The met 1. 2. NOTICE FOR THE PRINTER USED IN EUROPE cable of the interface (parallel port or serial port) for printers must be prepared by the user and must be the following specifications : Use the shielded cable for the connection to the printer . Use the noise filter on the cable and the cable should be turned as shown in following Figure . Noise filter ( Ferrite-ring enclosed to printer package ) Figure : The noise älter is r quired for the connection to the parallel port or serial port .
The Notice For Watch-Dog Function in DPN-833/8233/8333 Printer The Watch-Dog function has been added in DPN-833, DPN-8233 and DPN-8333 p rinters . lt will improve the anti-interference of the printers greatly . When the printer is in abnormal state due to some interference such as ESD, Burst or RF in long time exceeding the period of the watch-dog timer, the printer will be restarted automatically as well as the printer resets while power on .

2 .2 Accessories Examination .A paper roll and a ribbon cassette have been loaded inside the printer before packing. A user's manual is included. The user may select optional accessories according to their needs (see Appendix F) . 1 . Push forward the removable Cover Plate with both thumbs . (Note the arrow on Cover Plate. See Figure 2-2 and Figure 2-3 .) Then take off Cover Plate carefully . 2 .
2 . Hold the left end of the ribbon cassette with your left hand . Hold right end in right hand . Right thumb is on top and forefmger below (Figure 2-4) . Lift the right end ofthe cassette with the right forefinger. Then lift the left end . The ribbon cassette will comeoffeasily . Caution- Neverliftleftendfirst. This may damage ribbon and printer head . 3 . Take a new ribbon . Hold the cassette as in step 2 . Put the left end on the axle ofthe gear on the left end of the printer head .
If it is difficult to push the left end down, raise it again . Hold the cassette with right hand . Press the gear on the cassette with left thumb . Then rotate slightly as indicated. See arrow on the cassette cover (Figure 2-6) . Figure 2 -6 Turn the gear as indicated by the arrow Secure the cassette on the printer head . The procedure may be repeated several times until it is easyto push the left end of the cassette onto the axle of the gear .
aometimes, tne cassette is put m correctly but part ot the ribbon rides up over the printer head as shown in Figure 2-8 . w . Put on tne removable Lover Plate . Place the Plate on the Guide Slot. Push into place gently as in Figure 2-9 . Figure 2-8 Part ofthe ribbon rides up over the printer head This may be caused by two reasons . 1 . The paper has been loaded before the ribbon . Remove paper and try again . 2 . The ribbon has been used for long time . Replace with new cassette. -8- Figure 2-9.
2.4 Loading Paper The paper roll may be placed inside the printer case When The paper roll is placed inside , the end should be underneath as Figure 2-11 caution Donl load as Figure 2-12 There are two ways to store the paper Roll : Place the Paper Roll inside of the printer case , as ex-factory , Load paper as fol lows : 1 . The removable Cover Plate must be taken off 2 . Cut the paper roll as shown in Figure 2-10 . \/ Figure 2-11 Correct paper roll loading - End is underneath Figure 2-10.

The paper entern the printer head and coroes out fiom the top of the printer head . To stop paper feeding release LF button . Pay attention to the polarity of the power supply . The central pin ofthe power jack on the printer is positive . The sptingplate in the side ofthe jack is negative .
Chapter 3. Operation Pin 3 .1 Parallel Interface Connection When a DPN-833/8233/8333 microprinter is linked with a PC, laptop,or other equipment with a standard parallel or serial interface, a standard cable can be used .
Signal level is TTL standard . The signal timing chart of parallel interface is shown in Figure 3-3 . BUSY 3 .2 Serial Interface Connection The cable mentioned in Section 3 .1 also can be used to link printer with computers or equipment with standard RS232C interface.

3 .3 Indicators and Switches Operation printer prints out Self-Test sample . There are two indicators and two button switches on the panel of the printer. The power indicator is labelled "P." . The other is the "SEL" indicator . A button switch is labelled "SEL" for selecting On/Off Line . Aother is labelled "LF" for paper Line Feeding. (See Figure 3-12 .) (2) With Power On and printer Off-Line, press and holdLFand thenpress SEL . Release both buttonstogether .
3 . Paper Feed Mode When print procedure is interrupted, SEL off, the printer enters Off-Line mode .If paper has tobe replaced press LF button Printer will feed paper without printing then release LF, printer will stop paper feed . Press SEL, printer re-enters On -Line mode . 3.4 Self-Test Self- Test cheeks condition of printer . lf the printer prints out the Self-Test sample correctly lt is working normally . Eventually faults are not caused by the printer but by the interface on host computer.
