    BRAILLO B 300 S2.1 4.11 Unrecoverable errors: When there is an unrecoverable error, the display will show what has happened e. g. “General failure, Beam wheel failure”. When this kind of errors occurs, the printer must be reset or switched off and then switched back on again. The job currently being printed has to be sent once more from the computer. The different unrecoverable errors are: - Magnet failure A defect magnet has been detected during printing. The display will say “General failure, Magnet rack failure” and the magnet symbol will appear in the upper right hand corner of the display. The printer will stop.
  • Page 47 BRAILLO B 300 S2.1 - Beam wheel failure This means that the pulses from the Beam wheel sensor is not reg- istered in the electronics. This can be caused by e.g. defect sensor, disconnected sensor, broken main belt, or defect main motor. If you can hear the main motor start, it is probably something wrong with the sensor. But if you cannot hear the motor start, it is probably some- thing wrong with the main motor. Press Reset to continue.

  • Page 49: Test Print

    BRAILLO B 300 S2.1 4.13 Test Print The test print program is designed to ensure that the 168 printing mechanisms functions properly. This printer will do an electronic test on all of it’s printing mechanisms continuously during printing. However, this electrical test will not tell if something is wrong mechanically, and therefore it is recom- mended to print a few pages of test print before beginning the day’s production. By doing so, it’s quite easy to see if all printing mechanisms are functioning mechanically. This printer has both single-sided and double-sided (interpoint) test print patterns. The test print consists of four different patterns. See the description below: How to use the test print: Print Test Pattern: Main Menu - Warning - Service/Diagnostic - Warning - Print Test Pattern When entering this menu choice, a warning window will appear. This is to make the user aware that print jobs from the computer will not be printed as long as you are in this sub-menu.

  • Page 52 BRAILLO B 300 S2.1 Please see the figure on the previous page. The two shafts, one at the top and one at the bottom, are rotating synchronized. On each shaft there are eccentrics that are moving the beams and paper shoes up and down. This movement is used both to hold the paper and to make the dots. A row of dots is printed for each revolution of the shafts. The shafts must rotate three times to form a complete row of characters. Please see figure below: First revolution Second revolution Third revolution To be able to print interpoint (where both sides of paper are printed simultaneously), the back page is offset a little to the right and a little down to fit in between the dots on the front page. Please see figure below: Front page Back page (dashed lines) Dimensions on the 6 and 8 dot Braille cell, measured in mm.

The parts in the upper left of this drawing is one of the magnet racks. The parts in the lower right, are the beam and paper shoes. The magnet racks itself do not move, but the beams and the paper shoes are moving up and down for every revolution of the eccentric shafts. Inside each magnet rack there are 42 electrical magnets. The magnets are controlling the long pivot arms.

  • Page 56: Troubleshooting, Incorrect Braille

    BRAILLO B 300 S2.1 Troubleshooting, incorrect Braille If any errors have been found in some of the characters in the printed text during proofreading, the first thing to do is: Check the characters in the text-file in the computer to find out if the error could come from the text- file and not from the printer. If your text-file is OK, the problem is caused by the printer. The errors could be caused by either an electrical or a mechanical problem. On the electrical side, there is integrated a self-diagnostic system that is continuously checking the magnets during printing, and will trig an alarm if it detects some electrical problems with the magnets. So, if no alarm is trigged, the errors found are most likely caused by some faulty mechanical parts or maybe dirt clogging the moving mechanisms. Inside the printer there are four identical magnet racks, named from A to D. Each magnet rack con- tains 42 printing mechanisms. There are totally 168 printing mechanisms to choose from when the error search begins. See section 5.1 ‘Printing principle’ on page 50 for more information. If the printer has been printing a lot (a lot could be after a year, or after 1000 printing hours, depend- ing on what comes first) errors in the characters could occur. If this happens, it could just be that the printer needs regular maintenance. See section 5.6 ‘Magnet rack - cleaning’...
  • Page 57 BRAILLO B 300 S2.1 Possible reasons for errors: See figures on the next page. If a dot from a certain printing pin is missing regularly, the reason might be one of the following: Defect magnet (The self-diagnostic system should find this one first). Broken short pivot arm. The long pivot arm cannot move because of dirt. The printing pin is stuck because of dirt, causing the short pivot arm to miss the long pivot arm. Errors in the magnet rack board. If dots from several printing pins are missing now and then, the reason might be one of the following: The sponge list is pushing too hard on the long pivot arm.

  • Page 60: Magnet Rack - Disassembly, Step By Step

    BRAILLO B 300 S2.1 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. defect magnet or worn pivot arm, or it could be for regular maintenance. The magnet racks can be considered as the part of the printer that will have the greatest influence on the dot quality, so it is very important to know how to deal with them.

  • Page 66: Magnet Rack - Adjustment

    BRAILLO B 300 S2.1 Magnet Rack - adjustment Before placing the magnet rack in the printer, two adjustments must be checked. The first is the distance between the support list and the pivot arms. This is the travelling distance for the pivot arm. And it should be adjusted to about 0.8 mm using a feeler gauge. Adjust the nuts on both ends of the magnet rack. If the 0.8 mm feeler gauge goes half way in, and the 0.9 mm feeler gauge does not go in at all, consid- er the adjustment OK.

    BRAILLO B 300 S2.1 Magnet rack - refitting and adjusting Before putting the magnet rack back on the printer, make sure that the magnet rack itself is adjusted as described in the previous section. When placing the magnet rack in the printer: Put in the four fastening screws, but do not tighten them. Slide the magnet rack horizontally away from the printer, so that the magnet rack is touching the horizontal adjustment screws. This will en- sure that the magnet rack is in the exact same position as before it was taken off the printer. See next section regarding correct adjustment of the magnet racks. Note! All explanations refer to one magnet rack, but these adjustments must be done on all four magnet racks. Pull back against these positioning screws on both ends...
  • Page 68 BRAILLO B 300 S2.1 The magnet rack must be adjusted in two directions, horizontal and vertical. The horizontal adjustment is done first. This adjustment positions the magnet rack correctly in rela- tion to the short pivot arms. If the printer prints too many or too few dots, the horizontal adjustment could be the problem. Then the vertical adjustment is done. This adjustment will affect the pressure the pivot arms put on the printing pins. This directly affects the shape of the printed dots. Vertical Horizontal adjustment adjustment To be able to adjust the magnet rack correctly, it is necessary to put the printer in “printing position”. This is done by rotating the main belt by hand until the arrows at the ends of the shaft are pointing exactly 180 degrees away from each other. It is possible to get the mechanism to balance in this position, but you can also lock the shafts with e.g. a self locking wrench (vice-grip pliers).
  • Page 69 BRAILLO B 300 S2.1 When the arrows at the end of the shafts are pointing in the opposite direction of each other, the short pivot arms will be approximately positioned like in the figure below: Approx. 0.2 mm (As close as possible without touching when the short pivot arm is moving up and down). The gap between the long and the short pivot arm should be approximately 0.2 mm.
  • Page 70 BRAILLO B 300 S2.1 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. The amount of pressure needed depend on several things. The first (and most important) is the paper quality. The second, is the personal preference the of dot quality. So the best way to find the correct level of vertical adjustment, is to first decrease the pressure so the dots will be very faded and weak. Then readjust the pressure up in small steps until the dot quality is satisfactory. By doing this you can make sure that you are running the printer with just enough pressure to make good dots, but not so much pressure that the printer will be worn/damaged. From our experience we have found that the vertical adjustment should be approximately 1 mm, but if the Braille dots are too weak, you may adjust the magnet rack tighter in small steps (increase the 1 mm distance). Please see figure on next page:...
  • Page 71 BRAILLO B 300 S2.1 Adjust upwards by loosening the upper nut and then tighten the lower. Do this on both ends, so the magnet rack stays levelled. Note! Adjust in small steps, only 1/4 of a revolution at a time. Then test the Braille quality.
  • Page 72 BRAILLO B 300 S2.1 Note! When adjusting the magnet racks vertically, observe that magnet rack A and B must be moved upwards to increase the pressure, and magnet rack C and D must be moved down- wards to increase the pressure. (Moving away from the paper increases pressure). PAPER...

  • Page 83: Inductive Sensors - Adjustment

    BRAILLO B 300 S2.1 5.18 Inductive sensors - adjustment This printer uses inductive sensors in three places. One for the main timing wheel on the lower shaft, and two are controlling the movement on the paper feed mechanism. It is possible to check if the inductive sensors are functioning by looking at the rear end where the cable enters the sensor. Inside the sensor is a little LED lamp that will be lit if a magnetic object is in front of the sensor. So by having the power turned on, and at the same time turning the shafts, the light should go on and off. When replacing/adjusting the sensors, the gap between the timing wheel and the sensors can be maximum 0.6 mm. Check this for the whole revolution of the timing See figure below.

    BRAILLO B 300 S2.1 Escape-sequences What is an escape-sequence? An escape-sequence is the name for a code which is sent to the printer from the computer to change the parameters which control the way the printer works. All parameters that can be set via the opera- tor panel, can also be changed with escape-sequences.
  • Page 102 BRAILLO B 300 S2.1 Note! The escape-sequences will be executed immediately if the printer is not running. How- ever, if the printer is running, the escape-sequences will keep their place in the document, and will be executed when this particular page is printed. Also keep in mind that any page format- ting command must be kept on the front page of a sheet. Then the command will affect both the front and back page, i.e. one sheet. If there are page formatting commands on the back page of a sheet, these commands will be skipped. Please see the following explanations on how to combine different values to get the different es- cape-sequences. Sheet length: Line length: ESC A nn - Sheet length. ESC B nn - Line length.
