short tear-off function later in this chapter. Data dump: By holding down both the LINE FEED and FORM FEED buttons while you switch on the printer, you turn on the data dump mode. This feature allows advanced users to locate the source of communications problems between the computer and printer. See the section on using the data dump mode on page 3-24 for more information.
