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 familiarized with the Printer. (See Fig. 28 for the control panel.) Pow[...]

FF SW: (Form Feed) LF SW: (Line Feed) When this switch is depressed once, the paper is advanced ver- tically 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. The Top of Form position is initialized when the POWER switch is turned on or when INI[...]

Table 1 Interface Signals in Paper-Out Status When the Printer falls into paper-out status, the buzzer sounds intermittently for 30 seconds to alert the operator. After the buzzer stops, 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 o[...]

(c) Set the adequate ASCII code data to be printed. To obtain low logic level signals, connect the data transfer line required for printing (pin Nos. 2 to 9) to GND level (pin No. 33, etc.) l Example of printing’?” “Z”=[5. A]~=(0101 1010) In this case, connect pin Nos. 2, 4, 7 and 9 to pin No. 33. 5. Construction of MX-80 F/T The EPSON MX-8[...]

These control codes are recognized by the MX-80 F/T, and the Printer performs specified functions upon receipt of these codes. The following are descriptions of respective co[...]

(2) LF (Line Feed) When the LF code is input, all data in the print buffer is printed and the paper is advanced one line. NOTE: If no data precedes the LF code, or if all preceding data is “SPACE”, only paper feeding is performed. For example, if the data is transferred in the order of DATA-+CR+ LF. DATA will be printed by the CR code, and when[...]

(6) SI (Shift In) When the SI code is input, all data that follows it will be printed out in con- densed characters. This code is cancelled by the input of “DC 2” code. The SI code can be input at any column position on a line, but all characters/ symbols on the line containing SI code are printed out in condensed characters. When printing cond[...]

(10) CAN (Cancel) Upon the input of the CAN code, all data previously stored in the print buffer is cancelled. Therefore, this code is regarded as the print buffer clear command. This code clears the print buffer, but control codes (excluding the SO code) are still valid even if the CAN code is transferred. The validity or invalidity of the CAN cod[...]

Relations among the ON LINE switch, SLCT IN signal, DC l/DC 3 code and interface signals are shown in Table 9 below. Table 9 DC 1/DC 3 and Data Entry NOTES: 1. In Table 9, it is assumed that as soon as the Printer receives data. it sends back the ACKNLG signal, though this data is not stored in the print buffer. In this status, the Printer is waiti[...]

2) ESC 1 (Escape 1) Receipt of an “ESC” followed by ASCII code “1” causes the line spacing to be set at 7/72 inch. Input of the ESC 2 code or INIT sig- nal to the interface connector or turning the power off and on again causes the line spacing to return to l/6 inch. 3) ESC 2(Escape 2) Receipt of an “ESC” followed by ASCII code “2” [...]

1) ESC A+n This code specifies the amount of line spacing in the Line Feed. 1 <<n > lo<85 (Decimal): “n” is, a binary number. “n”=1 is equivalent to 1/72 inch paper advancement. Since the distance between any two dot wires of the print head is 1/72 inch, any line spacing in increments proportional to the dis- tance between the d[...]

2) ESC B+nl+n2+. +nk+NUL (ld<n>lo<66,1dkd64,nkdnk+l) This code specifies the vertical tab stop positions. The first 64 valid tab stops per page are recognized in the Printer; subsequent tab stops are ignored. A tab stop set at a line exceeding the form length is ignored. Tab stop numbers must be received in incremental numerical order. To [...]

3) ESC C+n (ld<n>1&66) This code specifies the form length per page. The form length is determined by the number of lines (=“n”). The amount of a line spacing at this point is a predetermined numeri- cal value by “ESC A+n.” When the form length is not program- med, one page is assumed as 66 or 72 lines. Prior to setting the vertic[...]

5) ESC E 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. The speed of the head carriage reduces to 40 CPS while printing emphasized characters. 1. [DATA] lm ABCDEFGHI (CR1 m PRINT1 EIBCDEFGHI 2.
