Document characteristics such as print media and selectable print quality variations are used to determine printhead servicing, e.g., service spitting of ink-jet nozzles. If the next sweep contains the next color in the pen or printhead set, and the next sweep would be greater than the number of sweeps since the last firing of that color ink&mdash;whether on page or at the service station&mdash;and the last sweep did not fire droplets of the color, a decap service spit and nozzle firing tracking reset is triggered. All service calls spit fire all nozzles, so all timer values are reset whenever at a service spit. Reaching or exceeding a fail-safe limit similarly triggers a decap service spit or other known manner service station operations.
