1. CONTROL PANEL 1-1. Basic Operation 1 “ON LINE” switch Switches the printer between “ON POWER 3 LINE” and “OFF LINE”. When- ALARM ever the printer switches between 4 “ON LINE” and “OFF LINE”, the 5 buzzer gives one short beep (“ON ON LINE LINE” and “OFF LINE”, switching 1 is possible only when the paper is loaded in the printer.) FEED 2 “FEED” switch 2 • When this switch is pressed and then released within 0.5 sec.,the paper feeds one line. Fig. 1-1 Control panel • When this switch is depresse

1-2. Switch Operation (Combined Switch Operation) 1 FEED + POWER ON (Turn the power on while holding the FEED switch depressed.) Self-printing will be performed according to the VER. NO., DIP switch settings and character order. When the FEED switch is held continuously during self printing, only the characters will print out repeatedly. In models with cutter, cutting will be done after self-printing is performed according to the VER. NO., DIP switch setting and charact

2 ON LINE + POWER ON (Turn the power on while holding the ON LINE switch depressed.) Each of the signals sent from the computer to the printer will be printed out in hexadecimal code. This function allows you to check if a control code sent to the printer by the program being used is correct or not. The buzzer will sound once to indicate the printer is in hexadecimal dump mode. After the program has been run, the last line buffer should be flushed by pressing the

5 (Sprocket-type Only) ON LINE + FEED (Press the FEED button while holding the ON LINE button depressed when the printer is ON LINE) The buzzer gives three short beeps and the printer sets the page top. 6 (Twin Head Only) FEED + ON LINE + POWER ON This mode enables adjustment of the forward and backward printed line align- ment by 1/2-dot increments. The adjustment procedure is explained on the following pages. – 4 –

1. Enter the Dot Alignment Adjust Mode by turning on the power while pressing the ONLINE and FEED switches. 2. When Dot Alignment Adjust Mode starts, the buzzer will sound twice and “Dot Alignment Adjust Mode” is printed. 3. Seven dot alignment patterns are printed as shown below. The patterns are arranged with the backward printed lines more toward the left as the patterns are printed down the page; the fourth pattern is the standard. The asterisk (*) indicates the pattern printed with the curr

4. To choose a pattern with a closer alignment of the forward and backward printed lines, count from the top down to the desired pattern and press the FEED switch the counted number of times. (The buzzer sounds each time the FEED switch is pressed, up to a maximum of seven times. However, if the FEED switch is pressed more than seven times, a warning sounds.) 5. Press the ONLINE switch after the setting is made. (If the power is turned off before the ONLINE switch is pressed, the new setting bec

Installing the Optional Interface Board When using the optional 20 mA current loop interface or the RS-422A interface, the optional interface board must be mounted to the printer’s main logic board. The following is the method of mounting the interface board to the printer’s main logic board. 1 Remove the 6 screws on the bottom cover of the printer, then remove the bottom cover. 2 Connect the optional interface board connector to connector CN9 on the printer’s main logic board. 3 At the sam
