• 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. 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 ambient
temperature
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.
