Head

consists

of

a

laser

diode

that

is

very

susceptible

to

external

static

electrocity.

Although

it

operates

properly

after

replacement,

if

it

was

subject

to

electrostatic

discharge

during

replacement,

its

life

might

be

shortened.

When

replacing,

use

a

conductive

mat,

soldering

iron

with

ground

wire,etc.

to

protect

the

laser

form

damage

by
