IMPORTANT You have just bought the best printer, so be sure to use only the ribbons recommended for it. Original OKI ribbons are the only ones that the manufacturers recommend. Ask for them by name. Please remember that if you buy any other ribbon your warranty may be invalidated. Purchasing inferior ribbons really does not make sense. They do not last as long. What is more, they are prone to shredding, which can cause damage to your printhead. Any short term savings on cheap ribbons are quickly lost.

IMPORTANT The wires in this mains lead are coloured in accordance with the following code: GREEN AND YELLOW BLUE BROWN EARTH NEUTRAL LIVE As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug — PROCEED AS FOLLOWS: The wire coloured GREEN AND YELLOW must be connected to the terminal in the plug marked with the letter E or by the safety earth symbol or coloured GREEN or GREEN AND YELLOW.
Chapter 1 Setting Up Your Printer Your new OKI printer is packed in a protective container along with this manual and some extra items you will need. These items include: Paper separator AC cable Platen knob (fitted) OKI MIC INE ROL 9 PIN 280 PRIN TER NLQ PITCH ALA SEL LINE D FEE RM POW ER Y UTILIT HSD 10 12 17 Ribbon cartridge ECT TOF . SET M FOR D FEE 1. Do not plug in your printer until the following steps have been completed. 2.
3. Remove the carriage shipping restraint that keeps the print head in place. ➡ Carriage shipping restraint 4. Gently slide the print head to the middle of the printer or to the lefthand side so that it is away from the rollers on the column indicator bar.
5. Place the black ribbon cartridge on the ribbon cartridge holder. The easiest method is to tilt the back of the cartridge so that it slides into the area of the plate that is nearest the front of the printer, then lower the top of the cartridge (where the plastic ribbon shield is located) over the print head. The tabs on both sides of the cartridge should align perfectly with the inserts on the print head plate. Important: Only use genuine OKI ribbon cartridges in your printer.
6. Press gently on the cartridge until you feel it snap into place. To remove the ribbon cartridge, make sure the print head is moved away from the edge of the platen, then grasp the cartridge on both sides of the print head and lift up. 7. The three-position blue lever located to the left of the ribbon cartridge is used to adjust the print head gap for single or multi-part paper. When single part paper or two part paper is in the printer, slide the blue lever forwards towards the print head.
8. The platen knob should already be fitted to the right hand side of the printer. However, if this is not the case, or if it has been removed for any reason, align its slot with the spigot on the platen shaft. 9. Try running a self test to make sure your new printer is working correctly. Insert a piece of computer paper (with sprocket holes) or a single sheet of typing paper into the printer as you would insert it in a typewriter. If you are unfamiliar with typewriters, here is the method: a.
c. Close the paper release lever. d. Turn the platen knob clockwise away from you to pull the paper around the platen and behind the column indicator bar. e. Move the column indicator bar back on to the platen so that the rollers rest on the paper you have just inserted. 10. Advance the paper, using the platen knob, until 1 inch of paper appears above the column indicator bar. 11. Replace the access cover: a.

The following test pattern will be printed, beginning with a printer revision number that is followed by a rolling character pattern .
18. To stop the test, press the SELECT button or turn the power switch OFF. After the printer has shown that it is functioning correctly, it is ready to be connected to your computer using an interface cable. If you do not have one, see your computer dealer or, if you have the equipment and the technical expertise, make your own cable using the instructions in Appendix C.
Connecting to your computer You will need either a parallel or serial interface cable to connect your computer to your printer. Before you connect the cable, make sure both printer and computer power is OFF. Connecting a Parallel Interface 1. Insert the 36-pin plug into the appropriate socket on the rear of the printer.
2. Snap the two wire locking tabs on to the plug. 3. Insert the other end of the cable into your computer. You may also connect it to another peripheral device, such as a disk drive, if your equipment is designed for daisy chain connection. 4. Turn on the equipment and try the one line BASIC program shown below, using the proper print statement for your computer (the example uses LPRINT). Make sure you have paper and ribbon in the printer. 5. Type: LPRINT “EVERYTHING’S OKAY” and then run the program.
If it is overprinted, make a small adjustment to the printer switch settings so that a line feed is automatically inserted at the end of a line. (See Page 1-12 for details.
Setting the internal DIP switches Before altering the settings of the eight DIP switches, please read the instructions on Page 1-14. These DIP switches are under the small cover on the top of the printer. They allow the selection of a specific language and to make the printer meet the requirements of your computer. This section describes the switches and their factory settings.
Switches 1 to 5 work in combination to select a foreign language (or computer character set). The following table shows the correct switch settings for all available languages.
It is recommended that you set the printer for the language or character set you use most. You can use a program command (see Page 3–9) to change to another language within a document, so it is not necessary to change these switch settings if you use more than one language. Switch 6 is the automatic line feed selection. Before shipment, it is set to OFF. If you discover that your text is being overprinted, it may be because your computer does not send a line feed at the end of a line.

Chapter 2 Operating Your Printer Buttons, levers and indicators Before using your printer, it is worth familiarising yourself with the buttons, levers and indicators on the printer and to understand the various methods of loading paper. The front panel of the printer has six buttons, two of which were briefly introduced in the setup procedure. In addition, there are nine indicator lights that show the status of the printer, mode and pitch selected.
Hex mode generates data rather than text, and a sample is shown below. To terminate this mode, switch the printer supply off and on again. Switching on the printer supply whilst holding down the SELECT and LINE FEED buttons will generate a rolling ASCII character display. Pressing the SELECT button stops this test. A sample is shown below.
Release and then press the TOF SET button to record the position, then reselect the printer by pressing the SELECT button. 17.1 character per inch can be selected by holding down the TOF SET button when switching the printer supply on. SELECT Indicator: Works together with the SELECT button. Lights when the printer is selected (ready to receive data from the computer). It is not lit when the printer is deselected or during self tests.

PITCH Button: This button allows manual character pitch selection. The appropriate lamp lights upon selection. The lamps also light as software changes are implemented, for example, normal to condensed. MODE Button: Similar function to above, but this refers to the print quality selected: NLQ, Utility or High Speed Draft. The levers on the printer allow you to adjust the paper.
Paper loading Three types of paper can be used with your printer: • Single sheet paper — with/without the optional cut-sheet feeder • Roll paper — using the optional roll paper stand • Fan-fold paper — with without the optional tractor feed unit. Illustrations on the installation and use of the above mentioned optional extras follow later in this chapter. When using fanfold paper, adjust the distance between the sprocket pins at the ends of the platen to correspond to the holes in the paper.
7. Turn the platen knob to advance the paper until it appears in front of the platen. Paper guides Column indicator bar Paper release lever Platen knob 8. Lower the column indicator bar. 9. Use the platen knob to advance the paper to the first printing line. 10. Replace the access cover. Bottom Feed Paper Loading 1. Place the printer on a slotted printer stand, carefully aligning the slot in the stand with the opening in the base of the printer. 2. Place the box of paper under the printer stand. 3.
➡ 6. Slide the paper up until it appears in front of the platen. 7. Lower the column indicator bar. 8. Use the platen knob to advance the paper to the first printing line. 9. Replace the access cover.
Loading single sheets Your printer can accomodate single sheets of 216 by 297 or 355mm (8.5 by 11-inch or 14-inch) paper. Only one copy, with no carbons, can be printed at a time. Remove the tractor feed unit and any other accessories before using the paper separator. Operation 1. Place the paper release lever in its closed (rear) position. 2. Switch the printer OFF-LINE (press the SELECT switch). 3. Close the paper bail lever (To its rearward position). 4.
Line mark Cut sheet guide NOTE: When letter-size paper is used, set the cut sheet guide to the line mark on the paper separator. 80-character width text (10 CPI) is then positioned centrally on the paper. 6. Insert a single sheet along the cut sheet guide until it reaches the pinch roller. Be sure to keep the paper inside the platen ends otherwise the built-in sprocket pins will tear it. 7. Open the paper bail lever by pulling it towards the front of the printer.
Chapter 3 Programming Now that you are familiar with the outside of the printer, you can begin printing documents using the default settings of the printer, that is, the kind of printing your printer is set up to do when you turn it on: Utility Mode* 10 characters per inch 6 Lines per inch Horizontal tabs at every eighth character Vertical tabs at one inch intervals This may be all you ever need. If you plan to print tables, charts, graphics, or documents with indented text, subscripts, superscripts, etc.
Skip Over Perforation: If you use fanfold paper with your printer, you may need to use this command to instruct the printer to automatically advance the paper over the perforations. Character Pitch: You can change from 10 to 12 or 17.1 characters per inch and you can also double the character width (10 characters per inch to 5 characters per inch, 12 characters per inch to 6 characters per inch and 17.1 characters per inch to 8.5 characters per inch).
The printer will not do certain things unless you specifically tell it to. You instruct the printer to change the way it prints by sending special codes through your computer. When you write a program, you include the codes for printing features you want in your program. In BASIC, for example, include them in an LPRINT statement. Basic Programming If you are familiar with programming, skip this section and go straight to the control codes.
Computers cannot understand letters. They use only numbers, more specifically, binary numbers (1s and 0s). When carrying out an LPRINT command, the computer sends the printer a code number for each character (letter, symbol, punctuation mark) within the quotation marks. As the printer receives each number, it prints the dot pattern associated with that number. The American Standard Code for Information Interchange (better known as ASCII) is the standard code used by computers.
Let us try a few, starting with the ASCII non-printable code US. When the printer receives the SO command, it will print the next data with double width. 10 LPRINT “HELLO” 20 LPRINT CHR$(14); “HELLO” Now run the program. This is what you should get: ASCII code SO is non-printable, so you must use the decimal or hexadecimal form of the command within a CHR$ statement. Nothing in quotes will work.
The second time, the first line is printed standard width. Because the SO command is not in effect by the end of a line. To return to standard size printing (10 characters per inch) you have to put in CHR$(20), like this: 10 LPRINT“HELLO” 20 LPRINT CHR$(14);“HELLO”;CHR$(20); “ _ _ _ HELLO AGAIN” Note: _ means space.
If you have a Software Package Software packages make the printer’s special features, such as smaller type fonts, subscripts, underlining, etc., much easier to use. To add the features to your package, read your software documentation for instructions, paying particular attention to any limitations—for example, some software packages let you select a printing feature for an entire document but do not allow you to change features within a document.
If your computer is equipped with BASIC, you have an alternative to selecting features. After you load BASIC, run a simple one or two line program telling the printer to change a feature(s). Without turning the printer off, load and run your software package. For example, suppose you wanted to print at 12 characters per inch: 1. Load BASIC 2.
Programming the printer For each printing feature explained in this chapter, three different forms of each code are listed as follows: ASCII ESC 1 Standard abbreviation in ASCII-used for reference Decimal Hexadecimal 27 49 Standard presentation of Decimal Code. A variation of the same command is CHR$(27);CHR$(49) 1B 31 Hexadecimal code used by some software packages to enter printing commands.
Horizontal Tabulation ASCII Decimal Hexadecimal ESC D 0 27 68 0 1B 44 00 Horizontal tabs are set at every 8th character when power is first switched ON. To eliminate the tab settings, use the ESC D 0 command. Horizontal Tabbing ASCII Decimal Hexadecimal HT 9 09 Advances to the next tab position which occurs every 8th character. The command is ignored if it exceeds the right margin or the maximum number of settings.
Line Spacing The default line spacing for the printer is 6 lines per inch. This means that when the printer power is turned on, the spacing from the bottom of one line to the bottom of the next line on the same page is automatically set to 1/6 inch. This is also the normal spacing of a standard typewriter. The line spacing can be changed to 8 lines per inch to fit more lines of printing per page, and for special effects, you can also vary line spacing in multiples of 1/72 or 1/126 inch.
The ESC 2 command implements the line spacing set by the ESC A command. Should no ESC A command precede the ESC 2 command, the default line spacing (6 LPI) will be activated by the ESC 2 command. Fine Line Spacing ASCII Decimal Hexadecimal ESC 3 n 27 51 1-255 1B 33 01-FF The ESC 3 command is a user-selectable line space setting command that lets you choose a setting in increments of 1/216 inch.
If the multiples specified in your ESC 3 or ESC J statements are not evenly divisible by 3, fine line spacing may be slightly more or slightly less than you specified. If the number you selected leaves a remainder of 1 when it is divided by 3, spacing will be slightly less than specified. If the number you selected leaves a remainder of 2, spacing will be slightly more than specified. When the number you select is evenly divisible by 3, fine line spacing is always exact.
Form Feed ASCII Decimal Hexadecimal FF 12 0C Prints the data in the print buffer, returns the carriage, then advances the paper to the top margin of the next page. Note: (TRS-80 owners only.) This command is not valid with your computer.
The character size switches to 10 characters per inch (CPI) after the printer receives the DC2 command. The character size becomes 12 CPI when the ESC: command is received and 17.1 CPI when the SI command is received. Note: When the power is turned on while the TOF switch is depressed, the printer is set to 17.1 CPI. You can also set the printer to 17.1 CPI at power ON by setting internal switch 2 to the condensed print mode. The printer will print in 17.
10 20 30 40 50 60 70 LPRINT CHR$(18);“PICA pica 10 cpi” LPRINT CHR$(27);CHR$(58);“ELITE elite 12 cpi” LPRINT CHR$(15);“CONDENSED condensed 17 cpi” LPRINT CHR$(18);“Back to 10 cpi” LPRINT CHR$(14);“Double pica” LPRINT CHR$(27);CHR$(58);CHR$(14);“Double elite” LPRINT CHR$(15);CHR$(14);“Double condensed” Underlining ASCII Decimal Hexadecimal ESC - 1 (n: odd) 27 45 49 1B 2D 31 ESC (n: even) 27 45 48 1B 2D 30 Use the ESC - command to start underlining a word or group of words.
Underlining under the spaces designated by horizontal tabs is also available.
If you want to print subscript characters (characters appearing below the normal print line), use the ESC S1 command before entering the characters. To return to printing on the normal print line, use the ESC T command. Superscript and subscript characters are printed in normal characters. 10 LPRINT “This is ”; 20 LPRINT CHR$(27);“S”;CHR$(0);“superscript” 30 LPRINT CHR$(27);“T”;“This is ”; 40 LPRINT CHR$(27);“S”;CHR$(1);“subscript” 50 LPRINT CHR$(27);“T”;“This is back to normal.
Enhanced printing provides a deeper resolution of each character because each dot contained in a normal character is doubled vertically, creating a darker impression. The ESC G command is a good feature to use for headlines and subtitles and can be used in conjunction with doublewidth characters. Emphasized printing, obtained by entering the ESC E command, causes each character to be doubled horizontally, creating a bolder image for titles, subtitles, or emphasizing word(s) within a document.
Character Sets ASCII Decimal Hexadecimal Character Set ESC 6 27 54 1B 36 II ESC 7 27 55 1B 37 I If you use Spanish for all your documents it is better to make the selection on the internal switches so that the printer normally uses that language. Cut Sheet Feeder ASCII Decimal Hexadecimal ESC EM I 27 25 73 1B 19 49 ESC EM R 27 25 82 1B 19 52 If you are printing program outputs using the Cut-Sheet Feeder, you must include the Cut-Sheet Feeder insert and eject commands.
Bit Image Graphics ASCII Decimal Hexadecimal ESC K 27 75 1B 4B ESC L 27 76 1B 4C ESC Y 27 89 1B 59 ESC Z 27 90 1B 5A Using bit image graphics, you can draw almost any kind of illustration with your printer. Bit image graphics mode enables your printer to draw almost any kind of illustration by printing a dot at any location on the page. Your IBMcompatible MICROLINE will work properly with any graphics software package designed for the IBM Personal Computer and IBM Graphics Printer.
Programming Bit Image Graphics You can also write a program that prints a graphics image directly, without transferring it from the display screen. This section explains how to do this using BASIC statements. Your printer prints graphics images in successive columns of eight dots.
ESC K ESC L 27 75 Single Density 1B 4B (hex) 60 x 72 DPI Max. dots/line 480 27 76 Double Density, half speed Max. dots/line 1B 4C (hex) 120 x 72 DPI 960 In this mode, the printhead slows down so it can print dots that overlap by about 1/2 dot width. ESC Y 27 89 Double Density, normal speed Max. dots/line 1B 59 (hex) 120 x 72 DPI 960 This mode has the same density as ESC L and prints at normal speed; however, you cannot print dots in the same row in adjacent columns.
2. Number of Columns The start graphics code is followed by two numbers telling the printer how many columns to print. For ease of reference, call these numbers n1 and n2. To find the value of these numbers, determine how many columns you want to print, then divide it by 256. The value of n2 is the integer portion of the quotient, and the value of n1 is the remainder expressed as an integer.
Example: Suppose you want to print 400 columns of graphics: n2 = 1 256 400 256 n1 = 144 If you want to print in single density graphics mode, the beginning of your statement should look like this: LPRINT CHR$(27);CHR$(75);CHR$(144);CHR$(1) n2 n1 ESC K IBM BASIC includes two functions that make calculating nl and n2 very easy: ● MOD divides two numbers and returns the integer remainder, ● FIX removes the fractional portion of a numeric expression without rounding it off.
Maximum Graphics Columns Per Line Graphic’s mode ESC K (Single Density) 480 ESC L/ESC Y (Double Density) 960 ESC Z (Quadruple Density) 1920 If the value entered is greater than the allowed maximum, the proper maximum value will automatically be entered. 3. Graphics Data The last part of the graphics statement contains numeric data that tells the printer to print dots at specific positions in each column.
Column Position Values Column Position Decimal Value Bit 128 27 64 26 32 25 16 24 8 23 4 22 2 21 1 20 Example: 64 16 8 4 1 Enter 93 as CHR$(93) If we call the number for each column C1, etc., then the complete statement looks like this: LPRINT CHR$(27);CHR$(75);CHR$(144);CHR$(1);CHR$(C1); CHR$(C2); ... ;CHR$(C400) column data col. 1 ...col.
Putting it Together Now we can work through a simple example. Suppose we want to draw two diagonal lines. As drawn on graph paper, they look like this: Step 1. Begin with LPRINT and the start graphics code for single density graphics: 10 LPRINT CHR$(27);CHR$(75); Step 2. Count the columns in the image.
Step 3. Next add the dot values for each column and insert them in the statement: 10 LPRINT CHR$(27);CHR$(75);CHR$(11);CHR$(0);CHR$(1);CHR$(2) CHR$(4);CHR$(9);CHR$(18);CHR$(36);CHR$(72);CHR$(144); CHR$(32);CHR$(64);CHR$;(128) Step 4. Now run the program. The result should look like this: If it does not, check your arithmetic and typing, then try again.
Notice that the angle is steeper and the two lines are closer together. This is because each individual column now overlaps the next one. Notice also that it prints more slowly, although with this amount of printing the difference in speed may be hard to detect.
Here is another sample program that uses a FOR-NEXT loop to print all the possible combinations of dots and spaces in numeric order: 10 20 30 40 50 60 70 80 90 REM SAMPLE 2 WIDTH “LPT1:”,255 NDOTS = 256 ‘MAXIMUM POSSIBLE COMBINATIONS LPRINT CHR$(27);CHR$(75);CHR$(NDOTS MOD 256); CHR$(FIX(NDOTS/256)); REM START GRAPHICS 256 COLUMNS FOR I=0 TO NDOTS-1 LPRINT CHR$(I); NEXT I PRlNT:REM LINE FEED A word of explanation about line 20.
You can vary the length of the graphics line by changing the value of NDOTS. Try changing the density in this program and see what happens. Save this program; you will need it later. Combining Text and Graphics You can mix normal text printing and graphics on the same line.
Printing Multiline Graphics One LPRINT statement cannot print more than one line of graphics, so you have to enter a separate LPRINT statement for each subsequent line of graphics. To illustrate this, add these lines to the SAMPLE 2 program: 40 FOR J = 1 TO 4 75 NEXT J This loop causes the LPRINT statement to be repeated four times. Here is the result: Notice that there is a space between each pair of lines.
The modified program now looks like this: 10 15 20 25 30 35 40 45 50 55 60 65 70 75 REM SAMPLE 2 WIDTH “LPT1:”,255 NDOTS = 256 REM MAXIMUM POSSIBLE COMBINATIONS LPRINT CHR$(27);CHR$(65);CHR$(8) LPRINT CHR$(27);CHR$(50) FOR J = 1 TO 4 LPRINT CHR$(27);CHR$(75);CHR$(NDOTS MOD 256); CHR$(FIX (NDOTS/256)); REM START GRAPHICS 256 COLUMNS FOR I=0 TO NDOTS-1 LPRINT CHR$(I); NEXT I LPRINT : REM LINE FEED NEXT J The result looks like this: 3 – 34 Programming
Reminders 1. Make sure you have entered column data for the same number of columns as specified by n1 and n2 in your LPRINT statement. If you enter too much or too little data, the results will be garbled. 2. You can print no more than the maximum number of columns for your graphics density mode. If more data is contained in the LPRINT statement, the excess will simply be ignored. 3.
To simplify typing the column data, you can enter the values in a DATA statement, then use a READ statement in a loop to print it. Here is a model: 30 40 50 60 70 100 . . . LPRINT CHR$(27);CHR$(75);CHR$(NDOTS MOD 256); CHR$(FIX(NDOTS/256); FOR I = 1 TO NDOTS READ C LPRINT CHR$(C): NEXT I . . . DATA 2, 4, 8, 16, 32........... This method makes it easier to check and modify your data.
Line Feed ASCII Decimal Hexadecimal LF 10 0A VT 11 0B Execution of the VT or LF command causes one line of data to be printed, and also causes the paper to advance one line. Paper Out ASCII Decimal Hexadecimal ESC 8 27 56 1B 38 ESC 9 27 57 1B 39 If you want to disable the paper out alarm (the paper indicator will not light when paper is low) enter the ESC 8 command. If you want to be signaled by the printer when paper is low or out, (this is the default setting) use the ESC 8 command.
Utility Mode ASCII Decimal Hexadecimal ESC I SOH 27 73 1 1B 49 01 The first time you turn your printer on, it will automatically print in utility mode. In this mode, the printer prints bidirectionally. This printing method increases the printer’s speed, so it prints 200 characters per second. HSD Mode ASCII Decimal Hexadecimal ESC # 0 27 35 48 1B 23 30 This printing method increases the printer’s speed, so it prints 240 characters per second.
