SelecType
You can use the SelecType control panel to choose fonts, pitches, and

remain valid even after the printer is turned off. reset, or initialized.
However, commands from your software application program
temporarily override the SelecType settings.

Cut sheet feeder mode
When DIP switch 2-2 is on, you can use your printer’s 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
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.

Note: You may need to use the ESC 6 command to print some of the
Extended Graphics characters. See Appendix 8.
Printer mode
When DIP switch 1-4 is on, the printer operates in the IBM emulation
mode. When it is off, the printer operates in the Epson ESC/P mode. In
the IBM emulation mode, DIP switch 1-3 controls the automatic carriage
return. When switch 1-3 is off, a carriage return is added to each line
feed. The functions of DIP switches 1-6, 1-7. and 1-8 are also different
when using the printer in the IBM emulation mode.

Software
Now that you've set up and tested the printer, you need to start using it
with your application programs.
Most application programs let you specify the type of printer you’re
using so that the program can take full advantage of the printer’s
features. Many programs provide an installation or setup procedure that
present\ a list of printers to choose from. If your application program
has a printer selection menu. use the instructions below.
Using printer selection menus
If your software has a printer selection menu, simply choose FX-850 or
FX-1050. If the menu does not list either of these printers, choose one of
the following. They are listed in order of preference.

If you plan to use the IBM emulation mode, choose IBM Proprinter (if
you have an FX-850). IBM Proprinter XL (if you have an FX-1050). IBM

The buttons on the control panel let you control many of the printer
settings. The control panel also has Indicator lights so you can check the
current status of the printer’s various settings.

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.
l 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.
l Data transfer must be carried out by observing the ACKNLG or

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 won’t work correctly unless the buffer is
disabled.)
