If your text-fi le is OK, the problem is caused by the printer. On earlier models of Braillo printers, this could be caused by either a electrical problem or a mechani- cal problem. But on this model of printer, there is integrated a self-diagnostic system that is checking the magnets continuously during printing, and this will trigger an alarm if it detects some electrical problems with the magnets.
Page 38
B 400 Series 3 BRAILLO NORWAY AS ● Possible reasons for errors: See fi gures on the next page. If a dot from a certain printing pin is missing regularly, the reason might be one of the following: Defective magnet (The self-diagnostic system will fi nd this one fi rst).

B 400 Series 3 BRAILLO NORWAY AS ● Magnet rack, disassembly, step by step. There are two main reasons for disassembling the magnet rack. It could be to replace some parts, i.e. a defect magnet, a worn pivot arm, or it could be for regular maintenance.
Page 42
B 400 Series 3 BRAILLO NORWAY AS ● Step 2. Remove the two nuts holding the supportlist, and then remove the supportlist. Supportlist Step 3. Remove the two bolts holding the pivotarm fastener, and then carefully remove the pivotarm fastener. The magnetrack is now disassembled.
B 400 Series 3 BRAILLO NORWAY AS ● Magnet, replacement Please observe that the numbering on the magnets in a magnet rack, always starts at “one” at the end where the connections are. (It does not refer to dot number, character number or column number!).
Page 44
B 400 Series 3 BRAILLO NORWAY AS ● Step 2. Pull out the defect magnet with, e.g. a narrow pair of “needle nose” pliers. Magnet Step 3. Check the magnets internal resistance if you have an ohm-meter available. The resist- ance should be from 185 ohm up to 240 ohm.
Page 45
B 400 Series 3 BRAILLO NORWAY AS ● Step 4. Replace the defective magnet with a new magnet in its place. Note: The spikes on one of the sides on the magnet. These spikes must be oriented the same direction as the rest of the magnet’s spikes in the magnet rack.
B 400 Series 3 BRAILLO NORWAY AS ● Magnet rack, cleaning Remove the magnet rack as described in chapter 4.3 “Magnet rack, removal”.

Now use a damp cloth moisted with cleaning alcohol to wipe off the surfaces as described in the fi...
B 400 Series 3 BRAILLO NORWAY AS ● Magnet Rack, adjustment Before replacing the magnet rack in the printer, two adjustments must be checked. The fi rst one is the distance between the support list and the pivot arms. This is the travelling distance for the pivotarm.
Page 48
B 400 Series 3 BRAILLO NORWAY AS ● The second adjusment is the pressure the spongelist exerts against the pivot arms. The spongelist works as a return spring for the pivot arms. The correct adjustment is when the spoungelist is slightly pressing against the pivot arms, but the pivot arms can still move freely.
B 400 Series 3 BRAILLO NORWAY AS ● Magnet rack, refi tting and adjusting Please see fi gure below: Before putting the magnet rack back on the printer, make sure that that the magnet rack itself is adjusted as described in the previous chapter.
Page 50
B 400 Series 3 BRAILLO NORWAY AS ● The magnet rack must be adjusted in two directions, horisontal and vertical. The horisontal adjustment is done fi rst. This adjustment positions the magnet rack correctly in relation to the short pivot arms. If the printer prints too many or too few dots, the horisontal adjustment could be the problem.
Page 51
B 400 Series 3 BRAILLO NORWAY AS ● When the arrows at the end of the shafts are pointing in the opposite direction of each other, the short pivot arms will be approx. positioned like in the fi gure below:...
Page 52
B 400 Series 3 BRAILLO NORWAY AS ● Next is vertical adjustment. Note! The printer must be in the “printing position” when checking this distance. Vertical adjustment approx. 1 mm (Will be affected by i. e. paper quality). The vertical adjustment of the magnet rack sets the pressure of the printing pins when making dots.
Page 53
B 400 Series 3 BRAILLO NORWAY AS ● Adjust upwards by loosening the upper nut and then tighten the lower. Loosen these screws Note! Adjust in small steps, only 1/4 of a revolution at a time. Then test the braille quality.
