1. INSTALLATION
1.1 Requirements of Installation Site
Table:
The Printer should be placed on a sturdy table. Note: this printer weighs 145 Kg.
Space:
The space requirement for the Braillo 200 is approximately 1.25m x 1.5m (4 x 5 feet).
Distance to the computer:
Serial communication: Up to 25 metres (cable distance) fromthe computer without special transmission
precautions.
Parallelcommunication: Up to 7metres (cable distance) fromthe computer without special transmission
precautions.
Environment:
Braillo Printers are made to operate continuously and to be reliable for many years. However, sensitive
electronic and mechanicalpartsrequireasuitable installationenvironment to ensurelong and trouble-free
operation.
Failure to meet the installation requirements may relieve the supplier of any warranty responsibilities.
ThePrinterrequiresnormalofficeenvironmentalconditions:Temperaturesbetween15-30°C(60-86°F),
and relative humidity between 40 and 60%.
Maintain aclean environment because dust mayclogthe Printer -especially with high humidity. Too low
humidity should also be avoided to prevent electrostatic problems.
Some paper qualities maygenerate excessive paper dust. This should be removed with avacuum cleaner
and a damp cloth. (About every 50,000 Sheets).
Be sure to consult your distributor/supplier for further details concerning the installation site.
1.2 Unpacking
Unpacking and installation can be done by the user.
After unpacking the Printer, the cover must be removed before lifting the Printer. See chapter 1.3
"Removal of Cover".
Anykind oflifting ofthe Printer must always be done fromthe baseboard at the bottomofthe printer, and
with extreme care.
Make sure that your Braillo 200 has not been damaged in transport. Check if the packing is damaged; If
so, it is possible that the Printer has also been damaged or scratched. If any damages are found, please
contact your distributor or Braillo Norway AS immediately.

Please read this manual carefully before starting the Printer!
Also check that the Printer is accompanied with the following items:
1Power cable for the Printer
2Data cables (serial and parallel)
1Serial adapter (9-25 pin)
1A small stack of paper
1Instruction manual
1Toolkit for service and maintenance
1Test and packing list
If any of these items are missing, please contact your distributor or Braillo Norway AS.
Important !
Itis veryimportant thatthe Printer'sspecifiedvoltageand frequencyvaluecorresponds withthe localmain
power supply available.
If the plug on the mains power cable is to be replaced, note that the yellow/green wire is the ground
(earth) wire.
1.3 Removal of Covers
See figures on the next page.
The side-panel (F) is removed by turning the two screws (V) 1/4 of a revolution - use a coin or a
screwdriver. Pull out the upper edge first, and then lift the side-panel up and out. Place it aside.
Disconnect the cables for the Operating Panel (G) and the Fan (H).
The cover can now be carefully removed by lifting the end with the fans slightly up and over on to the
baseboard. This small forward movement will free the side-panel end of the cover making it possible for
it to be tilted upwards.
The Printer can now be moved to the desired location. Afterwards, replace the cover (in reverse order of
above) and reconnect (G) and (H).
Plug the power cable in connection (L) and the data communication cable in the connection (R) or (S).
The side-panel (F) is mounted by placing the lower edge in first, and then pushing it against the cover.
Makesurethat the slot oneach screw's head is verticaland that the screws arealigned withthe holes, then
just push the screws in until a "click" is heard. Now the side-panel is secured.

Note! If text of less than two pages, or text with an odd number of pages, is received without being
followed by FF on the last page, the Printer will wait for more text or FF. This is due to the double-
sided operation of the printer. It waits for asignal that its buffer contains a full two page print job
before it begins printing.
1.4 Interfacing to Computer
Data can be transmitted fromthe computer to the Printer in two ways, either via the serial or the parallel
port. Serial transmission goes through an RS 232 Cinterface. Parallel transmission uses a Centronics
compatible interface.
Both connectors are of the 25 pin D-sub types, and are electrically isolated from the computer.
Serial communication:
Connect the enclosed cable, ensure that the computer and the Printer have exactly the same transmission
settings. If not, they can be changed either on the computer or the Printer. Braillo Norway recommends
a baud rate of 9600 Baud for quick and reliable communication.
Whenthe Printer is deliveredfromBraillo Norway, the serialport has the following transmissionsettings:
Baud rate: 9600
Parity: NO
Data bit: 8
Stop bit: 1
To change these settings on the Printer, see chapter 2.1 "Operating Panel". To make changes on your
computer, consult the user manual.
Ifchanges in the transmissionsettings are to be done onthe computer, we recommend that these changes
are added in the start-up file, AUTOEXEC.BAT, so that theyoccur automatically witheach startup. The
command for this might be: MODE COM1:96,N,8,1,P.
Parallel communication:
Connect the enclosed cable, ensure that the Printer is set for parallel communication, and start printing.
The Printer recognizes the following control codes:
CR: New line (fills the rest of the line with space).
LF: New line (fills the rest of the line with space).
Ifboth CR and LF, in any order, immediately follow each other, only one new line command is executed
by the Printer.
FF: New page (fills the rest of the page with space).
(After 2xFF the paper is fed one sheet forward, filling the rest ofthe page plus the next page with blank
space).
Ifthe lines are not terminated withCR orLF, the text which follows will be printed onthe same line, until
the line lengthset in the Printer is filled. Remaining characters will be wrapped to the next line. The same
situation will occur if FF is missing in the text, the text which follows will appear on the same page,
because there is no internal text formatting.
The Printer canalso be controlled by ESC-sequences to change itssettings and modes. Pleasesee chapter
2.7 "Escape-sequences".

Note!Whenusing more thanone FF command, make sure to have aspacebetweenthemtokeep them
separated. E.g. FF FF FF.
To have one sheet (two pages) printed, one of the following sequences must be executed:
Double-sided printing:
A) Two pages full of text.
B) More than one page of text and one FF.
C) Less than one page of text and two FF.
D) Two FF-commands.
E) Less than one/two pages and depress Dump Buffer.
Single-sided printing:
A) One page full of text.
B) Less than one page of text and one FF.
C) Less than one page of text and depress Dump Buffer.
Connecting the Printer to the Mains and Computer.
See the figure below.
Connect the enclosed mains power cable to the inlet (L). If the plug on the mains power cable is to be
replaced, observe that the yellow/green wire is the ground (earth) wire.
With parallel communication, use connector (R). With serial communication, use connector (S).
A: Fuse, magnet rack A
B: Fuse, magnet rack B
C: Fuse, magnet rack C
D: Fuse, magnet rack D
E: Main switch
H: Outlet, fan

2. OPERATING
2.1 Operating Panel
There is an audio alarm which sounds if a problem has occurred, and the display will show what has
happened.
There are three sheet counters. The one at the right-hand side of the display shows the total number of
printed sheets and cannot be reset.
The remaining two counters -Count1 and Count2, are displayed one-at-a-time on the left-hand side of
the display and can be reset.

Description of Functions of Operating Panel
COUNT1 / COUNT2
Selects between sheet counter (not pages!) 1and 2. When this button is in the outer (released) position,
counter 1is displayed on the left-hand side ofthe display, and when the buttonis in (depressed), counter
2 is displayed.
DUMP BUFFER
During normal double sided printing, a volume of text of less than two pages will not be printed. This is
because the Printer is waiting for afull two page print job. By pushing DUMP BUFFER, the text
remaining in the buffer will be printed. See chapter 1.4, "Interfacing to Computer".
PRINT VALUES
Prints the current values of the LAYOUT, I/O and ASCII-TABLES.
See chapter 2.3, "Print Values".
SCROLL
Scrolls through the menus activated by:
I/O, ASCII-TABLES, LAYOUT 1, LAYOUT 2, LAYOUT 3 or LAYOUT 4 buttons.
RESET COUNT
Resets the sheet counter selected by COUNT1/COUNT2.
TEST PRINT
This button has two functions: Test Print and Ready/Continue.
Test Print:
1st push down:
PrintsaX-patternonbothsides ofthe sheet whichshows each pin fromeach magnet rack printing
on a separate line. Useful when searching for missing dots.
2nd push down:
Prints full cells and emptylines, together with the ASCII-table on both sides of the sheet. Useful
for testing the printing pressure adjustments, and to see how the paper tolerates tightly grouped
dots.
3rd push down:
Printsfull cells and emptylines, together with the ASCII-table single-sided. Usefulfortesting the
printing pressure adjustments.
4th push down:
Prints atest pattern made of dot 1,3,5 and 2,4,6, single-sided. Useful when searching for extra
dots.
5th push down:
As 1st push down etc.
Ready/Continue:
Whenthe Printer runs out ofpaper, the message PAPEROUT is shownonthe display. Insert new
paper, and push TEST PRINT in and out, and the printer will continue printing the last print job.
Do not use RESET PRINTER as this will clear the print job from the Printer's memory!

Note! This button will not change between the 6 and 8 dot print mode, it just displays which ASCII-
tables that will be used in these modes.
Note! Scrolling trough the resident ASCII-tables will clear any user table that has been downloaded
from the computer. If this table is to be activated again, it must be reloaded from the computer.
I/O - Input/Output
Selects between serial and parallel port, and sets the data transmission values for the serial port.
1st push down: Displays which port is active.
To select serial or parallel port, the button must be depressed and then released. Now, while the display
still shows the active port, press SCROLL to select the other port.
If the serial port is active, a2nd push down will make it possible to use SCROLL to adjust the settings
for the serial port.
ASCII-TABLES
This button has two functions:
It selectswhich 6and 8dot ASCII-table to be active for braille conversion and it displays the 6and 8dot
ASCII-tables currently active.
1st push down:
Displays the active ASCII-table, number and country for the 6 dot mode.
2nd push down:
Displays the active ASCII-table, number and country for the 8 dot mode.
To select from the 8 resident ASCII-tables in the Printer, the following procedure should be used:
Push the ASCII-tables button, release it, then push it once again and hold. Now it is possible to change
the active ASCII-tables with the SCROLL button. ASCII-table pair number one will be displayed first.
(If there has been apair of ASCII-tables loaded from the computer, these will be displayed first). If
SCROLL is released, and pressed again, ASCII-table pair no. two will be displayed. This continues until
pair no. eight is reached, whereafter it will start at pair number one again.
LAYOUT 1
Selects sheet length, line length or Single/Double -sided printing.
Use SCROLL to choose each setting.
LAYOUT 2
SelectsnormalorZ-fold printing, if page 1is to be upordown, and to choose between 6and 8dot braille.
Use SCROLL to choose new settings.
LAYOUT 3
Selects the line spacing.
The line spacing is adjustable in steps from 0 to 16. In millimetres this will be from 0to 5.08 mm. (One
step equals 0.3175 mm). The setting 16 is the standard line spacing, 5.08 mm (0.2"). 8is the setting for
graphic, 2.54 mm (0.1"), and so on.
The function “Single or Double line spacing” will double the given line spacing. If, e.g. the current line
spacing is 13 steps (4.1275 mm), selecting Double line spacing will increase it to 26 steps (8.255 mm).
Use SCROLL to choose new settings.

Note! Please keep in mind that there is adifference in the terms “page length” and “sheet length”. By
page lengthwe meanthe number oflines oftext to be printed on apage, and by sheet lengthwe mean
the physical size of a sheet of paper in inches.
The number oflines which canbe printed onapage, is dependent onwhether 6or 8dot braille is used,
the selected line spacing, and the page length settings.
LAYOUT 4
Selects Page Adjust and Page Margin.
The “Page Adjust” can have one of the following values:
NoFFed: No form feed. This setting will cause the printer to print continuously. There are no
pagebreaks, and it is possible to print an “infinity long sheet”.
Max: Maximum. This is the standardsetting, and will give amaximumnumber oflines per page.
How many lines that will fit on a page will depend on, e.g. the sheet length, if it’s 6 or 8
dot braille, the line spacing, and margins.
Max-1 to -9: Maximum, -1 to -9. This setting will decrease the number oflines on each page with 1 to
9, (depending onthe selected number). If, e.g. the maximumnumber oflines would be 29,
and the setting “Max-4" is selected, the resulting number of lines will be 25.
This functionwill centrethe text vertically onthe page, to keepthe topand bottommargin
approx. equal.
The “Page Margin” function will adjust the page margin in steps from0to 20. The standard setting is 8,
(8=normal).The pagemarginwillgive different effect whenusedonsingle-sided,compared withdouble-
sided. Ondouble-sided printing, one step is equal to 0.6350 mm, and the text will be centred vertically on
the page. If, e.g.apage margin on6steps is selected, the printer will print closer to the edges ofthe paper,
and if apage margin on20 steps is selected, it will give alarger page margin. This will affect bothtop and
bottom margins, i.e. page margin.
On single-sided printing, however, the page margin will actually work as atop margin. (Note! The page
lay out must be set to normal to be able to do the following). One step is equal to 0.6350 mm. It will
“push” the text downwards the sheet. When the text reaches the bottom, (meaning that there will not be
enough space on this page for the last line), this line will wrap over to the next page.
Use SCROLL to choose new settings.
FINE ADJUST
Positions the paper.
Each push down moves the paper a distance equal to 0.5".
FORM FEED
Advances the paper to the next sheet.

BRAILLO MNORWAY AS B 200

Note! The Current Values are saved in the battery-backup memory, and they will remain even if the
power is turned off.
RESET PRINTER
Resets the CPU unit and clears the buffer.
Must always be used if an error occurs (Printer Error in the display).
RESET ALARM
For alarms, the audio alarm can be reset (e.g. Printer Alarm, Out of Paper).
For errors (Printer Error in the display), however, the RESET PRINTER must be used.
Using the Menu Buttons
With help of the menu buttons (LAYOUT 1, LAYOUT 2, LAYOUT 3and LAYOUT 4) the current
values can be changed.
The first push of a menu button shows which setting is currently active - its current value.
Ifthese settings are correct, wait afew seconds for the timeout to expire, or press the RESET PRINTER
button and the setting will remain.
If you would like to change one of the settings, push the button several times, until the desired function
is shown on the display, then hold it down. By using SCROLL, the complete menu for the function can
be reviewed in the display. When the correct value is shown, release the button and either wait for the
timeout, or use RESET PRINTER.
The I/O and ASCII-table buttons differ slightly from this routine. Please see their button descriptions
previously in this chapter.

2.4 Messages/Error Messages
The text in the display can be divided into three groups; Messages, Alarms and Error Messages. With
Messages, the Printer operates normally. With some Alarms, the Printer can be operated to a certain
degree, while other Alarms are like Error Messages, in that the Printer cannot be operated, and RESET
PRINTER must be used.
The audio alarm (BEEP) is sounded for both alarms and error messages.
Messages:
1When DUMP BUFFER is used, and the input buffer is
empty, the message "BUFFER empty" is shown on the
display. The Printer is then ready to begin a new print
job. Note: If there is text remaining in the buffer and
"Dump Buffer" is not used, the text will appear at the
beginning of the next print job.
2When PRINT VALUES is used, and the line length is set
to less than 36 characters, this message will appear on
the display. To print the current values, first set the line
length to 36 characters or more.
Alarms
1When the Printer runs out of paper, the audio alarm is
sounded, and the Printer stops at the end of the next
page.To continue printing, press RESET ALARM and
then TEST PRINT after the paper has been replaced. For
information, see TEST PRINT - Ready/Continue, in
chapter 2.1 "Operating Panel".
If the alarm is sounded when there still is paper in the machine, this may have been caused by
one of the following:
A. Paper dust in the paper out sensor.
B. The paper guide which the paper out sensor is attached to might be bent or damaged,
so the distance from the sensor to the paper is too big to detect the paper.
C. The sensor is not connected.
If one of these problems occurs, clean the sensor, make sure that it’s connected to the
motherboard, and check that the sensor is not more that 2 mm from the paper surface.

Printer
Buffer Overflow
Printer Alarm
Overrun/Framing
Printer Alarm
Parity
Printer Alarm
ESC-Sequences
The following alarms are usually caused by a problem with the handshake in the data communication
between the computer and the Printer, and it will be necessary to press RESET printer.
The text which remains in the buffer during these alarms can be printed by using DUMP BUFFER.
However, during these alarms one must check the transmission parameters for both the Printer and the
computer, and also possibly the software in use. If any changes are made on the Printer, one will have
to RESET PRINTER to register these changes.
4This alarm indicates that the computer has not registered
that the input buffer in the Printer is full, and continues to
send data which causes the buffer to overflow.
The text which remains in the buffer can be printed by
using DUMP BUFFER.
If this alarm occurs, check the transmission parameters
for both the Printer and the computer, and also possibly
the software in use.
5Error in at least one of the following transmission
parameters: Baud rate, no. of data bits and / or no. of
stop bits. If this alarm occurs, check the transmission
parameters for both the Printer and the computer, and
also possibly the software in use.
6Error in the parity check in serial communication. If this
alarm occurs, check the transmission parameters for both
the Printer and the computer, and also possibly the
software in use.
7Some irregularities have been detected when receiving
escape-sequences. If this alarm occurs, check the
transmission parameters for both the Printer and the
computer, and also possibly the software in use. If the
escape-sequences are sent by a batch-file or are
integrated in the text-file, be sure that the correct ASCII-
value combinations are used.
