reach.
l Leave adequate room around the printer to allow for easy
operation and maintenance.
l Use a grounded outlet; do not use an adapter plug.
The illustration below shows a good printer location.
Setting Up the Printer 1-7
Choosing a Place
for
the Printer
Note: If you plan to use a printer stand, make sure it meets the
following requirements:
l
The stand must support at least 35 lb or 16 kg (twice the
weight of the printer).
l The stand must not tilt the printer more than 15 degrees from
horizontal. With a cut sheet feeder, the stand must keep the
printer level.
l If the paper supply is below the printer stand, make sure that
the paper cannot catch on the underside of the stand or on
the stand supports.
l
Make sure that the power cord and the interface cable do not
interfere with paper feeding. If possible, secure them to a
printer stand support.
WARNING:
l
Avoid locations that are subject to direct sunlight,
excessive heat, moisture, or dust.
l
Avoid using electrical outlets that are controlled by
wall switches or automatic timers. Accidental
disruption of power can wipe out information both in
your computer’s memory and in your printer’s
memory.
l Avoid using outlets on the same circuit with large
motors or other appliances that might disturb the
power supply.
l Keep the entire computer system away from potential
sources of interference such as loudspeakers or the
base units of cordless telephones.

Printer Selection Menus
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 to choose from.
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. Choose from the following list
(the printers are listed in the order of preference):
L-750
L-1000
LQ-850/950/1050
LQ-500
LQ-2550
LQ-2500
LQ-800/1000
LQ-1500
If none of these printers is listed, select the first one available on the
following list.
EX

To use all the features of your printer, however, it is best to use a
program with one of the LQ printers on its menu. If your program
does not list these printers, contact the manufacturer to see if an
update is available.

DIP Switches
By changing the settings of the two sets of DIP switches on the
back of the printer, you can control various printer features, such
as the character set and page length. These new settings become
valid when the printer is turned on, reset, or initialized.
Setting the DIP switches
Follow these steps to set the DIP switches:
1. Be sure the printer is turned off.
2. Use a pointed instrument, such as the tip of a pen, to set the
switch either on or off. The tables on the following pages give
the DIP switch functions for each setting.
The new settings become valid when you turn on the printer.

DIP Switches
Auto line feed
When auto line feed is on (DIP switch 2-4 on), each carriage return
code (CR) is automatically accompanied by a line feed code (LF).
Input buffer capacity
The input buffer stores data from your computer. If you want to
free your computer for other tasks while the printer prints, change
the setting to 8 Kbytes (DIP switch 2-5 on). Before defining user-
defined characters, however, be sure to set the switch to 1 Kbyte
(off).
Print direction for graphics
The printer ordinarily prints text bidirectionally for speed and prints
graphics characters unidirectionally for precise vertical alignment.
You can, however, change text printing to unidirectional with the
software command ESC U1. If DIP switch 2-6 is on, you can
change graphics character printing to bidirectional with ESC U0. If
DIP switch 2-6 is off, graphics character printing is unidirectional
whether or not ESC U0 is used.
Page length
DIP switch 2-1 lets you select a page length of 11 inches (27.94 cm)
or 12 inches (30.48 cm). If you are using paper that is 12 inches long,
you can set this switch on. (Factory setting is off for 11 inch paper.)
Skip over perforation
DIP switch 2-3 controls the skip over perforation function. If this
switch is on when you are using continuous paper, the printer
leaves a one-inch margin between the last printed line on one page
and the first printable line on the next page so that the printer skips
over the perforation.
Most application programs take care of the top and bottom
margins. Therefore, do not turn on skip over perforation unless
your program does not provide these margins.

If you adjust your top of form position to the proper point, you
can get half of the margin at the bottom of one page and half at the

Draft mode uses fewer dots per character for high-speed printing,
which makes it ideal for rough drafts and editing work.
Roman and Sans Serif are Letter Quality (LQ) fonts. Letter Quality
takes a little longer to print, but produces fully-formed characters
for presentation-quality documents.

Choosing a Character Table
DIP switch 1-7 selects the italic character table or the Epson
Extended Graphics character table. The Epson Extended Graphics
table contains international accented characters, Greek characters,
mathematical symbols, and character graphics for printing lines,
corners, and shaded areas.
If you have an IBM® or compatible computer, select Epson
Extended Graphics by setting DIP switch 1-7 on. You can then print
both text and the character graphics that are displayed on your
screen. Also you can still print italics using the ESC 4 command.
Samples of italics and Epson Extended Graphics are shown below.

Reloading during printing
When you print a document more than one page long using single
sheets of paper, there are two ways your software can allow you to
load a new sheet at the end of a printed page:
l If your software sends characters in a continuous stream, the
printer stops printing when it reaches the bottom of the paper.
When this happens, the page ejects and the
off automatically.
l If your software handles printing page by page, it probably
stops sending characters at the end of a page and prompts you
to insert more paper. In this case, the

Using Continuous Paper
Positioning your continuous paper supply
Here are three ways to position your printer and supply of
continuous paper.
It is also important to align your paper supply with the paper
loaded in the tractor so that the paper feeds smoothly and straight
into the printer.
Loading continuous paper
Follow these steps to load continuous paper:
1. Turn off the printer.
2. Push the paper bail lever back; then slide the print head to the
middle of the printer.
WARNING: If the printer has been used recently, the print
head may be hot. Let it cool before attempting to move it.

Attaching the paper separator
With continuous paper, you need to attach the paper separator to
avoid paper jams. First, align the pins of the paper separator with
the slots on the printer and then rest the separator on the printer.
Setting the top of form position
It is important to set the top of form position properly because this
position determines the first printable line of each page. The top of
form position remains valid until the printer is turned off, reset, or
initialized.
Follow these steps to set the top of form position:
1. Turn off the printer.

and the fall times of each signal must be less than 0.2 µs.
l 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.)

Printing enabled/disabled signals and control conditions
The table below shows the relationship between printing being
enabled or disabled, the on line/off line status, and the receipt of
the data on/off control characters, DCl, or DC3.
l While printing is disabled, character data is being received and acknowledged
so that the printer can look for another DC1 character that will allow it to resume
printing.
