(all

If

smaller,

 

decrease

 

diameter

 

value,

 

if

 

dimension

 

is

 

bigger,

 

increase

 

drum

 

diameter.

 

To

 

estimate

 

correct

 

drum

 

diameter

 

use

 

the

 

following

 

formula:

 

multiply

 

current

 

drum

 

diameter

 

with

 

ratio

 

of

 

measured

 

distance

 

on

 

300mm

 

and

 

300

 

(or

 

any

 

other

 

distance).

 

For

 

example,

 

measured

 

distance

 

in

 

drum

 

circumference

 

on

 

300

 

mm

 

grid

 

is

 

300.1,

 

while

 

current

 

drum

 

diameter

 

is

 

157.45.

 

New

 

drum

 

diameter

 

will

 

be

 

300.1/300

 

multiplied

 

by

 

157.45

 

=

 

157.50

 

Please

 

note

 

that

 

this

 

drum

 

diameter

 

is

 

not

 

real

 

drum

 

diameter,

 

but

 

little

Maintenance

 

 

There

 

are

Keep

 

drum

 

clean

 

and

 

protect

 

inner

 

space

 

of

 

the

 

plotter

 

from

 

falling

 

objects.

 

Keep

 

the

 

lid

 

closed

 

at

 

all

 

times

 

except

 

loading

 

and

 

unloading

 

film.

 

Use

 

basic

 

cleaning

 

chemicals

 

and

 

soft

 

cloth

 

to

 

clean

 

drum

 

surface

 

from

 

sticky

 

areas

 

left

Note

:

 

If

 

you

 

need

 

to

 

open

 

the

 

plotter,

 

remove

 

all

 

screws

 

and

 

carefully

 

lift

 

the

 

upper

 

part

 

of

 

the

Note

:

 

Do

 

not

 

rotate
