PREFACE
TheEasyCoder71issimpletooperateandacosteffectivesolution
for your low volume label printing requirements.
The EasyCoder 71 uses direct thermal printing technology. The
labels are printed by moving thermal sensitive paper past a fixed
thermal printhead. The printhead heats small dot patterns (8 dots/
mm = 203 dots/inch) to form the desired labels.
TheEasyCoder71isdesignedto work withanycomputingdevice
capable of producing ASCII outputs. The connection is through
either the parallel Centronics port or the serial RS 232C port.
Connectioncableisnotincludedinthedelivery,unlessspecifically
ordered.
The EasyCoder 71 is delivered with a floppy disk containing a
driver program for Microsoft Windows. The driver makes it possi-
bletoproducebitmappedprintoutsfromalargenumberofstandard
programs run under MS Windows, e.g. MS Word, MS Excelor PC
Paintbrush.UBIhasdevelopedalabel-editingprogramcalledUBI
LabelShop,which runs under MSWindowsand iscompatiblewith
the full range of UBI EasyCoder printers.
The EasyCoder 71 can also be run by means of a special control
program described later in this manual. The program uses short
lines of ASCII characters to format the labels, enter text and bar
codes and control the printing. This makes it possible to use a
terminal, or a personal computer, that does not operate under MS
Windows.
The EasyCoder 71 can print labels or tags with a web width of up
to108mm (4.25")anda maximumprintwidth of 104mm(4.09").
A self-strip and label-taken sensor device is available as a factory-
installed option as well as a battery pack and an external display/
keyboard unit.

Note that no cable for printer-to-computer connection is in-
cluded, unless in case of EasyPak 71 or if ordered separately.
5. Check the separate transformer unit in regard to voltage rating
(120 VAC, 60 Hz or 220 VAC, 50 Hz).
6. Pull out the battery protection strip from the memory cartridge

before the battery pack must be recharged for approximately 13
hours.
To install a battery pack, proceed as follows:
1. Check that the mounting kit contains the following items:
(1) ea. Mounting Plate
(4) ea. M3x45 Mounting Screws
2. Disconnect the printer from any power source and from the
computer.
3. Remove the four (4) rubber feet from the bottom of the base of
the printer. (These feet can be pulled out by hand.
4. Using a Phillips screwdriver, remove the four (4) screws from
the base of the printer.
5. The printer cover will be loose at this point and the removable

loading self-adhesive labels. If labels are not flat on the backing
paper, the exposed edges can stick to your printer and cause
problems.
Note the difference between how labels and tags should
be wound on the label roll:
❑Labels should be wound with the labels facing
outwards and unroll from the top of the roll.
❑Tags should be wound with the thermal layer facing
inwards and unroll from the bottom of the roll.

UBI EasyCoder 71 – Installation Instructions
Printing Test Labels The Test Mode automatically adjusts the paper feed according to
thelengthofthelabelsortagsofthepresentpapersupply1.Oncethe
paper feed has been adjusted, it needs no readjustment until labels
or tags of a different length are loaded, or you change the memory
cartridge. Power off does not affect the paper feed length.
TheTestMode alsoallowsyouto checktheprintout quality andto
get information on the memory setup and the real-time clock. You
can enter the Test Mode without having connected the printer to a
computer.
To enter the Test Mode, proceed as follows:
1. Press down the Feed button and keep it that way until further
notice.
2. Turn on the power.
3. The first Test Label will be printed. It contains the following
information:
• Software version.
• Current serial communication setup.
• Test pattern for checking the printhead dots.
• Informationonthe sizeofvarious partsofthe RAM memory.
• Information on number of character bits, code page and
country code for the selected character set.
• Date and time according to the printer's optional real-time
clock (if installed, else 00:00:00).
4. If you continue to hold down the Feed button, a second Test
Label will repeatedly be printed with samples of the different
fonts and a bar code sample.
5. Release the Feed button.
6. Return to normal operation by turning off and on the power.

The selection of label size is not critical for the printer as the
printer stops after a gap anyway. However, your application is
using this value to set the paper size. There are a number
predefined sizes, all with a width of 100 mm (3.94") and with
different lengths between 14 and 150 mm (.55 –5.9"). You may
alsouse“UserDefinedSize”tosetanynotpredefinedheight,but

UBI EasyCoder 71 – Installation Instructions
With a few exceptions due to the limited physical size of the label
ortag,yourEasyCoder71willworklikeanymatrixorlaserprinter
operatingunderMSWindows3.1.However,beforestarting,please
read the following information.
Margins (left, right, top, and bottom)
It is important to set the margins in your application. These should
normallybesettozerotoallowforprintingontheentirefull-width
label.
Narrow labels and left margin
The printer will start printing at the extreme left edge of the label
path (compare matrix or laser printers). However, labels in
EasyCoder71arecentredto themiddle.Thus,to printonanarrow
label it will be necessary to set the left margin, i.e., move the print
to the right.
Label length autoadjust
The EasyCoder 71 is automatically measuring the label length by
feeding two blank labels the first time a form is sent to the printer
froma Windows applicationafter apower-up. This value is stored
in the printer as long as the power is on.
Memory restrictions
If the print image is too large to fit in the printer's memory, the
“Power” control lamp on the printer will turn orange and an error
messagewillappearonthescreen.Ifthishappens,turnprinterback
“on-line” by pressing the Feed key on the printer. When the
“Power” lamp turns green, the printer is ready.
To avoid memory overflow, reduce the amount of data sent to the
printer by limiting the label size. Do not design your label with a
frame that prints along the edges of the label, or too far to the right
side of the label.
Code 39 Bar Code Fonts
TheUBI EasyCoder 71 Windows Driver floppy disk contains two
Code39barcodefontswithdifferentresulotioninTrueTypeformat

MEMORY CARTRIDGE
The EasyCoder 71 is fitted with an easily exchangeable memory
cartridgethatcontainstheprinter'sentirePROMandRAMmemory
and the optional real-time clock circuit (RTC). As standard, the
memory cartridge contains 1 ×128 kbyte PROM and 256 kbyte
RAM (2 ×128 kbyte). The RAM memory can optionally be
expanded up to 512 kbyte (4 ×128 kbyte).
The RAM memory and the RTC are battery backed-up by means
ofacoin-typelithiumbattery(PanasonicCR20323V)fittedinside
the cartridge. The battery should be replaced at least once a year.
Proceed as follows:
1. Turn off the printer.
2. Pull the cartridge straight up.
3. Remove the Phillips screw on the side of the cartridge.
4. Separate the two sides of the cartridge by sliding one of them
slightly sideways and then pulling them apart.
5. Quicklyreplacethe battery. TheRAMpackageswill keeptheir
content for 5 minutes without any current from the battery.
6. Reassemble in reverse order and turn on the printer.
