Maximizing the operational life of your Braillo printer
Many 30-year-old Braillo printers are still in daily operation – a testament to their quality. To maxi-
mize the life of your Braillo printer, we strongly recommend using the correct tools, which come with
your printer; as well as following the correct procedures, which we prescribe in the manual and rein-
force in our training courses.
Additionally, just as the wrong wrench can ruin a nut, using poor quality Braille paper can ruin the
printer’s pins, print shoes and moveable parts by causing them to wear out prematurely. Failures due to
user negligence of this nature, just as repairs carried out by untrained personnel, may compromise your
warranty rights.
Braillo recommends using our specialized Braille paper and having your printer serviced by certied
technicians who have successfully completed our training course.
More information regarding our training courses can be found on our website:

2. INSTALLATION
Space:
The minimum space required for the Braillo 650 SW is approximately 4.7 m x 3.0 m (16 x 10 feet). It
is required at least 1.5 m free space behind the paper roll feeder (so that the paper roll can be replaced).
Environment:
Braillo Printers are made to operate continuously and to be reliable for many years. However, sensi-
tive electronic and mechanical parts require a suitable installation environment to ensure long and
trouble-free operation. Temperature should be between 15° - 30° C (60° - 86° F), and relative humidity
between 40 and 60%.
Maintain a clean environment because dust may clog the Printer - especially with high humidity. Too
low humidity should also be avoided to prevent electrostatic problems.
Some paper qualities may generate excessive paper dust. This should be removed with a vacuum
cleaner and a damp cloth. (About every 50,000 Sheets).
Electrical:
Single phase 230 volt (+/- 10%), 50/60 Hz, circuit breakers should be about 10 amperes.

2.1 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 2.2
“Removing the Printer cover”.
Any kind of lifting of the Printer must always be done from the baseboard at the bottom of the Printer,
or from the steel frame, and should be done with extreme care.
Make sure that your Braillo Printer has not been damaged in transport. Check if the outer 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.
Also check that the shipment contains the following items:
1 Printer
1 Ethernet cable 5 m (shielded)
1 USB cable 5 m
1 User’s guide B650 SW
1 Tool kit for service and maintenance
1 Test and packing list
1 Paper roll feeder
1 Friction bar / correction roll
1 Shaft, for the paper roll
1 Paper sample
1 Compressor (optional)

If any of these items are missing, please contact your distributor or Braillo Norway AS.
Important !
It is very important that the Printer’s specied voltage value (230 V, +/- 10%) corresponds with the
local mains power supply available.
If the plug on the mains power cable is to be replaced, note that the yellow/green wire is the grounding
(earthing) wire.
THE PRINTER MUST ALWAYS BE CONNECTED TO GROUND !
After the items are unpacked, make sure that the transport boxes is stored for eventual later use.

2.2 Removing the Printer cover
See gures below and on the next pages.
The cover is constructed of an aluminium frame which is fastened with four screws (G) under the
baseboard of the printer, there are one screw in each corner. Onto this frame the sides, front and back
panels are fastened. Some of these panels can be taken off for a better access e.g. for smaller repairs or
to connect to the electrical unit.
However, if the printer is going to be lifted or moved, and the printers own wheels cannot be used, the
cover must be taken off completely.
It can be done like this:
Disconnect the mains.
Open the panel (A) by turning the seven screws (B) 1/4 of a revolution - use a coin or a screwdriver.
Pull out the panel. Place it aside.

The paper sensor is a laser distance sensor, and is using a laser beam to check the distance to the paper.
If the distance is long (the paper is close to the oor) feeding speed is slow (or it will stop completely)
and if the distance is short, feeding speed is high. This will ensure that there is a constant slack of
paper between the Paper Roll Feeder and the Printer.
The paper is clamped between the feeder rolls with a compressed air cylinder. After a short period of
stand still, the pressure on the feeder rolls will be released. This is done to prevent deformation of the
paper.
Put the shaft in the center of the roll, and ensure that the shaft is approximately in the centre sideways.
Fasten the shaft. The roll must be placed so that the paper is rolled off at the top. (See gure).
Place the paper roll with the shaft already fastened just behind the Paper Roll Feeder. Lift off the cor-
rection roll with the friction bar and set aside. Use the crank to lower the roll lift until the lift is below
the shaft in the roll. Move the roll forward, make sure that the shaft is situated just above the notches,
while turning the crank to raise the roll lift. Turn the crank until the roll is lifted above the oor. Put the
correction roll with the friction bar on top of the paper roll like on the gure below.
Remove and throw away the rst rounds of paper on the paper roll (to get rid of e.g. sand, dust and dirt
after rolling the paper roll on the oor).
The paper line must go in between the friction bar and the correction roll. Ensure that the friction bar is
resting on top of the roll.
Now the paper must go through the feeder rolls. If turned on, the motor will feed some paper, and the
paper can be inserted into the Printer.

2.5 Compressed air
This equipment requires clean, compressed air, minimum 7.0 bar @ 100 l/min., and max. temperature
50° C to the regulator to function. To make this compressed air, you will need to use some sort of com-
pressor. No matter what kind of compressor is chosen, there are some important things to remember.
First, please read the enclosed instruction manual for the compressor!
There are many different compressor types on the market, and this chapter will not deal with a particu-
lar compressor, but will discuss the topic more in general. Please see the gure below for an example,
but refer to your compressor manual for the specic information.
Normally a compressor have two pressure gauges and a pressure regulator tted. The rst gauge is
measuring the tank pressure (before the regulator) and the second gauge is measuring the output pres-
sure (after the regulator). The pressure at the compressor outlet must be adjusted to approx. seven bar.
This can be controlled at the output pressure gauge.
To have long and trouble free operation, the air must be ltered and free from oil and water.
When air is compressed in a compressor, the air temperature is rising. So the air entering the tank will
be hot. When the air is cooling down, the humidity in the air will condensate inside the tank. So the
warmer and more humid the air entering the compressor is, the more water condensates inside the tank.
The compressor is lubricated with oil and small amounts of oil may also get into the tank.
This means that the tank must be drained for oil and water on a regular basis.
If the air is supplied from the smaller types of compressors delivered from Braillo Norway AS, it is
required to keep the compressor in a similar environment as described for the Printer itself. (Tempera-
ture 15 - 30°C (60 - 86°F) and rel. humidity 40 - 60%).

Output pressure gauge
(adjust to 7 bar)
If the compressor is placed in a more harsh
environment, it might be necessary to take
further precautions to remove oil and water
from the air.
Basic elements on a compressor:
Filtering and drainage
To stop oil and water from getting into the Printer, there are lters and drainage units in the line.
Some of this lters need to be drained, and some is automatically drained.
How often the manual draining has to be done depends on many things e.g. the temperature and
humidity in the environment around the compressor and the workload on the compressor. The more the
compressor runs, the hotter it will be and therefore it will produce more oil and water. So the best way
is to learn from experience in the different situations.
There is an additional lter/drainage/regulator inside the Printer. This one has automatic drainage, so it
will empty itself whenever it is something to drain.
When the compressor is starting, the tank pressure is zero (or very low). The pressure will then start to
raise slowly. Because of this slow increase, the drainage valve might leak out the pressure.
To solve this problem, a ball valve is fitted on the pipe nearby the compressor. This ball valve must be
closed until the compressor has filled it’s tank. Then open the ball valve and the drainage valve will be
closed.
When the compressor is empty:
1. Close the ball valve.
2. Turn on the compressor.
3. Wait for the pressure to reach about 6 bar.
4. Open the ball valve.
5. Ready.
