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
. ltwill 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
. At this
point the receiving buffer of the printer will be cleared and all the
command parameters will be set to the default values
. The printer
entries normal operating mode

Introduction
DPN-833/8233/8333 is a new series of fast speed, general
purpose Impact dot matrix microprinter
. All members of this
series are small in size
,
light in weight
,
attractive in appearance
and easy in operation
.
The special features ofthis series are fast Speed and high
reliability
. This is the advantages of new hardware and
software design
. An 8-pin shuttle impact print head is adopted
.
Also Fast Paper Feed Function
-
twice the speed of printirg
-
is added
.
A font of 448 characters in the intenial ROM includes IBM* Character Set # 2, also Greek, German, French, Russian, Japanese and Chinese characters, math symbols,
specific meaning symbols and tabulation symbols
. Forty

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)
.

.3 Install
Ribhon Cassette
Ribbon cassette has been put inside the printer before packeng
When the printing becomes faint after long use , put in a new
ribbon cassette
. The removable cover plate must be removed
while inserting a new ribbon cassette
. Following pictures show
how to remove it
Figure 2-2
. Correct action
.
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
.

. 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
.

. 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
. Keep the right end ofthe cassette up as shown in Figure
2-5
.
Figure 2-5 Keep right end of cassette up
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)
.
Figure2-6 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
. Then press down the
right end of the cassette with the right thumb as shown in Figure 2-7
.

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
.

.5 Power Supply
The DPN-833/8233/8333 series printer uses a 5V DC power
supply.A power supply is specially made for this series and
is
recotntnended in Appendix F
. Insert the output plug of the power
.supply into the jack on the back of the printer
.
When using other
models of power supply, please pay attention to the voltage and current limits
.If the voltage is higher than
DC5.SVor lower than DC 4 5V, or the maximumm cunent is less than SA,the printer will not work normally and the printer head may be damaged
.
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
.
See Figure 2-14

.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
. This cable is with two standard 25 pin D type connectors, a male and a female, on two ends of this cable, and with 25 wire connectoon Other computers and equipment could also be connected by making a special cable The 25pin connector of parallel Interface on the back of the DPN-833/8233/8333 series printer is shown in Figure 3-1
