A

new

heat

-fixing

unit

will

be

provided

with

the

heater

thermistor

harness

being

taped

to

the

unit.

Before

installing

the

unit,

remove

the

tape.

•

If

you

remove

and

reinstall

the

heat

-fixing

unit

because

of

any

failure,

make

the

equipment

enter

the

maintenance

mode

(by

pressing

the

Menu,

*

2,

8,

6,

and

4

keys)

after

completion

of

reassembly

and

then

make

it

exit

from

the

mode

(by

pressing

the

9

key

twice).

Otherwise,

the

heat

-fixing

unit

may

not

become

energized

because

of

the

following

reason:

If

the

failure

of

the

heat

-fixing

unit

is

caused

by

an

opening

of

the

thermistor

circuit

(that

senses

the

temperature

of

the

heat

-fixing

unit),

the

system

misinterprets

the

hot

heater

as

being

cold.

As

a

result,

the

temperature

of

the

heat

-fixing

unit

may

become

excessively

high.

To

prevent

the

system

from

heating

the

hot

heater

further

at

the

next

powering

-on,

it

is

designed

so

that

the

heater

will

not

be

energized.

To

cancel

this

setting,

you

need

to

carry

out

the

above

maintenance

-mode

procedure.
