Overview

This section provides information on how to maintain the printer in its optimum operating condition.
Basically, servicing on the printer should be performed on-site. Be sure to strictly observe the following precautions when servicing to avoid an accident or injury causing the user trouble.

Warning / 警告
  • The power switch is installed on the secondary side of the power circuit, so power is always supplied to the power supply circuit even when the switch is OFF unless the power cord is unplugged from the wall power outlet. Unless otherwise stated (for printing or operation checks), be sure to unplug the power cord from the wall outlet before disassembling or assembling the printer to prevent electric shock and damage to the circuit.
  • The Front Sensor provided for detecting open/close status of the Printer Cover also acts as a safety interlock switch. Never disable the switch function to prevent possible injury.
  • A lithium battery is mounted on the Main Board (control circuit) for memory backup. Be sure to observe the following precautions when handling the Main Board.
    • Be careful not to short the electrode of the battery.

    • When replacing the battery, make sure to insert it in correct orientation.

    • Never heat the battery or plunge it into the flames.

    • Do not put the Main Board directly on conductive materials

  • Be extremely careful not to get the ink into your eye or let it come into contact with your skin. If it happens, wash out your eye or skin with water immediately. If any abnormality is found, contact a physician.
Caution / 注意
  • Ensure sufficient work space for servicing.
  • Locate the printer on a stable and flat surface.
  • WHEN AIR DUSTER IS USED ON THE REPAIR AND THE MAINTENANCE WORK, THE USE OF THE AIR DUSTER PRODUCTS CONTAINING THE INFLAMMABLE GAS IS PROHIBITED.
  • Be sure to spread a sheet of paper or cloth on the work space before removing any ink-path-related parts or components to keep the space from being soiled with leaked ink.
  • 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 such as the fan unit.
  • When the printer needs to be repacked for transportation after being used, make sure to follow the steps below after turning the power OFF.
    • Check that the Printhead is capped properly.
    • Leave the ink cartridges installed in the printer.
    • Repack the printer using the packaging box, cushioning materials and protective equipment indicated in the unpacking guide.
