Initialization

There are three ways that the printer can be initialized (returned to a fixed set of conditions). Hardware initialization
When the power is turned on When the printer receives an INIT signal at the parallel interface (pin 31 goes LOW). Software sends the ESC @ (initialize the printer) command.
In addition, the data buffer is cleared when the printer is initialized by turning on the power or by an INIT signal. Note: The user-defined character set is not cleared when the printer is initialized.

FX - 850/1050 DOT - MATRIX PRINTER DIP Switch Functions
The tables below describe the DIP switch functions. The page numbers refer you to the page on which each printer feature is described. The shaded settings are the preset factory settings. DIP Switch I Cut sheet feeder mode When DIP switch 2-2 is on, you can use your printers optional cut sheet feeder. See Chapter 7 for more information on using a cut sheet feeder with your printer. Skip over perforation When DIP switch 2-3 is on, a one-inch margin is provided between the last line printed on one page and the first line printed on the next page. When using continuous paper, this feature causes the printer to stop printing, skip over the perforation, and then resume printing. If you adjust your loading position correctly, you can get half of the margin at the bottom of one page and half at the top of the next page. See the section on adjusting the loading position later in this chapter.
Note: Most application programs take care of the top and bottom margins. Only use skip over perforation if your program does not provide these margins

Automatic line feed When DIP switch 2-4 is on. a carriage return code (CR! causes an automatic line feed. When it is off, line feeds occur only when the printer receives line feed codes (LF). Since some computers and application programs automatically add line feeds to carriage returns, the setting you use depends on your computer and application program. Default character set When DIP switch 1-1 is on, the user-defined character set is the default. User-defined characters are maintained in printer memory even when the power is turned off, so the user-defined character set can be selected simply by setting this switch to on. However, when this switch is on, new user-defined characters cannot be defined. See Chapter 4 for more information on user-defined characters. This switch is effective only in the Epson ESC/P mode. Zero character When DIP switch 1-2 is on, the printer prints slashed zeroes (0). When the DIP switch is off, the printer prints open zeroes (0). This is useful for clearly distinguishing between uppercase O and zero when printing such items as program lists. Character table

International Character Sets
Selecting an international character set provides you with the characters used in other languages. To obtain the desired international character set, set switches 1-6, 1-7, and 1-8 according to the DIP switch table on page 3-7. The following table shows the characters that differ in each international character set.

When DIP switch 1-3 is on, the Epson Extended Graphics character table is selected. When it is off, the italics character table is selected. The Epson Extended Graphics character table contains international accented characters, Greek characters, and character graphics for printing lines, corners, and shaded areas. If you have an IBM@ computer or an IBM compatible, select the Epson Extended Graphics table when you wish to print the character graphics as they are displayed on the screen. Since the character table setting affects only half of the character table, you can
The countries numbered 8 through 12 are available only through the ESC R software command. See the Command Summary in Chapter 8. Also, in IBM emulation mode (DIP switch 1-4 on), a character set containing international characters (CG character table 2) is selected whenever any one of DIP switches 14. 1-7, or 1-8 is set to off. If all three switches are on, CG character table 1 is selected. See Appendix B. Page length When DIP switch 2-1 is on, the page length is set to 12 inches. When it is off, the page length is 11 inches. Other page lengths can be set with the ESC C and ESC C0 commands. See the Command Summary in Chapter 8. still print text if you have selected the Extended Graphics set. Also, you can still print italics if you use the proper software command. If your printer is in IBM emulation mode (DIP switch 1-4 on), the graphics characters are available no matter which character table you select.

The column heading Direction refers to the direction of signal flow as viewed from the printer. Return denotes the twisted-pair return. to be connected at signal ground level. For the interface wiring, be sure to use a twisted-pair cable for each signal and to complete the connection on the return side. These cables should be shielded and connected to the chassis of the host computer and the printer. All interface conditions are based on TTL level. Both the rise and the fall times of each signal must be less than 0.2 microseconds. Data transfer must be carried out by observing the ACKNLG or BUSY signal. Data transfer to this printer can be carried out only after receipt of the ACKNLG signal or when the level of the BUSY signal is LOW.

I Installation/Support

Software

The type of printer installed on your system must be identified for each software package. This is usually done through a setup menu. If this printer is not listed in your program, look in the printer Users Manual for the next-best model selection.

DIP Switch Settings

The default settings will usually work for most applications, but they should be checked before using the printer This will avoid unexpected results.

Serial Operation

The FX-850/1050 will be able to receive serial data with the addition of an Epson 81XX series interface option.
Cut - Sheet Feeder Operation
The page length will have to be adjusted (shortened) to 61 lines per page if your software does not properly support cut -sheet paper. There will be lines from the first page printed at the top of the second page if the page length is not set correctly.

Disabling the Buffer

An undocumented feature of the FX-850/1050 is the ability to disable the buffer from the SelecType panel. To toggle the buffer hold down the Load/Eject switch at power on. Two beeps indicate that the 8K buffer is enabled, and one beep indicates that the buffer is disabled. (Some spooler applications wont work correctly unless the buffer is disabled.)
