1. CONTROL PANEL 1-1. Basic Operation POWER ALARM 3 4 5 ON LINE 1 FEED 2 Fig. 1-1 Control panel 1 “ON LINE” switch Switches the printer between “ON LINE” and “OFF LINE”. Whenever the printer switches between “ON LINE” and “OFF LINE”, the buzzer gives one short beep (“ON LINE” and “OFF LINE”, switching is possible only when the paper is loaded in the printer.) 2 “FEED” switch • When this switch is pressed and then released within 0.5 sec.,the paper feeds one line.
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 character order.
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 ON LINE switch.
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 alignment by 1/2-dot increments. The adjustment procedure is explained on the following pages.
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 current setting.
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.

2-4. Interface Connections The following is a basic example of interface connections. (For interface connections, refer to the specifications for the respective interface.) IBM PC type serial port is shown as example.
2-5. 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.
2-6. Data Structure 2-6-1. DTR mode This mode is accessed when the DIP switch 3-5 is ON. Signals are controlled using the DTR line as BUSY flag. Data RXD Data Buffer full Data Buffer empty DTR Printing Power ON When paper is out RXD OFF LINE ON LINE DTR Printing Paper out Press the ON LINE switch after loading paper. PAPER OUT signal Power ON If a printer errors do not occur after the power is turned on, the DTR signal line changes to “SPACE”.
Data buffer Full Near Empty Near Full Remainder 256 bytes Empty 256 bytes DTR “MARK” DTR “SPACE” [Paper out] When the “paper out’ detector senses the end of the paper, the printer stops printing after printing a maximum of two more lines or on feeding the paper. Immediately after a “paper out” condition is detected, the printer sets to OFF LINE and the DTR changes to “MARK”. (To reset printer after a “paper out’, load paper into the printer and press the ON LINE switch to set the printer to ON LINE.
[Framing error] A framing error occurs when SPACE is detected at the stop bit. When a framing error or a vertical parity error occurs for the data which is received, the printer prints out a “?” mark to indicate that the error occurred. [Compulsion switch] When pin 6 of the peripheral unit drive circuit connector is set “HIGH”, status bit 7 becomes “1”. 2-6-2. X-ON/X-OFF mode This mode accessed when the DIP switch 3-5 is OFF.
Data buffer Full Near Empty Near Full Remainder 256 bytes Empty 256 bytes X-OFF X-ON [Paper out] When the “paper out” detector senses the end of the paper, the printer stops printing after printing a maximum of two more lines or on feeding the paper. The printer will set the DTR to “MARK” and set the printer to OFF LINE five seconds after a “paper out” condition is detected.

When a framing error or a vertical parity error occurs for the data which is received, the printer prints out a “?” mark to indicate that the error occurred.
2-6-3. STX-ETX mode This mode is accessed from whichever DTR mode or X-ON/X-OFF mode. To set this mode, the data buffer must be empty. The host computer sends an ENQ code to the printer and acknowledges the printer status. Then, the host computer checks if the printer buffer is empty. After the host computer detects that the buffer is empty, a STX code and data are transmitted.
[Compulsion switch] When pin 6 of the peripheral unit drive circuit connector is set at “HIGH”, status bit 7 becomes “1”.

FUNCTION Immediate drive command for peripheral unit 2 CODE (19)H OUTLINE Dives peripheral unit 2. Pulse width is fixed at 200 ms with a fixed delay time of 200 ms.
FUNCTION Set deselect mode CODE (13)H OUTLINE (1) When using serial interface printer: This function differs depending on the setting of DIP switch 4. a) When the DC1, DC3 invalid mode is set (DIP switches 4-1 to 4-4 are all set to ON), the printer ignores this code. b) In the DC1, DC3 valid mode (with DIP switches 4-1 to 4-4 set to OFF), data following this code is ignored when the printer receives a code. The deselect mode is canceled by code.
c) If the printer receives a n code (n is the DIP switch controlled address) during the addressable mode (with DIP switches 4-1 to 4-4 set other than settings a) and b) above,), the deselect mode is canceled and data following this code is input to the buffer. Note that addressable mode is valid only when optional RS-422A interface is installed.
FUNCTION Enquiry CODE (05)H OUTLINE This code is valid when using serial interface printer. Online in STX-ETX mode: The printer sends the status data and the check byte to the host computer. Online in any other mode: The printer sends only the status data to the host computer. Offline in any mode: The printer only sends the status data to the host computer if there is a mechanical error in the status bit, or if the paper out or power down bit is set.
