INTRODUCTION

Scope

This manual contains instructions reiating

to

the installation and operation

of

all

Cen-

tronics' Series 100 printers. This includes uncrating and set-up procedures, operating instruc-

tions and

other

reference information useful

to

the printer operator.

General Description

The Centronics Series 100 printers are medium speed, impact printers which use

dot

matrix techniques for character generation. Each

is

a completely self-contained unit which

includes the mechanical and electro-mechanical components, control logic, character pattern

generator, single line buffer (132 characters) and power suppiy.

Available models include:

(a) Model 101 -The basic printer, prints 132-column lines at 165 characters per

second.

(b) Model

lOlA

-Similar

to

the Model 101, but with additional features such

as

paper runaway inhibit, manual line feed switch, remote select/deselect, etc.

(c) Model 101AL -Functionally the same

as

the

lOlA,

but

uses more compact

electronics packaging.

(d) Model 101S -Prints standard O.l-inch characters

as

well

as

large-scale (e.g.,

.2, .3,

.4

and .7-inch high) symbols, using .1-inch

dot

patterns

as

building

blocks.

(e)

Model 102A -Prints at twice the speed

of

the

101

A

by

using two print

heads.

(f) Model 102AL -Functionally the same

as

the 102A, but uses more compact

electron

ics

packaging.

The model number

is

specified on a nameplate located on the back

of

the printer.

Alarm -consisting

of

a 2-second audible tone sounded

in

response to a

BELL code (octal 007) or a paper empty condition.

(2) A Form Thickness control knob (and lock knob) -located on the print head

LOADING

PAPER

1. Before

loading

paper

into

the

printer,

first lift

the

front

cover

and

open

the

gates

for

the

left

and

right

feed

units. Make sure

the

left

pin feed

unit

is

locked

in place

at

the

extreme

left

margin.

2.

Feed

paper

down

through

the

slanted

opening

in

the

top

of

the

printer.

The

paper

will

follow

the

forward

paper

pan

and

come

up

to

the

pin feed

tractors.

3. Place

the

top

sheet

in

the

paper

feed

tractors.

Make

sure

the

holes

are

aligned so

that

the

top

of

the

sheet

is

parallel

with

the

top

of

the

printer.

If necessary, loosen

the

fixing

knob

on

top

of

the

right pin feed

unit

and

move

the

unit

to

accommodate

the

width

of

the

paper.

When

properly

adjusted,

tighten

the

fixing

knob.

4. Close

the

gates

for

the

pin feed units,

then

close

Switch.

This

aligns

the

top

of

form

hole in

the

vertical

format

paper

tape,

directly

over

the

light

source

in

the

paper

2. Use

the

knob

to

adjust

the

paper

so

that

the

desired

top

line

on

the

form

is

aligned vertically

with

the

print

head.

This

adjustment

is

performed

by pulling

out

the

platen

knob

and

rotating

it in

either

direction.

Once

aligned,

each

time

a

Form

FORMS THICKNESS CONTROL

Two adjustment knobs on either side

of

the print head carriage control the clearance

between the platen and the face

of

the print head. This clearance must be adjusted according to

the thickness

of

the forms being used.

On

a Series 102 printer, the two heads must be adjusted

independently.

To adjust the print head for optimum print quality perform the following steps:

1.

Loosen the Lock knob on the left side

of

the print head.

2.

Increase the penetration

of

the print wires on to the ribbon

by

slightly turning the

Penetration Control knob.

3. Manually move the print head across the paper.

Keep

increasing the penetration until

smudging occurs.

4. Back off on the Penetration Control knob just to the point of

no

smudging.

5. Tighten the Lock knob to secure the print head

in

position.

Note

Numbers on Penetration Control knob do not

correspond

to

the number

of

VERTICAL

FORMAT

UNIT

Vertical

formatting

in

the

Series

100

printers

is

controlled

by

a

paper

tape

in

the

Vertical

Format

Unit. This

unit

is

located

on

the

upper

left side

of

the

printer

just

under

the

left cover.

The

tape

is

a standard

l-inch

wide, 8-channel, black

opaque

paper

tape.

The

sprocket

holes, located

between

Channels 3

and

4,

have a

1/10

inch

pitch

between

holes. Channel 5

defines

the

Vertical

Tab

(VT)

format

and

Channel 7

the

Top

of

Form

(TOF)

format.

The

tape

reader and

paper

feed mechanisms are mechanically linked so

that

each line feed advances

both

the

paper by

one

line

and

the

paper

tape

by

one

sprocket

hole,

on

a 6 line-per-inch printer.

Reception

of

a Vertical

Tab

code

(octal

013)

advances

the

paper

(and tape)

to

the

in

Channel 5.

For

example,

if

the

holes

in

Channel 5 are spaced six

sprocket

holes

apart,

each Vertical

tab

will advance

the

paper

six lines

(one

inch).

Similarly,

reception

of

a

Form

Feed

code

(octal

014)

or

pressing

the

TOP

OF

FORM

switch advances

the

paper

(and tape)

to

the

in

Channel

7.

As an

optional

feature

on

some

printers, a hole

in

both

channels 5

and

7 indicates

bottom

of

form

(BOF).

Detection

of

this

condition

automatically

advances

paper

to

the

top

of

the

and

TOF

indications on

tape

must

be

separated

by

at

least

one

line.

On

the

standard

paper

tape

shipped with

the

printer,

Vertical

Tab

holes

are

spaced six

sprocket

holes

apart

in Channel

5,

(corresponding

to

a

l-inch

tab)

and

Top

of

Form

holes

are

spaced

66

sprocket

holes

apart

in

Channel 7

(corresponding
