Introduction
Congratulations for selecting this Tandy computer product! The DMP-130
is ahigh-density, dot-matrix printer which can perform avariety of differ·
ent printing operations. For instance, it can print:
• Proportionally spaced characters
• Monospaced characters (standard, condensed and compressed)
• Correspondence quality characters
•Italic cursive characters
•Super-/subscript
•Microfont
• Graphics standard and high-resolution
The DMP-l.30 operates in .3 modes:
• Data Processing Mode for the fastest output of program listings or data
• Word Processing Mode for letter writing or the creation of any text
documentation
• Graphics Mode for drawing pictures, figure or graphs
For word processing, you'll find the DMP-130's proportionally spaced
characters (created on avariable 11 x 18 dot matrix) can produce letter-
quality results.
If, however, you need a printout that is produced faster, monospaced
characters (created on a 9 x 9 dot matrix) are just the thing for you!
In
Graphics mode, you can use graphic data to draw just about any type
of graphic configuration you desire.
You can use 2types
of paper with the DMP-130:
• Standard 4" (IOcm) to 10" (25cm) wide computer fanfold forms with
guide holes (CaL Nos.
26-1243,26-1427,26-1403, and 26-1456)
• Standard, single-sheet typewriter paper for use as in an ordinary
typewriter
Other software-controlled features include:
•Full- or half-line feed and .3/4 or 4/5 line feed.
eSoftware-controlled form feed (from your
computer).
• Underline capability.
• Buzzer function.
• Automatic paper loading.
•Margin-set function.
• Automatic paper feed at paper end. When the DMP-130 detects the
paper end, it automatically advances the paper .3 more inches (7.5cm)
for
easier paper removal.

Description of the DMP-130 1
Carefully unpack the DMP-130, being sure to locate the ribbon and the
paper rack. Keep the empty box and packing material just in case you
ever need to transport the Printer.
It's important to become familiar with the DMP-130 before you set it up
and begin using it.

Setting up the DMP-130 2
This section will show you how to set up the DMP-130 so you can begin
using it as quickly as possible, This includes:
•Installing the paper rack
•Installing/adjusting the tractor feed unit
•Loading paper
•Replacing aribbon
• Connecting the DMP-130 to a computer
and more!
The following Start-Op Checklist is a summary of how to set up your
Printer and should be followed every time you start up the Printer not
just the first time.
EJ Find agood spot for your Printer. Be sure to consider:
• Printer should be placed on asturdy work surface.
• Length of the printer cable, which will determine how far from the
computer you can place the Printer.
• Paper takes up space, Be sure to leave enough room for smooth paper
flow.
• Do not place the Printer near noise generators such as refrigerators and
industrial equipmenL
G Be sure the POWER switch (on the right side of the Printer) is OFF,
GJ Open the Printer cover.
[2] Install continuous-form fanfold or single-sheet paper.
[2] Check the ribbon cassette, If it has not been installed, see "Ribbon
Installation/ReplacemenL"
[2] Set the print function (DIP) switches (on the rear of the Printer),
GJ Connect the AC power plug to a120-volt, 60 Hz grounded AC outlet
(220/240Y, 50 Hz, where the unit is so marked).
GJ Connect the interface cable from the computer to the Printer interface
connector.
[2] Turn the power ON and check that the POWER indicator (on the
front
panel) is illuminated,
GJ Check to see that the Printer is ready by running the self-tesL To do
this, turn the POWER switch OFF, Press and hold the LINE FEED
switch or NLQ switch while turning the power back ON. If you press

linue ulllii you press the Oi-i/OFF LiNE switch
Paper rack
Open the Printer cover Holding the paper rack upright. insert the tips of
the rack onto the supporters on both sides of the Printer, as shown,
For single-sheet printing, inst;rt the folding leg into the hole centered on
top of the case For the continuous fan-fold paper, fold the leg and lay the
rack down
You can adjust the paper guide on the paper rack Pull the left guide
upward to remove it from the rack, Then position it as you desire (within
the range allowed) and insert it fully. When using narrower paper, move
the right guide so that the left edge of the paper is within the range of the
paper guide This ensures proper operation of the paper empty switch and
also reduees the possibility of a paper jam.
l'ractor feed unit
This Printer can be used with either the tractor feed system or friction
feed system The difference is that the tractor feed system is used with
paper which has guide holes on both edges, while the paper used with the
friction feed system does not have these holes,
When you use the friction feed system, he sure to remove the tractor
When tractor is installed, the friction mechanism is release,d and the
Printer may not feed the paper properly,

1. Turn the Printer OFF,
2. Open the Printer cover and remove the paper rack,
3. Turn the paper loading knob toward you.
4. Lift the tractor feed unit from the rear, then pull it upward
5. Turn the paper loading knob away from you.

Power source
Before plugging the power cord into an AC power outlet, check the
following:
D
Printer power ON/OFF switch is set to OFF,
D Printer is not connected to the Computer yet.
Connect the AC power plug to a nO-volt, 50 Hz grounded AC outlet
Paper loading
Warning! When loading paper (single-sheet or fanfold), be sure the paper
correctly enters the paper insertion opening.
It is very important that the paper enters the DMP-130 straight. The
paper must be directly behind the Printer or paper skewing or jamming
may occur. Proper positioning of the paper guides (which attach to the
paper rack) is also important to help prevent paper jamming.
If fanfold paper is correctly loaded, it should enter between the body of
the Printer and the paper rack, Once the paper is loaded and powcr is
ON, check the ALERT indicator. Press the ON/OFF LINE switch if the
lamp is illuminated. When the lamp remains lit, the paper is probably
loaded incorrectly,
You may begin printing if the lamp does not illuminate after the paper is
loaded.
