[Important]

<Step 2>
Promptly perform head cleaning (Hard).
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 wiper rubber cleaning, cap rubber cleaning, and nozzle wash again.
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 execute [DISWAY WASH] and perform wiper 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.
