1. A print engine comprising:
- a media support chassis having a plurality of guide rollers mounted between opposite sidewalls thereof, the plurality of guide rollers defining a curved media feed path;
a plurality of spittoons, each spittoon being positioned between a neighboring pair of guide rollers and each spittoon having an upper guide portion; and
a plurality of printheads, each printhead opposing a respective spittoon,wherein;
the upper guide portion at least partially intersects a common tangential plane defined between a neighboring pair of rollers, such that print media fed along the curved media path contact the rollers and upper guide portions of the spittoons; and
the upper guide portion of each spittoon comprises an upstream leading edge sloped towards the media feed path and a downstream trailing edge sloped away from the media feed path.
