Selector 1: Protection of head caps from drying

If the protection function is enabled with this selector, the head/carriage unit automatically
returns to the home position (head capping position) for flushing each time the machine prints
the specified number of pages in order to protect the inside of the head caps from drying up.
This function is useful in a dry environment or for heavy duty print per printing cycle.
Selectors 2 and 3: Auto capping start time

If data transfer from the PC stops midway through printing for some reason in the PC, the head/
carriage unit automatically returns to the home position (head capping position) after the
specified auto capping start time (default: 30 seconds) to prevent the head surface from drying
up. At the restart of printing after the auto capping operation, print image unevenness could
occur. At the restart of printing after the auto capping operation, print image unevenness could
occur. To avoid it, increase the auto capping start time with these selectors.
Selector 4: Purge more powerful than normal purge

Setting this selector to "1" automatically selects a purge more powerful than the normal purge
from the first if the purge is initiated immediately after printing.
Selectors 7 and 8: Automatic purging interval programmed for matching the

The "automatic purging interval programmed for matching the ambient temperature" is enabled
by default. If the machine is set in an excessively hot or cold place, therefore, the automatic
purging interval becomes short, resulting in increased ink waste.
Disabling this interval enables the one programmed for the ordinary temperature. In the first
printing after a long no-print period, however, the print quality may lower.
