NeuraLabel Callisto User Manual page 50

If narrow labels are printed for an extended period of time, followed by wider labels, the dies
that have not been used may appear to produce slightly different color ink because of dried bits
of ink in the tubes and nozzles. Likewise if only certain ink colors are used, there is a similar
risk. Turning Background Spitting on can help prevent this problem.
Activating Background Spitting may result in slower printer speeds because the entire width of
the printhead is used. There may be tiny specs of ink on the printed image that in some cases
are visible to the naked eye. NeuraLabel's previous generation inkjet printer used the
Background Spitting feature. While the Callisto printer offers the feature as an option, end
users should consider enabling background spitting by default or if print quality issues as
described above emerge.
The Callisto printer does include periodic service routines to exercise all printer dies and colors.
As-needed printhead cleanings are also useful for keeping the printhead in a healthy state.
