PRINTER BASIC Thank you for your purchase of the Braillo 650 SW2.1. Please read this manual carefully before install- ing and operating this printer. Key features • Prints interpoint, both sides of the sheet are printed simultaneously • Specially designed to print 4 pages/sheet (like e.g. newspapers, magazines) • Prints 650 characters per second • Self-test system that checks the magnets continuously during printing • Reliable, sturdy construction • Safety switches will turn the printer off if someone accidentally opens the cover while printing 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 certified technicians who have successfully completed our training course.

Page 9: Installation
BRAILLO B 650 SW2.1 INSTALLATION Space: The minimum space required for the Braillo 650 SW2.1 is approximately 4.8 m x 3.0 m (16 x 10 feet). It is required at least 1.5 m free space behind the Roll unwinder 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 when combined 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 min. 6 amps. Be sure to consult your distributor/supplier for further details concerning the installation site. Failure to meet the installation requirements may relieve the supplier of any warranty responsibilities. Viewed from above...

Page 21: Connect The Printer To The Mains And Computer
BRAILLO B 650 SW2.1 Connect the printer to the mains and computer Plug the mains cable into the inlet as shown in the figure below. Note! If the plug on the mains power cable is to be replaced with one that is compatible with the local electric contact points, observe that the yellow/green wire is the grounding (earthing) wire. Also make sure that you are connecting to 230 volts! THE PRINTER’S MAINS CABLE MUST ALWAYS BE CONNECTED TO GROUND! The connection to the computer can be done in three ways, either by Ethernet, USB, or WLAN. For USB and Ethernet, the connections are placed on the side of the printer together with the power inlet. The ethernet input is a regular RJ45 connector, and the USB input is a regular USB type B connector. The WLAN is transmitting/receiving via a small antenna placed close to the operator panel. If you connect to the computer with cable, there is no need to select between USB or Ethernet. The printer will connect to the input who receives data first. Meaning, if data comes on the ethernet, the USB will not be operative before the ethernet have finished the transmission. For instruction on how to install the printer on your computer, see chapter 3 ‘SETTING UP THE COM- PUTER’ on page...
Page 22: Compressed Air
BRAILLO B 650 SW2.1 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 compressor. No matter what kind of compressor is chosen, there are some important things to re- member. 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 particular compressor, but will discuss the topic more in general. Please see the figure below for an example, but refer to your compressor manual for the specific information. Normally a compressor have two pressure gauges and a pressure regulator fitted. The first gauge is measuring the tank pressure (before the regulator) and the second gauge is measuring the output pressure (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 filtered 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.
Page 23 BRAILLO B 650 SW2.1 Filtering and drainage To stop oil and water from getting into the Printer, there are filters and drainage units in the line. Some of this filters 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 filter/drainage/regulator on the Roll Unwinder. This one has automatic drain- age, 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.
Page 24: Place The Paper Roll
BRAILLO B 650 SW2.1 Place the paper roll Put the shaft in the center of the roll, and ensure that the shaft is approximately in the centre side- ways. Fasten the shaft. The roll must be placed so the paper end is pointing away from the printer at the top of the roll. (See figure). Paper direction Shaft Use the crank to lower the two arms so it is lower than the shaft in the paper roll. Then roll the paper roll carefully in between the two arms. When the shaft ends are correctly aligned above the notches, use the crank to raise the arms and lift the paper roll off the floor. Crank Notch for shaft...

Page 26: Power On
BRAILLO B 650 SW2.1 2.10 Power on The On/Off switch is placed on the printer, behind the back panel and can be reached through an opening in the panel. When the mains cable has been connected, and the power has been switched on, the printer will do it’s start up sequence. The display will stay black for a moment, then it will show a progress bar for the start up sequence. When it’s done, the display will show “Welcome, press the accept button to continue”. Press the button and the display will change to “Ready to emboss”. For safety reasons, there are mechanical switches on the printer cover. These switches will disable the possibility to run the printer if the side plates are removed. The paper feed unit will move a little back and forth to find the home position. If there is no paper inserted, the printer will start an alarm, and the display reads “Printer halted - Out of paper”. This is normal, and the sound can be silenced by pressing the mute button. Note that the printer will go into sleep mode when it has been inactive for 15 minutes. If that hap- pens, the printer will wake up if you touch the operating panel or send a file from the computer. It is also possible to manually put it in sleep mode by entering the main menu, and select the “Enter sleep mode” choice. The printer is now ready. Before continuing, please read chapter 4 ‘OPERATING THE PRINTER’ on page 38 carefully. On/Off switch...

Give the printer a identifiable Name and Location, for example ‘Braillo_<model number>’ 6. Your new printer is now configured and ready to use Note! If you use the default ‘Generic Text-only printer’ driver for USB printing on Linux you might run into is- sues where the driver will strip certain control characters and just print the text. It could also refuse to print certain documents which contain more than just printable text characters. Also make note that this driver will add margins around the text by default, which might interfere with the document formatting. The recommended driver on Linux is ‘Generic Raw Queue’ or similar raw forwarding driver. Ethernet on Windows Before starting, make sure the printer is powered on and connected to the network. You will need the printer’s IP address which can be found in menu Main Menu - Warning - Service/ diagnostic - Status / Software upgrade.

See ‘Status / Software upgrade:’ on page 55 for more information. The printer broadcasts itself using dnssd/bonjour. If you only have one Braillo printer on your network you can use this if your computer detects it. If you have multiple Braillo printers it is better to add them by their IP address to be sure you are configuring the correct one. 1. Find your distro’s Control Panel and find the dialogue to add a printer 2. Select ‘Internet Printing Protocol (ipp)’ 3. Use the network URI: ‘ipp://<IP-address>:631/printers/Braillo’ 4. Give the printer a identifiable Name and Location, for example ‘Braillo_<model number>’ 5. Your printer is now configured and ready to use Test the communication: To test if the Linux computer is successfully communicating with the Braillo Printer, the ‘lpr’ command can be used. Create or select a file that can be used for printing and enter the following command in a terminal: lpr -P <Braillo_Name> <file_to_print> Where -P means destination, <Braillo_Name> being that destination name, and <file_to_print> being a text file or file that is compatible with the Braillo Printer. The exact device name of the Braillo printer can be found by using ‘lpstat -t’.
Page 35: Wireless Network (Wlan)
BRAILLO B 650 SW2.1 Wireless network (WLAN) The configuring of the wireless network connection is handled through a special configuration mode where the printer creates a temporary Access Point. When connected to this AP the rest of the config- uration is handled trough a standard web page. To enter the WLAN configuration mode, navigate to: Main Menu - Printer setup - Network configuration - Conf. WLAN. See section ‘- Wireless configuration’ on page 59 for more information. A screen now shows up with the credentials needed to log on to the temporary configuration access point. The network name (SSID) is unique for this printer, but the password is generated and will differ every time you start configuration mode. Leave the printer in this state while you continue the configuration. Using a laptop, tablet, smart phone or other Wireless enabled unit with a web browser: 1. Connect to the temporary Access Point using the credentials in the printer display 2.

Page 38: Operating The Printer
BRAILLO B 650 SW2.1 OPERATING THE PRINTER The figure below is a schematic drawing on how the paper travels through the machine. Cutting Printing Stacking Feeding Unwinding Adjust to paper width All these adjustments are dependent on the paper roll width, so it can be wise to use a paper sample to set the width. It is recommended to start with the paper feeder unit nearest to the main belt (the right-hand one when looking in the direction the paper travels), because this will also determine the top margin on the sheet. The adjustment should be done in this order: 1. Move the feeder unit nearest to the main belt to the desired position. (Note the top margin). 2. Adjust the other feeder unit so the distance between them is equal to the paper width. 3. Put the paper into the Printer, and align the guides on the input tray.
Page 39 BRAILLO B 650 SW2.1 The numbers are indicating in which order the adjustments should be done. (The printer cover and the protection covers are removed in the figure to get a better view, but this adjustments can be done with the covers on.) End stop Stacker Feeder Input guides Paper feeder, adjust width Loosen the knobs and the bolts (without taking the knobs or bolts out). The two feeder units can now be moved sideways. Note that the unit on the side nearest to the main belt will also determine the top margin. Use a paper sample to find the correct distance between the two units. The paper sample should fit exactly in between the two units. Fix the units by tightening the knobs and the bolts.
Page 40 BRAILLO B 650 SW2.1 Input guides, adjust width Before you adjust these two guides, take the paper from the Roll Unwinder and put the paper through the printer, and place it accurately into the already adjusted paper feeder. Make sure that the paper is aligned correctly and goes straight through the printer. Then adjust the guides against the edges on the paper, this will keep the paper correct positioned and aligned during printing. Adjust to sheet width...

Adjust to paper width + e.g. 2 mm 1. Loosen these four knobs...
Page 42: Printing With B650 Sw
BRAILLO B 650 SW2.1 Printing with B650 SW This Printer is printing interpoint. It also print the text sideways on the paper. This way of printing is creating some confusion regarding the different terms used to describe the sheet of paper. Please see the figures below for the terms Braillo are using. The Printer can print in two different modes. These modes are called “2-page” and “4-page”. The name “2-page” is telling us that the number of pages on each sheet of paper is two. (One page on each side of the paper). In “4-page” mode, the Printer will print four pages on each sheet of paper. (Two at each side of the paper). By doing this, it is possible to put the sheets in a stable and stitch and fold in the middle. This way of printing makes it easy to produce e.g. a newspaper or magazine in braille. 2-page mode: 4-page mode:...
Page 43 BRAILLO B 650 SW2.1 The sheet in 2-page mode: Please see the figure below. The “Sheet length” is not a length you can set directly, but it will be a result of the margins and line length settings. Sheet length = Margin 1 + Line length + Margin 2 Sheet height = Paper roll width...
Page 44 BRAILLO B 650 SW2.1 The sheet in 4-page mode: Please see the figure below. The “Sheet length” is not a length you can set directly, but it will be a result of the margins and line length settings. Sheet length = (Margin 1 + Line length + Margin 2) + (Margin 2 + Line length + Margin 1) Sheet height = Paper roll width...
Page 45 BRAILLO B 650 SW2.1 Printing in 4-page mode: The number of pages sent to the Printer in 4-page mode, has to be a number that is possible to divide by four. E.g. a document that contains 7 pages of text, must have one empty page added to get a total of eight pages. And those eight pages will fit on two sheets. (8 pages divided by 4 = 2 sheets). Next, the text has to be sent to the Printer in the following sequence: Page 1, 2, 7, 8, 3, 4, 5 and 6. This formatting is normally done with computer software. To be able to move the belt between each copy of a document, the Printer also needs a command that will tell how many sheets the document contains. This command is an escape-sequence that must be sent to the Printer in the beginning of the document. This is done by sending the ASCII value no 27, then the letter P, and then the number of sheets. E.g. in the example above, the command would look like this: escP02 (There are software on the market that will do this formatting automatic). Here are some physical measurements to consider when adjusting the different settings : Max paper height: 330 mm (13.0 inch) (This is the same as the width of the paper roll). Max paper length: 584 mm (23.0 inch) Max no. of characters per. line: 44 char.

Page 62: Unrecoverable Errors
BRAILLO B 650 SW2.1 4.12 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. Check the log for the details. (Main Menu - Warning - Service/diagnostic - Warning - View Log) When trying to print after a defect magnet is found and replaced, the display will still show the magnet symbol in the top right hand corner. This is because you have to reset the magnet failure. To reset the magnet failure, you have to select the menu choice Clear magnet failure. See ‘Clear magnet failure:’ on page 55 for more info.
Page 63 BRAILLO B 650 SW2.1 - 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. The sensor can be tested manually on Main Menu - Warning - Service/diagnostic - Test Sensors. - Page self adj. failure The printer has detected position problems with the paper feeding on e.g. power up or resetting. Could be caused by e.g. a defect/discon- nected sensor or stepping motor. The sensors can be tested manually on Main Menu - Warning - Service/diagnostic - Test Sensors.

Page 65: Test Print
BRAILLO B 650 SW2.1 4.14 Test Print The test print program is designed to ensure that the 180 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.

Page 72 BRAILLO B 650 SW2.1 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 two times to form a complete column of characters. Please see figure below: First revolution Second revolution Third revolution Fourth 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)
Page 73 BRAILLO B 650 SW2.1 The drawing on this page is meant to help to understand the basic principle of how the dots are print- ed. Please also see the drawings on the next page. 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 45 electrical magnets. The magnets are controlling the long pivot arms. When a dot is going to be printed, the magnet is engaged, and the long pivot arm will be drawn against the magnet poles.

Page 76: Troubleshooting, Incorrect Braille
BRAILLO B 650 SW2.1 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 45 printing mechanisms. There are totally 180 printing mechanisms to choose from when the er- ror search begins. See section ‘Which magnet makes what dot?’ on page 77 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 5.8 ‘Magnet rack - cleaning’ on page 87, and sec- tion 5.27 ‘Maintenance’...

Page 79 BRAILLO B 650 SW2.1 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 silicone string is pushing too hard on the long pivot arm. The gap between the two pivot arms is too large.

Page 89: Magnet Rack - Refitting And Adjusting
BRAILLO B 650 SW2.1 5.10 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 90 BRAILLO B 650 SW2.1 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 91 BRAILLO B 650 SW2.1 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 92 BRAILLO B 650 SW2.1 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 93 BRAILLO B 650 SW2.1 First, loosen these two screws Then 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 94 BRAILLO B 650 SW2.1 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 124: Sw2 Stacker
BRAILLO B 650 SW2.1 SW2 STACKER The SW2 Stacker will stack the printed sheets in piles, where one pile can be a complete book or mag- azine. The stacker is also controlling the compressed air that drives the paper cutter inside the printer cabinet. Description of function When the printer is printing a sheet, the sheet will be catched by the rollers on the eject motors. The eject motors, one on each side of the sheet, runs slowly with low torque as long as the printer is printing. When it’s time to cut the paper, the printer sends a signal to the SW2 stacker control unit. The paper holder on the cutter locks the paper and the cutter cuts the sheet. Immediately after the cutting, the eject motors will increase the speed and torque and push the sheet into the stacking unit. When the sheet is detected by the paper sensor on the paper stop, the trap doors will open and the sheet will fall down onto the conveyor belt. This is repeated until the wanted numbers of sheets in the volume is reached, then the conveyor belt will move the stack a short distance. The different volumes will then be separated on the conveyor belt. If the sheet for some reason does not arrive at the paper sensor within a certain time after the sheet is cut, the SW2 stacker will send an alarm signal back to the printer, and the printer will stop. There is another sensor at the end of the conveyor belt that will detect if the belt is full. This will also stop the printer. Eject motors Full belt sensor Paper sensor...

BRAILLO B 650 SW2.1 Eject mechanism adjustment The eject motors will run with two different speeds, Idle and Eject. The ‘Idle’ speed is slow with low torque, and ‘Eject’ is fast with higher torque. These two speeds can be individually adjusted on the two potensiometers inside the control cabinet. Turning clockwise gives higher speed. Eject Idle adjustment adjustment...

Page 129: Roll Unwinder
BRAILLO B 650 SW2.1 ROLL UNWINDER Description of functions The Roll Unwinder’s main function is to automatically supply the printer with the correct amount of paper. This is done using a laser sensor that sences the distance down to the paper. If the distance is getting shorter, the RU will feed paper faster, and if the distance is getting longer it will feed slower. If the printer stops, the paper will also stop completely. The feeding is done by leading the paper in between two rolls, where one has a built-in motor. The other roll is pressing against the motor roll by a pneumatic cylinder. When the paper feeding stops, the pressure on the pneumatic cylinder is released. Laser On/Off switch distance sensor...

Page 131: Escape-Sequences
BRAILLO B 650 SW2.1 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. This makes it possible to have different codes (read; escape-sequences) stored in a document. So, when the document is sent to the printer, these codes are sent first and the printer sets itself in the correct mode and format automatically. Note! When the printer receives an escape-sequence, it will have first priority. This means, re- gardless of the setting made before and regardless what the operator panel dictates, the most recent escape-sequence will take precedence. Note! Escape-sequences should be placed at the very beginning of the first page on the sheet, (e.g. page 1, 3, 5, 7 ...). However, a software form feed can be placed wherever needed. (If...
Page 132 BRAILLO B 650 SW2.1 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.
