UP-800F/810F (V) LEAD-FREE SOLDER
■ LEAD-FREE SOLDER
The PWB’ s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder. The
alphabet following the LF mark shows the kind of lead-free solder.
Example:
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is
recommendable.
recommendable.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity is inferior to
conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may exceed the heat-resistive tem-
perature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is confirmed.
perature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after com-
pletion of soldering work.
pletion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean
and file the tip with steel wool or a fine filer.
and file the tip with steel wool or a fine filer.
■ SPECIAL CAUTIONS
Target model : UP-800F/UP-810F
Special cautions for production and servicing are described below.
Special cautions for production and servicing are described below.
(1) TOUCH PANEL
• Since transparency is the vital factor of the transparent touch panel, use a great care not to put fingerprints or dirt on the transparent touch panel.
Use clean finger sucks, gloves, and a mask, and never touch the visible area.
• Do not apply a pressure to the pressure-inhibit area of the touch panel when assembling and handling.
• Since the glass edges are not chamfered and there are some sharp edges, always use finger sucks or gloves when handling.
[Inhibition]
• Never hold the flexible pattern section of the transparent touch panel in order to maintain the reliability.
• Never put a touch panel over another in order to prevent them from scratching.
• Never put a heavy material, a hard material, or a sharp material on the transparent touch panel.
• To remove dirt from the surface of the transparent touch panel, use soft cloth immersed in ethyl alcohol. If, however, ethyl alcohol soaks into the
attachment section of the film and the glass, separation or malfunction may occur. Use enough care for it.
(2) PRINTER MECHANISM
• If there is a scratch or dirt on the platen roller or the platen drive wheel, defective printing may occur. If an external pressure is applied to the plate
section, it may be deformed easily. Use enough care when assembling and handling.

UP-800F/810F (V) PRECAUTION
• If an external pressure is applied to the lever, it may be deformed. Use enough care when assembling and handling.
• When fingers come close to the thermal head in installation or removal of the printer or in paper replacement, static electricity may damage the
heating element and the IC’s. To prevent against this, be sure to use charging protection as well as human body earth before handling. Use
extreme care for the heating element on the thermal head surface and the thermal head control terminal.
• Be careful not to apply an extra force to the thermal head control terminal, or the connector may be damaged.
• When connecting or disconnecting the connector, be sure to turn OFF the power and disconnect the AC plug from the power outlet.
(3) LCD UNIT AND INVERTER UNIT
• When connecting or disconnecting the cable, be sure to turn OFF the power and disconnect the AC plug from the power outlet in order to prevent
the circuit parts from breakage. At that time, hold the connector on the PWB side and connect or disconnect the cable in order not to apply an
excessive stress to the PWB.
• When assembling a unit, use enough care not to warp or twist it.
• When handling, be sure to use human body earth to remove static electricity. Of course, the normal handling cares for electronic parts must be
observed. (Static electricity, shock, heat, moisture, etc.)
• When removing the scratch protection film (laminate film) of the LCD panel surface, static electricity may be generated. When removing, therefore,
discharge static electricity (by discharge blow) and remove slowly.
• Since the LCD panel surface (deflecting plate) is easily starched, use great care not to touch it with a hard or sharp material.
• If a water drop remains on the LCD panel, it may cause discoloration or stain. Clean and remove it at once.
• When the LCD panel surface is stained, clean with soft cloth or absorbent cotton.
• Since the LCD backlight section and the inverter unit are applied with a high voltage, they may cause an electric shock. When repairing or replacing
the lamp, be sure to turn OFF the power before executing the work.
• When cleaning the panel surface, grip a Dusper with clips, soak it in ligroin solution, and wipe and clean the panel vertically and horizontally. Do not
apply an excessive force, and do not move the Dusper in a circle or do not scrub.
(4) KEYBOARD
• Since transparency and maneuverability are important factors for the key sheet rubber, use finger sucks or gloves when handling. Do not use a
hard or sharp material to operate it.
• If water or oil is attached to the key sheet rubber, it may cause discoloration or stain. Clean and remove it at once.
(5) GND WIRE, FERRITE CORE
• Be sure to use only the GND wire and the ferrite core which are specified on the Parts Guide.
• If a hard shock is applied to the ferrite core, it may be damaged or broken. Use enough care to handle it.
PRECAUTION
BATTERY DISPOSAL
Contains a Nickel Metal Hydride Battery pack. Must be Disposed of
Property. Contact Local Environmental Officials for Disposal Instructions.
