Precautions

Before starting the disassembly or reassembly of the product, read the following precautions given under the headings "WARNING" and "CAUTION".

Warning / 警告
  • When the printer cover is opened, a safety-interlock mechanism causes the CR Motor and the PF Motor to stop. When the interlock function is disabled, be sure to take safety precautions and turn the function back to enabled after the operation.
  • This printer is equipped with a lithium battery. When handling the lithium battery, the following precautions should be followed.
    • When replacing the battery, replace it only with a specified type of battery. Using a different type of battery may cause excess heat or explosion. Specified battery: CR2032 (manufactured by Panasonic)

    • Dispose of used batteries according to manufacture’s instructions and local regulations. Contact your local government agency for information about battery disposal and recycling.

    • When disposing of the battery, be sure to securely cover its (+) end with tape to prevent combustion or explosion.

    • Do not recharge the battery.

    • Do not use the battery if it is discolored or damaged, or if any leakage of electrolyte is observed.

    • Do not dismantle, solder or heat the battery. Doing so could result in leakage of electrolyte, heat generation, or explosion.

    • Do not heat the battery or dispose of it in fire.

    • If the electrolyte leaked from the battery contacts with your skin or gets into your eyes, rinse it off with clean water and see a doctor immediately.

  • The power switch for this printer is installed on the secondary side of the power circuit; therefore, the power is always supplied unless the AC cable is unplugged. To prevent electric shock and circuit damage during servicing, make sure to follow the instructions below.

    • Before removing a circuit board, make sure to unplug the AC cable from the AC outlet and confirm the LEDs are turned off by pressing the Power button on the operating panel. This operation discharges the residual charge in the printer.

    • Make sure not to place the removed circuit boards on the metal and such directly.

  • Always wear gloves for disassembly and reassembly to avoid injury from sharp metal edges.

  • If ink gets in your eye, flush the eye with fresh water and see a doctor immediately.

  • If ink comes into contact with your skin, wash it off with soap and water immediately. If irritation occurs, contact a physician.

  • When replacing the Main Board, Power Supply Board, or power harnesses and such, make sure to check visually if any harness is caught in between or any wrong connection exists.

Caution / 注意
  • Locate the printer on stable and flat surface.
  • Use only recommended or s for disassembly, assembly or adjustment of the printer.
  • Apply lubricants and adhesives as specified.
  • Be careful not to soil the printer or the floor with the leaked ink when removing the ink-path-related components or parts. Spread a sheet of paper or cloth on the floor in advance.
  • Do not touch electrical circuit boards with bare hands as the elements on the board are so sensitive that they can be easily damaged by static electricity. If you have to handle the boards with bare hands, use static electricity discharge equipment such as anti-static wrist straps.
  • When the printer has to be operated with the covers removed, take extra care not to get your fingers or clothes caught in moving parts.
  • When you have to remove any parts or components that are provided as after-service-parts but are not described in this chapter, carefully observe how they are installed and make sure to remember it before removing them.
  • Disassembling the frame and some components (platen, PF shaft) of the printer is prohibited because they are assembled with precise measurements in 1/100 mm unit at the factory.
  • Never remove any screws because the platen of this printer is precisely adjusted in the manufacturing process.
  • Since the main board contains the customer’s personal information, when replacing the board, be sure to initialize or delete the save data after data transplantation and discard the failed main board.
