Removal of Ink Ribbon Hold the spool and lift gently, rotating it until the ribbon sags. Push the ribbon detecting lever out, lift the spool until it comes off the shaft. Remove the second spool in a similar manner. (Do not apply excessive force when lifting spools.
4-3. Paper Insertion 4-3-1. For Roll Paper (1) (2) (3) (4) Cut the Roll Paper end straight and square. Hold the roll so that the paper comes from the bottom. Attach the Roll Paper to the Holders Paper by slipping one side of the roll onto the Hub and pulling the other Hub out to allow the roll to slip in place. Insert the paper evenly into the Paper Insertion Slot. Turn the Power Switch “ON”, and press the FEED Button. The paper will be fed into the unit. Figure 4-4. Paper Insertion (1) Figure 4-5.
4-3-2. Roll Paper Installation (When using the optional Printer Cover 8340R) When installing roll paper with the optional “Ptinter Cover 8340R”, please use the following procedure. (1) Turn power off, lift the Printer Cover up and remove it. Note: Be careful not to touch the print head immediately after printing because it can get very hot. (2) Insert paper into the printer, and feed the paper so it extends 3 inches or more above the top surface of the printer.
4-3-3. Validation Option Installation The validation printing requires the optional printer cover 8340R. Refer to item 4-3-2 for the installation. (1) Turn power ON. (2) Enter the printer the validation mode. (Refer to the control code “GS” in Chapter 5.) (3) Insert the material to be validated against the right side of the slot in the Printer Cover 8340R. Figure 4-8. Insertion of Material to be validated 4-4.
5. CONTROL CODES CODE FUNCTION LF (0A)H Print and line feed instruction OUTLINE The LF code causes the data in the line buffer to be printed, followed by a single line feed. When the line buffer is empty, only the feed takes place. CODE CR (0D)H Print and line feed instruction FUNCTION OUTLINE Same function as of LF code. However, when the DIP switch 2-4 is ON, the CR code becomes invalid.
CODE FUNCTION SI (0F)H Inverted print instruction OUTLINE This function causes the printing to be inverted. This code must be received at the beginning of a line. If this code is received anywhere other than at the beginning of a line, it is disregarded. Accordingly, normal characters and inverted characters, can not be mixed on the same line. CODE DC2 (12)H Release from inverted print instruction FUNCTION OUTLINE The inverted print instruction is released by this code.
CODE FUNCTION ESC a n (1B)H (61)H n n-line feed OUTLINE After printing the data in the current line, n lines are fed by this code. The value of n ranges from 1 to 120. CODE ESC C n (1B)H (43)H n Sets page length in lines FUNCTION OUTLINE This code sets the length of a page to n lines. The value of n ranges from 1 to 120. On initialization, the page length default condition will be 42 lines. The line feed pitch is onesixth inch.
CODE FUNCTION ESC @ (1B)H (40)H Printer initialization OUTLINE All printing conditions except ESC BEL n1 n2, the line buffer and data buffer are set to the power on default condition. CODE ESC BEL n1 n2 (1B)H (07)H n1 n2 Sets peripheral unit drive pulse duration. FUNCTION OUTLINE This command sets the pulse duration for peripheral unit drive (Paper Cutter, Take-Up Device, cash drawer, etc.
FUNCTION FS (1C)H Trigger peripheral unit drive (immediate) OUTLINE Causes a peripheral drive pulse to be generated immediately CODE ENQ (05)H Enquiry CODE FUNCTION OUTLINE When this code is received, the printer outputs status data. If it is input after text data input in the STX-ETX mode, the printer outputs status data and the check byte. CODE STX (02)H Start of text FUNCTION OUTLINE When this code is received, the printer enters the STX-ETX mode.
CODE FUNCTION ESC M (1B)H (4D)H Select 15 CPI OUTLINE This code causes the printer to print at 15 CPI. The number of columns per line is 44. When the power is turned on, the 15 CPI mode is selected. CODE GS (1D)H Validation printing instruction FUNCTION OUTLINE REMARKS This code causes the printer to perform validation printing of a maximum of 32 subsequent characters (at 15 CPI, from the thirteenth to the forty-forth column).

Figure 8-5. D-Sub 25 Pin Connector *1 Error Condition Alarm Mode If an error condition is detected during operation, the printer will stop printing and cause the FAULT signal to go MARK. All solenoides & motors TYPE will be de-energized. It is necessary to turn the printer power off and on again ONLY in order to recover from the alarm mode. This printer can detect the following error coditions: a. Motor Lock b. Defective timing detector c. Micro-proccessor out of program sequence D 8-6.
8-7. Peripheral Unit Drive Circuit The Control Board of this unit is equipped with a circuit for driving a peripheral unit (Paper Cutter, Take-Up Device, Cash Drawer, etc.) The Control Board Connector (CN3) is used to connect the Peripheral Unit to the Drive Circuit. When using this circuit connect the peripheral unit cable to the CN3 Connector (cable is not included). Use a cable with the following specifications: Note: Do not run cable near devices generating large amounts of electrical noise.

Refer to the Control Codes in Chapter 5.
9. DATA STRUCTURE AND CONTROL 9-1. DTR Mode (1 BLOCK) Controls Data Transfer by using DTR line as BUSY FLAG (a) (b) In case of Paper Empty Paper Empty When the paper out detector indicates end of paper, the printer stops printing after a maximum of two lines of printing or paper feed. The printer goes OFF LINE and sets the DTR to “MARK” status immediately after occurrence of a paper empty.
9-2. X-ON/X-OFF Mode The printer transmits an X-ON (Control Code; DC1, Hexadecimal Value; 11H,) signal after power is turned on, if there is no printer error being generated. When this signal is received by the host computer, the host computer transmits the data to the printer. The X-ON signal is output intermittently every three seconds until the host computer receives and responds to this signal.
Paper Empty When the paper out detector indicates end of paper, the printer stops printing after a maximum of two lines of printing or paper feed. The host computer can receive the printer status by transmitting an ENQ code to the printer. The printer goes OFF LINE and sets the DTR to “MARK” status in 5 seconds after occurrence of a paper empty. It is necessary to install paper into the printer and press the ON LINE BUTTON to light the ON LINE LAMP in order to recover from paper empty status.
9-3. STX-ETX Mode The start of the STX-ETX mode should occur with a totally empty print buffer. This can be achieved by sending an ENQ code to the printer and checking the status until the status code indicates an empty buffer. At that point, the STX code is sent by the host computer followed by a data block. While receiving the data block, the printer generates a horizontal parity check character.

11. WHEN POWER IS SUPPLIED BY THE USER When printer power is supplied by the user rather than through the accessory power source unit, please be careful of the following points. Note 1: The power supply must be +12V +10% –5% 2A or above. An electrolytic capacitor (C = 4700µF/25V to 6800µF/25V) must be connected across the output of the power supply. Note 2: A DC power plug is available as an option. GND +12V GND Reference: Design the power supply referring to the power supply circuit shown below.
VAC 14V C2 100 ~ 200µF/25V VDC 12V +10% –5% ZD1 VZD = 14V (1W) IAC C1 2 ~ 3A 6800µF/25V C3 TR1 4700 ~ 6800µF/25V 2SD633 (TOSHIBA) Other parameters may be determined by user. Figure 11-1.
