2. INSTALLATION
Space:
The minimum space required for the Braillo 400 S is approximately 1.25m x 1.5m (4 x 5 feet). It can be
useful to have more space behind the printer so that one can replace the boxes of paper.
Distance to the computer:
Serial communication: Up to 25 metres (cable distance) from the computer without special transmis-
sion precautions.
Parallel communication: Up to 7 metres (cable distance) from the computer without special transmis-
sion precautions.
Environment:
Braillo printers are made to operate continuously and to be reliable for many years. However, sensitive
electronic and mechanical parts require a suitable installation environment to ensure long and trouble-
free operation.
Failure to meet the installation requirements may relieve the supplier of any warranty responsibilities.
Temperatures 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).
Be sure to consult your distributor/supplier for further details concerning the installation site.

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
“Removal of 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 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 printer is accompanied with the following items:
1 Power cable for the printer
2 Data cables (serial and parallel)
1 Serial adapter (9-25 pin)
1 A small stack of paper
1 User’s guide
1 Toolkit for service and maintenance
2 Paper shelfs with screws
1 Test and packing list
If any of these items are missing, please contact your distributor or Braillo Norway AS.
Important !
It is very important that the printer’s specifi ed voltage value (220V, +/- 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.
After the printer is unpacked, make sure that the transport box is kept for eventually later use.

2.2 Removal of cover
See fi gures below and on the next pages.
The cover is constructed of a 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
t 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.
