If paper is not loaded, the printer attempts to load it. 3. If the printer camot load paper, it indicates this by turning on the PAUSE light. In this case, insert paper again and press the LF/FF button. 4. The printer prints alphanumeric characters continuously. 5. Quit self-test mode printing by pressing the PAUSE button and turning the printer off. 1-14 Rev.

This section describes how to run a hex dump. Turn on the printer while holding down the LF/FF and FONT buttons. 2. If paper is not loaded, the printer attempts it (either single sheet or continuous paper). 3. If the printer cannot load the paper, it indi~tes a paper-out error. In this case, insert paper again, and press the PAUSE button. 4. The printer waits for data after printing the message "Hex dump." 5. Received data is printed as both hexadecimal codes and ASCII characters. If a corresponding printable character does not exist, the printer outputs a period (.). 6. Quit hexadecimzd dump printing by pressing the PAUSE button and tumingtheprinter off. 1. Note: In hex dump mode, the character table depends on the default settin& and 10 cpi draft is selected automatically. 1.4.4 Printer Status Indication It describes how this printer indicates status and error conditions using LEDs and the beeper.

If the printer state is not one of the conditions shown below, this operation is ignored. . TOF position adjustment: The position mn be adjusted just after the paper is loaded. . Tear-off position adjustment: The position can be adjusted when paper is actually located at the tear-off position. In the adjustment mode, press the LF/FF button to feed paper forward and the FONT button to feed paper backward. You can cancel adjustment mode bypressingthe PAUSE button or inputting a print command. The adjusted position is stored in non-volatile memory. Rev. A 1-15 Product Description LXiWO Service Manual 1.4.7 Printer Initialization There are two types of initialization: hardware initialization and software initialization. 1.4.7.1 Hardware Initialization Hardware initialization is performed by: . Turning on the printer. . Sendiny@e parallel interface the~signal. (If the INIT signal is active when the printer is turned on, hardware initialization is started when the ~ signal becomes imctive.) When hardware initialization is performed: . The printer mechanism is initialized. . Print data in the input buffer is cleared. . Download character definitions are cleared. . The printer's settings are returned to the defaults. . The printer is set to the standby condition, if no fatal error occurs. . Continuous paper home-seeking is performed. In continuous paper home-seeking: . The printer feeds continuous paper to the paper park position. q The printer then loads the paper again. q If ejection to the paper park position cannot be completed within 16 inches, paper is returned to its previous position. 1.4.7.2 Software Initialization Software initialization is performed upon receipt of the control code ESC C?. When software initialization is performed: . Print characters in the buffer are not cleared. . The printer setting is changed to the default, but the download character definition is not cleared. 1.4.8 Printer Settings 1.4.8.1 Selectable Printer Settings The following printer settings can be changed by users in default-setting mode: Character spacing: Shape of zero: Auto line feed: Character table (Standard): Character table (NLSP): .lQc@ / 12cpi Slashed / Not slashed on/Qff Italic (JJSA/France/Germany/UK/Denmark l/Sweden/Italy/ Spain 1)/PC437/850/860 /861/863 /865/BRASCII/Abicomp Italic &?SA/France/German y/UK/Denmar k l/Sweden/Italy/ Spain 1)/KG7/~/S2/8S/E5 /857/=/869/07 Greek/ISO Latin IT /1S0 8859-7/Code MJK/Mazowia/Bulgaria 11/ 12/ 8.5 / 70/6 inches on/Qff Single / Double ~/ Auto selection (30 sec wait) / Parallel / Serial 300 / 600/ 12(MI / 2400 / 4800 / $?6Ul / 19200 bps Mm/ Odd / Even Z.Ms / 8 bits ~ / Enabled ... ~? ..... 1 inch skip-over-perforation: on/Qff Page length: Auto tear off: Tractor: interface: Bit rate (serial I/F): Parity bit (serial I/F): Data length (serial I/F): ETX/ACK (serial I/F): Note: 1-16 Underlines show factory setting. Rev. A LX-300 Service Manual Product Description 1.4.8.2 Changing the Default Settings You can change some parameters that the printer refers to at printer initialization. 1. To enter the default setting mode, turn on the printer while holding down the FONT button. The printer prints out the firmware version. If paper is not loaded, insert a sheet of paper. 2. The printer automatically loads the paper and prints a table of languages to choose from: English, French, German, Italian, and Spanish. The Footlights indicate the currently selected language, as shown in the table below. Table 1-18.
