- Selector 3: Black ink print mode
If any color ink runs out, printing is no longer possible by default. Setting this selector
to "1" allows the machine to function as a monochrome printer, making it possible to
print with black ink only even in a "Replace Ink" state as listed below.

Tip: Difference between selector 3 on AMS04 and selector 8 on WSW49 (For
details, refer to the "Worker Switches (WSW)" document separately issued.)
Both selector 3 on AMS04 and selector 8 on WSW49 specify the similar black
ink print mode that applies if any color ink runs out. The difference is that the
former allows the machine to print all data received as a monochrome printer
with black ink only; the latter to ignore the "Replace Ink" state, receive both
color and black data, and print it, resulting in a printout missing color
components.
- Selectors 4 and 8: Automatic purging for color ink and for black ink
The machine periodically performs an automatic purge by default. The automatic
purge, however, wastes ink when no printing has occurred. To avoid it, disable the
automatic purge with these selectors. In the first printing after a long no-print period,
disabling it may lower the print quality.
Setting selector 4 or 8 to "1" disables the setting made by selectors 6 and 7.
