Tips for printing on single sheets
There are a few things you should know about printing on single
sheets as opposed to continuous paper. When you print on single
sheets, you may notice that your printer prints the first page of
your file correctly but then prints too low on the next page, or
that it prints the last few lines from one page onto the next.
These differences in print position are easy to adjust; you can
simply change some of the settings in your application program as
described below to get the right results.
1.
When you install an application program, it normally asks you
what printer you are using. Make sure you choose the correct
printer. See Chapter 1 for the right printer to choose.
2.
Many programs include an option to set the maximum lines per
page. If your program has a lines-per-page setting and you are
using standard 8½ X 11-inch paper, set the lines per page to
61.
Note: To find the right lines-per-page setting for paper that is
not 8½ X 11, create a test document using your application
program. Set your top and bottom margins to 0 and then create
a file of numbered lines from 1 to 66. When you print your file,
notice the last number printed on the first page. This is your
maximum lines-per-page setting.
3. If your program doesn’t have a lines-per-page setting, try
decreasing the top margin or increasing the bottom margin, or
both, until you get the results you want.
4.
You can also try adjusting the form length setting. For a
standard 8½ X 11-inch page, try setting the form length at 10
inches.
5.
Some programs also let you indicate whether you are using
single sheets or continuous paper. Make sure you choose single
sheets.

Setting Up the Printer
Choosing a Place for the Printer
When selecting a place to set up your printer, be sure to keep the
following in mind:
l
Place the printer on a flat, stable surface.
Place the printer close enough to the computer for the printer
cable to reach.
lLeave adequate room around the printer to allow for easy
operation and maintenance.
CAUTION: Avoid locations that are subject to direct
sunlight, excessive heat, moisture, or dust.
Use a grounded outlet; do not use an adapter plug.
Avoid electrical outlets controlled by wall switches or
automatic timers. Accidental interruption of power can wipe
out information in the memory of your computer or your
printer.
Avoid outlets on the same circuit with large motors or other
appliances that might cause fluctuations in line voltage.
Keep the entire computer system away from potential sources
of electromagnetic interference such as loudspeakers or the base
units of cordless telephones.
Setting Up the Printer
1-3
Choosing a Place for the Printer
Note: If you plan to use a printer stand, follow these guidelines:
Use a stand that supports at least 11.6 kg (25½ lbs), which is
twice the weight of the printer.
Never use a stand that tilts the printer at an angle of more
than 15 degrees from horizontal. If you install a cut-sheet
feeder, keep your printer absolutely level.
If you position the paper supply below the printer stand, make
sure that you allow enough clearance (25 mm or 1 inch) to
keep the paper from catching on the underside of the stand.
Also see that the distance between the stand’s supports is at
least
280
mm
(11
inches), to accommodate any paper size you
may use.
Position your printer’s power cord and interface cable so that
they do not interfere with paper feeding. If possible, secure the
cables to the printer stand.

Setting Up Your Application Software
Most application programs let you specify the type of printer you
are using so that the program can take full advantage of the
printer’s features. Many of these programs provide an installation
or setup section that presents a list of printers.
Choosing from a menu
Because the family of Epson printers shares a great many
commands, you can use an application program even if it does not
list your printer on its printer selection menu. If your printer is not
listed, choose from the following list. (The printers are listed in the
order of preference.)
If none of these printers is listed, select the first one available on
the following list: LX, FX, EX, RX, MX, Epson printer, Standard
printer, Draft printer.
To use all of the features of the printer, however, it is best to
choose a program with one of the LX printers on its menu. If your
program does not list one of these printers, contact the software
manufacturer to see if an update is available.

DIP switch functions
This section describes the different features you can control with
the printer’s DIP switches.
Character spacing
DIP switch l-l controls the character spacing. If this switch is off,
the printer prints with character spacing of 10 cpi (characters per
inch); if it is on, the printer prints with character spacing of 12 cpi.
This is 10 cpi printing.
ABCDEFGHIJKLabcdefghijkl
This is 12 cpi printing.
ABCDEFGHIJKLabcdefghijkl
Shape of zero
When DIP switch l-2 is on, the printer prints slashed zeros (8);
when off, the printer prints open zeros (0).
Page length
DIP switches l-3 and l-4 control the page length. You can select a
page length of
216 mm (8.5
inches),
279
mm
(11
inches),
296
mm
(11.7 inches), or 305 mm (12 inches).
Using the Printer

Setting
the DIP Switches
Short tear-off
When you are finished printing (when the printer receives a full
page of data or a form feed and then no more data for three
seconds), this feature automatically feeds the perforation of
continuous paper to the tear-off edge of the printer cover so that
you can tear off the last sheet. When you resume printing, the
paper feeds backward to the loading position. To use this feature,
set DIP switch 2-l to off and load continuous paper. Moving the
paper release lever to the single-sheet position disables the short
tear-off function.
Adjusting the short tear-off position
1.
Make sure that the short tear-off feature is turned on and that
the paper is in the short tear-off position.
2.
Press and hold the ON LINE button until the printer beeps
once and the ON LINE light begins blinking.
3.
Press the FORM FEED button to feed the paper forward or the
LINE FEED button to feed it backward.
When you resume printing, the ON LINE light stops blinking and
the printer remembers the new tear-off position even after you
turn off the power.
Skip-over-perforation
If DIP switch 2-3 is on when you are using continuous paper, the
printer leaves a 25.4mm (one-inch) space between the last line on
one page and the first line on the next page so that the printer can
skip over the perforation. Because most application programs take
care of the top and bottom margins do not turn on skip-overperforation unless your program does not provide these margins.
3-8Using the Printer
Selecting Typestyles
You can produce a wide range of typestyles by combining different
character fonts, widths, and other enhancements. You can select
typestyles using the SelecType feature on your control panel, the
DIP switches, or software commands.
Character fonts
The printer has three fonts: draft, NLQ Roman, and NLQ Sans
Serif. The draft font uses fewer dots per character to allow highspeed printing, which makes it ideal for rough drafts and editing
work.
NLQ Roman and NLQ Sans Serif are Near Letter Quality fonts.
Near Letter Quality produces nicely formed characters suitable for
most documentation needs.
To select the draft font, press the DRAFT (LINE FEED) button when
the printer is on line. When you select the draft font, the beeper
sounds once.
To select the NLQ font, press the NLQ (FORM FEED) button when
the printer is on line. When you select the NLQ Roman font, the
printer beeps two times. When you select the NLQ Sans Serif font,
the printer beeps three times.

Condensed mode
You can use the condensed mode to change the character size. In
the condensed mode, characters are approximately 60% of the
width of normal characters. You can condense both 10 and 12 cpi
in draft mode but not NLQ.
To select or cancel condensed mode, press the CONDENSED
(LOAD/EJECT) button when the printer is on line. When you select
the condensed mode, the printer beeps once. When you cancel the
condensed mode, the printer beeps twice.
