OPERATION 1. Switches and Indicators There are three switches and four indicators (green LED’s) on the control panel and one power switch on the right side of the Printer case. In this section, panel operating procedures are covered in sufficient detail for the user to become familiar with the Printer.
FF SW: (Form Feed) LF SW: (Line Feed) When this switch is depressed once, the paper is advanced vertically to the next Top of Form position. This switch must be depressed while the Printer is OFF-LINE. Otherwise, the form feed operation will not be carried out.
1.3. Printer initial check Take the following steps and become familiar with the Printer. -38 -.
2. Buzzer The buzzer is located inside the Printer case, and sounds for about one second when the Printer receives BE L code (<O7>H). (See page 66 for the BE L code.
(2) When the Printer falls into paper-out status, it is automatically put in the OFF-LINE state and paper advancement can be performed by depressing the LF switch. After setting new paper in the Printer, depress the ON LINE switch so that the Printer may resume operation.
5. Setting of DIP Switches In order to suit the user’s specific requirements, desired control modes are selectable by the two built-in DIP switches. The DIP switches (SW1 and SW2) located on the control circuit board of the Printer are as shown in Fig.
Tip the printer right side up again. Gently loosen the upper case. Lift up the cover from the left side. And then pull out the wires hooked to the control panel on the right.
See the inside of the printer before you set the switches. The printer consists of a printer mechanism, a controller, a transformer and filter circuit board, and a control panel.
Position the printer as shown in Fig. 53. There are two “DIP” (DUAL IN-LINE PACKAGE) switches in the HMTP board. (See Fig. 54.) The switches set to the left are ON . . . to the right are OFF. (See Fig. 55.) Each switch No. of the DIP switch functions as described below.
5.1. Setting of DIP Switch No. 1 The DIP switch No. 1 consists of the following 8 pins. A summary of the functions of the respective DIP switch pins and their preset conditions at the time of shipment are shown in Table 2. Table 2 Functions and Conditions of DIP Switch No.

WHAT IS THE MX-80 TYPE II? This chapter describes the MX-80 Type II from the viewpoint of hardware and software. The contents of the chapter are; 1, What is a dot matrix printer? 2. Definitions of some terms often used. 3. Control codes in the text mode 4.
The dot matrix printing method allows a printer to easily form any desired character. It has a print head that contains 9 needles vertically and can create distinctive characters like with typewriter. In that sense it is one of the ke y features that the printer has.
(2) Character and line spacing Line spacing means the pitch from the top of dots that form a character on a line to the top of dots on the next line. It is absolutely necessary to separate characters vertically for ease in reading each sentence. Most typewriters and printers have a switch or lever to change the line spacing (1/6” or 1/8”).
If you are already familiar with the above terms, skip these paragraphs. (1) ASCII code Characters in computer systems are represented by groups of bits. The various groups of bits that represent the set of characters that are the “alphabet” of any given system are called a “coding system,” or simply “code.
(3) “+” symbol You will see “+" symbol often in the explanation or description of control codes from now on. This symbol is used for legibility only and may not be input in your actual program. (4) 2, D (or Dec.) and H (or Hex.) ( ) 2 , ( ) D and < > H respectively represent binary, decimal and hexa - decimal numbers.
(4) Other codes DC1, DC3. . ESC8. ESC9. . BE L ...... . BS ....... . NU L ...... . ESC K, ESC L Selection or deselection of the printer . Selection or deselection of the paper end detector . Bell Back space . Null Access code to Bit Image mode (described later).
NOTES: 1. The Top of Form is determined when the POWER switch is turned on or the INIT signal is applied. 2. If the form length per page is not set, one page length of form is regarded as 66 lines with the DIP switch pin 1-2 on the control circuit board set in the OFF position or 72 lines with the DIP switch pin 1-2 set in the ON position.
(3) ESC Q + n The print column width can be specified by inputting ESC Q + n code. “n” represents the print column width to be specified in character size at the time of input.
(4) ESC A + n (for setting amount of line spacing) This code specifies the amount of line spacing in the Line Feed, provided that (n ) D must satisfy the condition: (Decimal).
(5) ESC 0 Input of the ESC 0 causes the subsequent line spacing to be set at 1/8 inch. (6) ESC 2 Input of the ESC 2 causes the subsequent line spacing to be set at either 1/6 inch or 1/8 inch depending on the initial set condition of the DIP switch pin 1-1.
(9) FF (Form Feed) See paragraph 3.1 (4) above. (10) ESC C + n (n # 0), ESC C + [0] H + m (for setting form length) The “ESC C t n” code specifies the form length which is determined by the number of lines where the value of “n” is a positive number and must not exceed 127 lines).
(12) ESC 0 This code cancels the skip-over perforation set by the ESC N + n code. 3.3. Character designation codes (1) SO (Shift Out) (for enlarged characters) When the SO code is input, all data that follows it in the same line will be printed out in enlarged (double width) characters.
(2) SI (Shift In) (for condensed characters) When the SI code is input, all data that follows it will be printed out in condensed characters. This code is cancelled by the input of “DC 2” code.
(7) ESC E (for emphasized characters) The ESC E code causes the Printer to print emphasized characters. Emphasized printing gives the character a stronger impression on the paper. This code can be input in any column position on a line, but all characters on the line containing ESC E code are printed out in emphasized characters.
3.4. Other codes (1) DC 1 (Device Control 1) The DC 1 code places the Printer in the Selected state. It enables the Printer to receive data. With the Printer in the Selected state, if the DC 1 code is input during data transfer, all data stored before the DC 1 code is ignored.
(7) NUL (Null) The NUL code is regarded as the termination for tabulation setting sequence. The lack of the NUL code would cause incorrect data printout. (8) ESC K Input of this code in the Text Mode causes the Printer’s operation mode to be converted from Text to Normal-density Bit Image.
4.1. Normal-density bit image mode setting by ESC K + n l + n 2 To convert the printer’s operation mode from Text to Normal-density Bit Image, the “ESC K + n I + n 2 ” code must be input. (Here, the sign “+" is inserted for the purpose of legibility only and should not be input in actual operation.
(Ex. 4) Bit image data transfer by standard BASIC program To check for proper conversion to the Normaldensity Bit Image mode, execute the following program.
4.2. Dual-density bit image mode setting by ESC L + n 1 + n 2 When the ESC (<1B > H ) and L (<4C> H ) codes followed by data n l and n 2 ar e input, the printer’s operation mode is converted from Text to Dual-density Bit Image.
4.3. Relationship between data and dot wires Fig. 68 shows the relationship between the Bit Image data and the dot wires in the print head. You can control arbitrary 8 dot wires in the print head. If a bit is “1," the print head fires. If a bit is “0,” the print head does not fire.
4.4 How to obtain n 1 and n 2 In the Type II Printer, you have send the number of data by n 1 + n 2 in hexa- decimal numbers following the ESK K or ESC L.
4.5. Programming examples (1) Dual-density bit image printing Fig. 65 Example of Graphic Pattern Formation NOTE: The most significant bit (MSB) of the bit image data corresponds to the dot wire at the uppermost position. For example, to print a graphic data as shown in Fig.
(2) Normal-density bit image printing -74-.
(3) Difference between ESC K and ESC L The normal-density mode is accessed with ESC K. The dual-density mode is accessed with ESC L. Fig. 66 Normal-Density and Dual-Density Modes NOTE: Print alignment under the friction feed. EPSON is carefully applying printer mechanisms of better quality for MX-80 Type II and MX-80 F/T Type II.
