Introduction

Congratulations for selecting the TRS-80

DWP-510. We think it's

one of the best medium-cost,

high-quality

printers

available

for

microcomputers and it

should provide

you

with

years of reliable service.

With

a

simple change of

print wheels, the DWP-5 10

can provide print-outs

in

a

variety of font styles.

Other

special features of the DWP-510

include:

®

Selectable print pitch

(characters per inch). The pitch

can be specified via the

DWP-510 front

panel switches

or, for maximum

flexibility, via program control.

•

Tractor Feed

(optional/extra) paper

handling for fanfold

paper, or Friction Feed

(standard) paper

handling for

single-sheet or

fanfold paper.

®

A Self-Test feature that

lets you see if the

Printer is operating

properly before you

begin printing.

•

An Out-of-Ribbon

Sensor

that

automatically stops

printing when the

ribbon runs out.

•

Special

Line Feeds

(1/48", Reverse, etc.) for

special printing

applications.

and much

more!

This

manual will:

®

Describe the DWP-5 10 to you.

®

Show you how to set

it

up.

•

Describe how to use

the Printer in a

variety of printing

applications.

To Install the Print

Wheel:

1. Remove the ribbon cartridge from

the carriage by gently lifting the ribbon cartridge straight up.

2. Grasp

the two green handles (which are closest

to

the platen)

between your thumb and forefinger and gently tilt

the carriage toward

you.

3. Hold the print wheel

by the green hub. When the print wheel is properly

installed, the hub will be toward the

paper.

4.

Position the red

dot

(on

the back of the print wheel, opposite the

hub) so that it corresponds

to

and fits into the

open notch on the carriage. (Match

the red on both the hub and the notch.)

5. Push down on the

hub

until

the wheel clicks into place. The

green hub should

be

all

the way down.

6. Grasp the

two green handles (which are closest

to the platen) between your

thumb and forefinger and gently tilt

the carriage

away from you; firmly press

the carriage down into

its

original

position.

7. Replace or reinstall

the ribbon cartridge.

To

Remove

the Print

Wheel:

1. Remove

the ribbon cartridge.

2. Tilt

the carriage back as described

above.

3. Grasp the green hub

of the print wheel

and

pull

up. For easier removal,

gently

twist

the

wheel back and forth

while pulling it

up.

Ribbon

Cartridge

Installation/Removal

Radio Shack

carries

two

ribbon

cartridges for the DWP-510—

a high-quality

carbon ribbon

(26-1419) and

a

long

life nylon

ribbon

(26-1449). No matter which

ribbon

you choose, you'll find

that they're both

easy to install and

remove.

Note: When

the

carbon ribbon (26-1419)

runs

out, the printer

detects

the end of

the

ribbon and stops printing.

The nylon ribbon (26-1449)

is

an endless loop,

so this will

not happen.

To Install

a Ribbon

Cartridge:

1

.

Before installing

the cartridge,

remove all slack

in the ribbon

by

turning

the green

knob on the cartridge

in the

direction indicated

by

the

arrow (clockwise).

2. Position

the cartridge

so that the ribbon

slides into

position

between

the print wheel

and the plastic

card guide;

the

tabs on the cartridge

should line

up with the green

claws on

the carriage.

3.

Press

down on

the cartridge

and snap it

into place.

4.

Turn

the ribbon feed knob

1/4

to 1/2 turn clockwise

until

the cartridge

locks

down.

To Remove

a

Ribbon

Cartridge:

1

.

Gently press

the green

carriage claws

away from

the cartridge

tabs.

2.

Lift up on

the cartridge.

Be careful

not to

catch the ribbon

on the

print wheel.

Paper Loading

You can use either fanfold computer paper or single-sheet typewriter paper with the DWP-510.

If you're using fanfold paper, you'll find it most efficient

to

use the optional/extra DWP-510 Bidirectional

Trac-

tor Feed unit (26-1447).

Friction

Feed Paper Loading

1

.

Gently pull

the paper bail away from the platen.

2.

Set the

platen pressure lever toward

the

rear

side of the Printer (pressure

ON).

3. Insert the paper behind the platen and turn the

platen manually(turn

the

paper advance

knob) so

that the paper

advances past the card guide.

4. Set the

platen

pressure

lever

toward the front of the

Printer (pressure OFF)

so

that the paper can move

freely

back and forth.

5.

Align and position the paper at the

left margin.

6.

Hold

the

paper in position and move the platen pressure lever back toward the rear side of the

Printer (pres-

sure ON).

The paper will

no

longer

move

freely.

7. Lower the paper bail so that it is against the

paper.

8.

Position the paper manually to the first line of printing

by

turning the

paper advance knob.

Note: Be sure the Copy Control

Lever

is set to 1

unless you're using multiple form paper. If the Printer runs out of

paper, no

out

of paper signal will

be

sent to the computer; the Printer will continue

printing

on the

platen.

If this happens, immediately turn the ON-LINE/OFF-LINE

switch

to

OFF-LINE; after loading more pa-

per, return

this switch

to ON-LINE.
