Even after maintenance, issues such as nozzle dropout and deflection remain unresolved.

  • If foreign objects on the nozzle surface are the cause, powerful maintenance with Maintenance Liquid 16 may resolve firing issues.


When performing powerful maintenance using Maintenance Liquid 16 for the first time, please consult our engineers for the procedure in advance.

*The powerful maintenance may not resolve all firing issues.
Firing issues caused by factors other than foreign objects on the nozzle surface may not be resolve


Please be sure to confirm in advance.

How to perform powerful maintenance
<Step 1>

Select [Head Maintenance] and clean the nozzle surface using Maintenance Liquid 16.
(1) On the LOCAL mode screen, select [MENU] > [MAINTENANCE], then press the [ENTER] key.
    the [ENTER] key.
   The carriage moves to the maintenance area.
(3) Fold the included maintenance cloth in half and drop Maintenance Liquid 16 onto the folded part,
   allowing it to soak in.
- Amount to drop: 6ml (approx. 3 doses with the included syringe).
Please make sure to use the cloth provided in the kit.
- Do not reuse a maintenance cloth once it has been used; always use a new maintenance cloth.

(4) Open the maintenance cover and allow Maintenance Liquid 16 to penetrate the nozzle

     surface of the head where firing issues have occurred.

  - Press the maintenance cloth soaked with Maintenance Liquid 16 against the entire nozzle

    surface of the head for 2 to 5 minutes.

  - Do not rub the nozzle surface or press it forcefully with your fingers.

    Scratching the nozzle surface can cause firing issues.



(5) Close the maintenance cover and press the [ENTER] key.
After completion, please proceed immediately to the next step 2 without delay.

<Step 2>

Please refer to the "Operation Manual" for the head cleaning procedures.

<Step 3>
Perform a test print to confirm if the firing issue has been resolved and if there are any abnormalities
in the color of the print result.
■ If the firing issue does not recover:
   Return to Step 1 and perform nozzle surface cleaning again with a new maintenance cloth.
   If there is no improvement even after performing it three times, please contact our call center.

■ If firing issues have been resolved but there is an issue with color
    (such as being too light or mixed colors):

   Please perform cleaning and wiper nozzle cleaning using the
   maintenance liquid for daily maintenance (not suitable for Maintenance Liquid 16).
   If no improvement is observed, please contact our call center.

■ If recovery is successful and there are no color issues:
   Powerful maintenance is complete.
