Abstract
A spittoon for servicing an inkjet printhead is provided, where the spittoon includes a bottom and one or more walls. At least one wall of the spittoon has an inwardly extending lip. The walls of the spittoon, taken in combination with the bottom of the spittoon, define a waste ink reservoir. The presence of at least one lip on the spittoon walls helps retain the waste ink when the spittoon is moved or tilted, minimizing ink spills.
