The UP-X898MD mounts a lithium battery for operating a watch. The lithium battery is parts that have
the length of life. It is recommended to replace it when five years pass after a lithium battery is manufac­tured.

. Be sure to use IEC-60086-4 certified products as a lithium battery.
. Use a lithium battery (CR2032 type): 1-528-174-72 during replacement.

Replacement

1. Remove the top cover. (Refer to Section 1-5-1.)

2. Remove the lithium battery from the battery holder on an MA-195 board.

1-11. Cleaning

1-11-1. Cleaning the Cabinet

n

When solvents such as benzene or thinner, or acid, alkaline or abrasive detergent, or chemical cleaning
cloths are used on the dirty cabinet, the surface finish may be damaged. Take care with respect to the
following:
. Clean the cabinet with a 50 to 70 v/v% concentration of isopropyl alcohol or a 76.9 to 81.4 v/v% con-

centration of ethanol.

. Stubborn stains may be removed with a soft cloth such as a cleaning cloth lightly dampened with mild

detergent solution and then clean using the above chemical solution.

. Do not use unnecessary force to rub the cabinet with a stained cloth. The cabinet may be scratched.
. Do not keep the cabinet in contact with a rubber or vinyl resin product for a long period of time.

The surface finish may deteriorate or the coating may come off.

1-11-2. Cleaning the thermal head

If the thermal head is contaminated, the streaks, white spots or scratches may appear on the print image.
Wipe the stains of the thermal head with a clean and soft cloth dampened with ethanol in concentrations
of 76.9 to 81.4 v/v%.

n

Do not use the gauze because it generates debris.

1-11-3. Cleaning the Platen Roller

If the paper cannot be fed smoothly when printing or if the paper can be easily pulled out by hand, the
platen roller may be dirty. In such a case, clean the platen roller with a soft cloth soaked in a 76.9 to 81.4
v/v% concentration of ethanol.

1. Turn on the power switch.

2. Press the [OPEN] button to open the door panel assembly.

3. Wipe the platen roller gently with a soft cloth soaked in ethanol.
n
. After the wiped surface is completely dried, press the [FEED] button to rotate the platen roller and

wipe other portion.

. Do not rotate the platen roller with the hand.
. Do not use the gauze because it generates debris.

4. Press the [FEED] button.
The platen roller rotates by about 120 degrees.
n
After the platen roller stops, start cleaning the platen roller.

1-14. Lead-free Solder

All boards mounted in this unit use lead-free solder. Be sure to use lead-free solder when repairing the
boards of this unit. A lead free mark (LF) indicating that the solder contains no lead is printed on each
board.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular
size.)

: LEAD FREE MARK

n
. The lead-free solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is

recommended to use the soldering iron having a temperature regulator.

. The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly

longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so
be careful.

When replacing the thermal head, be sure to perform the following procedure.

Start

Perform “3-7-2. Sample (Gray)
Printing”.

Are there any streaks (white or
black) and scratches in the
paper feed direction?

Yes

Perform the cleaning of thermal
head. (Refer to Section 1-11-2.)

Perform “3-7-2. Sample (Gray)
Printing”.

Did the streaks and scratches
disappear?

Yes No

End

No

No

End

Yes

Improved?

Replace the thermal head.
(Refer to Section 3-7-3.)

Perform the check.
(Refer to Section 3-13.)

$

When replacing with the new thermal head, write down the
head resistance value (.e.g. R13152) and serial number
(e.g.3C-00121) indicated on the attached label before attaching it.

&

The resistance value of the heater portion varies depending
on the thermal head.
Even though the head voltage is the same, the energy to be
applied varies individually.
When replacing the thermal head, perform the voltage
adjustment of thermal head because the density of print before
and after replacement should be the same.
