1. OUTLINE The DP8340R series of serial dot matrix printers is for use in eCR, POS, elec- tronic instruments, banking machines and computer peripheral equipment. The DP8340R series include the following features; 1) 2 color printing (Red and Black) 2) High-speed bidirectional printing (2 line/sec, 29 or 44 columns per line) 3) 9-pin print head 4) the interface conforms to RS-232C in M type, and to RS-232C/20ma Current loop in D type. 5) Commands for expanded characters, inverted characters, emphasized characters, red and black printing, and 10CPI or 15CPI characters etc. are provided, which makes the printer very versatile.
2-2. Installation of Paper Holders and Re-Roll Prevention Guard Install the Paper Holders in the intermost holes in the rear of the printer. Figure 2-2. Installation of Paper Holders Install the Re-Roll Prevention Wire in the holes of the printer cover. twisting the Wire as shown in the figure below, will make the installation easier. Figure 2-3.

2-3. Handling Care 1. Be careful not to drop paper clips, pins or other foreign matter into the unit as these cause the printer to malfunction. 2. do not attempt to print when either paper or ribbon cartridge is not located in the printer, otherwise the print head can be damaged. 3.
2-4. Maintenance Essentially, your printer is a robust piece of equipment, but should be treated with a modicum of care in order to avoid malfunctions. For example: 1. keep your printer in a “comfortable” environment. Roughly speaking, if you feel comfortable, then the environment is suitable for your printer. 2.

4. INsTaLLaTION Of INk rIbbON aNd papEr 4-1. Installation of Ink Ribbon (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. Figure 4-1. Printer Cover Removal (2) Unwind ribbon so that the spools are separated as shown in Figure 4-3. Hold the ribbon taut as shown with the drive pins facing down and slide the ribbon between the print head and the platen. While keeping the ribbon taut, wrap one side around the black ribbon guide on the end of the platen and drop one spool on the spool shaft. as you move the spool downwards, move the detecting lever aside to allow the spool to drop into place. Make sure the spool drive pins engage with the spool drive holes. as the spool drops into place there will be a click.

9. daTa sTrUcTUrE aNd cONTrOL 9-1. DTR Mode (1 BLOCK) Controls Data transfer by using DtR line as BUSY FlaG (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. 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. Machine Error a machine error may be generated by paper jamming or when the printer is unable to print data. When a machine error occurs the printer stops printing. The printer goes OFF lINe and sets the DtR to “MaRk” status immediately after the occur- rence of Machine error. It is necessary to turn the printer power off and on again in order to recover from Machine error. – 33 –...
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. The X-OFF (DC3, 13H) signal outputting begins when the amount of empty space in the buffer becomes less than 256 bytes. When the computer receives the X-OFF signal, it will halt data transmission as soon as it can. However even at this time the printer can receive data until the buffer is completely full. an X-ON signal is output when the contents of the buffer goes below 256 bytes. The increase of the empty area in the buffer is caused by printing. If the computer causes a buffer over- flow, a flag bit in the status register will be set. (See Status) The X-OFF signal will continue to be output at a 3-second interval until the data...

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 occur- rence 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. after the data block is sent, the host computer sends an eNQ which causes the printer to return 2 characters, one would be the normal status character, and the second would be the horizontal parity check character that was generated by the printer while the data block was received. The host computer checks the status character to determine if any vertical par- ity errors or other errors occurred during block transmission, and checks the horizontal parity character against a character generated in the host computer while the data was transmitted. If there are no errors, etX causes the buffer to...
11. WhEN pOWEr Is sUppLIEd by ThE UsEr Note : The optional AC adapter (PS8340A) has been designed specifically for this unit(DP8340). Other AC adapters may not meet the EMC technical standards. 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: An electrolytic capacitor (C = 4700µF/25V to 6800µF/25V) must be connected across the output of the power supply. Use a power supply of DC 12 V ± 5% and more than 2.0 A with SELV output and LPS or Class 2 (double-insulation structure) output approved by IEC60950.
