Head and cap transport parts cannot come off

When transporting the main unit, it is necessary to attach the transportation parts for the head and the cap. If forget to remove this part when unpacking or after transportation and turn on the power, the head unit and cap unit will interfere with this part and become locked, causing a fatal error.
Fatal error can be resolved by removing the transport parts, but depending on the mechanical state, it may not be possible to remove the transport part. In this case, it is necessary to change the positions of the head unit and the cap unit by following the procedure below.

Note / 補足
  • The fatal error that occurs is as follows.
    • If you forget to remove the head transportation part: Related to HEAD PID error (000840/000841/000842/000843/000844)
    • If you forget to remove the cap transportation part: Related to CAP PID error (000500/000501/000502/000503/000504)


When checking the device status

  1. Turn off the power and check if the transportation part for the head and cap can be removed or not.

    Note / 補足
    • Head Transportation Part
      Open the front cover, hold the handle of the transport parts, and pull it forward while rocking it left and right.
    • Head Shaft Transportation Parts
      Set the paper in advance to prevent ink stains, inserting your hand inside the curve of the transportation part at the ink  cartridge insertion part, rotate it upward and pull it out.

    • Cap Transportation Part
      Open the right door unit and belt unit, and push the handle of the transport parts to the rear.

  2. Change the position of the head unit or cap unit according to the transport part that could not be removed.
