behaviour.

 

AUTO

 ‐

laser

to

 

its

 

starting

of

 

the

to

 

the

only

  

 

Before

 

first

 

data

 

plotting,

 

check

 

the

 

AUTO/MANUAL

 

switch

 

and

 

set

 

it

 

to

 

AUTO

 

position.

 

When

 

you

 

start

 

the

 

plotter,

 

laser

 

head

 

will

 

move

 

to

 

its

 

starting

 

position

 

(left

 

side),

 

after

 

that

 

you

 

can

 

start

 

data

 

plotting

 

(laser

 

head

 

will

 

move

 

from

 

left

 

to

 

right

 

side

 

during

 

the

 

plotting).

 

When

 

the

 

plotting

 

is

 

finished

 

and

 

the

 

switch

 

will

 

be

 

in

 

AUTO

 

position,

 

laser

 

head

 

will

 

move

 

back

 

to

 

its

 

starting

 

position

 

and

 

plotter

 

will

 

be

When

 

the

AUTO

 

mode

 

is

 

suitable

 

for

 

single

 

data

 

plotting

 

in

 

the

 

whole

 

film

 

width.

 

MANUAL

 

mode

 

is

 

suitable

 

when

 

you

 

want

 

to

 

plot

 

2

 

(or

 

more)

 

data

 ‐

side

 

by

 

side

 

(in

 

drum

 

axis

 

direction).

 

After

 

first

 

data

 

plotting

 

laser

 

head

 

moves

 

little

 

to

 

the

 

right

 

only

 

(1

 

cm)

 

and

 

next

 

plotting

 

starts

 

from

 

this

 

position.

  

 

If

 

you

 

turn

 

power

 

on

 

after

 

film

 

is

 

loaded,

 

it

 

may

 

happen

 

that

 

laser

 

light

 

beam

 

flashes

 

shortly

 

on

 

the

 

film

 

at

 

the

 

moment

 

when

 

power

 

is

 

turned

 

on

 

and

 

electronic

 

circuitry

 

is

 

reset.

 

This

 

may

 

result

 

in

 

very

 

small

 

spot

 

on

 

the

 

film.

Lift

 

the

lid,

 

so

 

you

 

have

 

access

 

to

 

the

 

outer

 

surface

 

of

 

the

(in

 

any

 

direction)

 

to

to

 

white

 

arrow

 

located

 

on

 

the

 

left

 

side

 

of

 

drum

 

holder.

 

This

 

is

 

the

 

outgoing

 

position

 

of

 

the

 

drum

 

for

 

photo

plotting.

 

The

 

left

 

top

 

corner

 

of

 

photo

plotted

 

area

 

is

 

then

 

approximately

 

20

 

mm

 

from

 

the

 

left

 

edge

 

of

 

the

 

drum

 

on

 

the

 

horizontal

 

line

 

marked

 

by

 

white

 

arrow.

 

Place

 

film

 

on

 

the

 

drum

 

with

 

its

 

top

 

edge

 

approximately

 

20

 

mm

 

behind

 

the

 

white

 

mark

 

on

 

the

 

drum,

 

hold

 

it

 

firm

 

by

 

hand

 

and

 

fix

 

it

 

to

 

the

 

drum

 

by

 

means

 

of

 

a

 

masking

 

tape

 

along

 

the

 

top

 

edge.

 

Rotate

 

drum

 

by

 

one

 

hand

 

to

 

be

 

able

 

to

 

fix

 

film‘s

 

bottom

 

edge,

 

but

 

make

 

sure

 

film

 

is

 

tight

 

on

 

drum

 

surface.

 

After

 

film

 

is

 

fixed

 

to

 

its

 

position

 

on

 

the

 

drum,

 

rotate

 

drum

 

back

 

to

 

1st

 

initial

 

position

 

(both

 

white

 

arrows

 

point

 

to

 

each

 

other).

 

Close

 

the

 

lid.

  

 

NOTES:

 

 

It

 

is

 

a

 

matter

 

of

 

practice

 

to

 

fix

 

film

 

properly

 

on

 

the

 

drum

 

surface.

  

 

Films

 

used

 

in

 

this

 

photoplotter

 

are

 

sensitive

 

to

 

light

 

of

 

670

 

nm

 

(red

 

light).

 

When

 

working

 

with

 

film

 

(loading,

 

unloading,…)

 

use

 

light

 

dark

 

green

 

light.

 

It

 

is

 

recommended

 

to

 

use

 

dim

 

light

 

in

 

room

 

during

 

photo

plotting.

 

Make

 

sure

 

there

 

are

 

no

 

other

 

sources

 

of

 

light

 

that

 

may

 

expose

 

film,

 

for

 

example

 

light

 

coming

 

from

 

monitor

 

screen,

 

when

 

loading

 

and

 

unloading

 

film.

 

The

 

film

 

manufacturer

 

can

 

recommend

 

proper

 

type

 

of

 

dark

 

room

 

safe

 

light

 

if

 

needed.

  

 

Transparent

 

films

 

must

 

be

 

mounted

 

with

 

emulsion

 

side

 

on

 

the

 

drum

 

surface.

 

(Film

 

in

 

rolls

 

used

 

for

 

image

 

setting

 

machines

 

has

 

emulsion

 

side

 

on

 

inner

 

side

 

and

 

therefore

 

it

 

is

 

easy

 

to

 

put

 

it

 

on

 

photoplotter

 

drum

 

properly).

 

Emulsion

 

side

 

of

 

the

 

film

 

has

 

light

 

grey

 

colour,

 

compare

 

with

 

dark

 

colour

 

of

 

the

 

other

 

side.

  

 

However,

 

films

 

made

 

for

 

laser

 

photo

plotters,

 

like

 

DuPont

 

films,

 

which

 

have

 

a

 

special

 

anti

reflection

 

coating

 

on

 

the

 

other

 

side

 

of

 

the

 

film,

 

cannot

 

be

 

plotted

 

with

 

emulsion

 

side

 

pointed

 

towards

 

drum

 

surface.

 

In

 

this

 

case

 

emulsion

 

side

 

must

 

be

 

on

 

outer

 

surface,

 

while

 

source

 

of

 

laser

 

light

 

may

 

need

 

to

 

be

 

re

focused.

 

From

 

this

 

reason,

 

use

 

transparent

 

films,

 

otherwise

 

laser

 

light

 

focus

 

must

 

be

 

adjusted
