ABSTRACT:
A technique for triggering refill of a take-a-gulp ink delivery system during printing of a plot. The system includes the capability of tracking the ink volume remaining in one or more of the on-board ink reservoirs, and detecting when a reservoir needs refilling. If this occurs while plotting, the system can invoke a refill operation as if doing a normal pen servicing, which entails moving the carriage to the service/refill station, even though the plot is not completed, and performing a refill operation. To minimize artifacts of the plot due to the printing interruption, a location to interrupt the plot at which the ink density is low is selected based on the prior history of the plot.
