Self test: Hold down the LF/FF button (for LQ printing) or the LOAD/EJECT button (for draft printing) while turning on the printer. The self test lets you

check that your printer is operating properly. Hold down the ALT button while turning on the printer to print out a list of the current DIP-switch settings.

See the section on testing the printer in Chapter 1 for more information.

Data dump: Hold down the LF/FF and LOAD/EJECT buttons while turning on the printer to enter data dump mode. Data dump mode allows advanced users to find the cause of communication problems between the printer and the computer.

The data dump mode is more fully explained at the end of this chapter.
