Automatically Detecting and Registering Nozzle Clogging
When nozzle checking is executed on the machine, the NCU, which monitors the print head nozzle status,
automatically detects and registers the location where a nozzle is clogged.
There are two types of nozzle checking: "Nozzle check" performed as required by the user, and "Nozzle
check before print" performed automatically before starting printing.
l
Nozzle check
This performs nozzle checking to manually detect and register those nozzles that are clogged.

locations are automatically registered. To close the window, tap [×] at the top right of the window.

Nozzle check before print
When printing, nozzle checking is automatically performed before printing starts. When this function is
enabled, nozzle checking is performed automatically before printing starts, so printing is stopped for
approximately four minutes to allow nozzle checking to be performed.
