9.5. Nozzle Strong Maintenance
Perform this maintenance when the ejection failure is not improved even after performing
"STRONG" head cleaning multiple times (3 to 5 times).
Attach the head protection cover filled with cleaning solution to the print head and perform this
maintenance to improve nozzle clogging.
Clean white or color heads in a single operation.
When 30 minutes or more have passed after the carriage moves, the machine will cancel this
maintenance. As nozzle dryness may cause a nozzle defect, perform this maintenance
promptly.

The firmware version of printer that supports this maintenance is as follows.
・Panel (GIB) ：1.47
・Sub Control (SCB) ：1.13.231110
