Abstract
In an inkjet printing apparatus an inkjet printhead ejects ink into a print-zone. A drive shaft, located upstream of the printhead, has a longitudinal axis, a first radius over a central length, and a second radius less than the first radius at a first recess and a second recess. Each recess is peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide and a second guide, spaced from the longitudinal axis, are aligned with and extend into the first recess and second recess.
