Check Installation of Print Head

If the print head is not installed correctly, the print results may not be as expected. To check the installation status, remove the print head once and reinstall it correctly using the following procedure.

  1. Press Setup button, use Left Right button to select Maintenance, and press OK button.

  2. Use Left Right button to select Start replacement and then press OK button.

  3. Open scanning unit / cover (top cover).

    Important

    • If the inside of the printer and the head are dirty with ink, clean with a soft cloth that gets wet with water and squeezed firmly before working. Also, be careful not to attach ink to clothes, etc. by the removed head.
    • Do not touch the metal part inside the printer and other parts.

  4. Close ink valve.

    Tilt the ink valve lever tightly to the left.

    The print head holder moves.

    Caution

    • Do not hold the print head holder by hand or move it forcibly while the print head holder is moving. Do not touch it until the print head holder stops moving.

    Important

    • If you leave the scanning unit / cover (top cover) open for more than 10 minutes, the print head holder may move and the Alarm lamp may light up. In that case, close the scanning unit / cover (top cover) once and open it again.

  5. Grab knob (A) on print head locking cover to open it.

  6. Pull the print head (B) and shift it slightly toward you.

  7. Remove left and right print heads.

    8. Important

    • When removing the print head, handle it carefully so that ink does not spatter.
    • Do not touch the ink tube or other parts inside the printer. Touching these parts may cause the printer to malfunction.

    • Do not touch the gold terminal (C) or print head nozzles (D) on a print head. The printer may not print properly if you touch them.

  8. Reinstall print heads properly.

    Install the print head labeled "L" in the left holder and the print head labeled "R" in the right holder.

  9. Close print head locking cover (E) and push it down.

    Press firmly the print head locking cover until it clicks into place.

  10. Press down both joint buttons (F).

    Important

    • Push the joint buttons firmly until they click into place; otherwise, printing may become impossible.
    • Make sure the left and right buttons are pushed in.

  11. Open ink valve.

    Tilt the ink valve lever tightly to the right.

  12. Close scanning unit / cover (top cover) gently.

    To close the scanning unit / cover (top cover), hold it up once, and then take it down gently.

  13. Print the nozzle check pattern.

    Print the nozzle check pattern to determine whether the ink ejects properly from the print head nozzles.

If the nozzle check pattern is not printed correctly even after checking installation of print head, problems may be solved by replacing the print head.
