Abstract
A printer includes: a first fixed printhead; a second fixed printhead positioned downstream of the first printhead relative to a media feed direction; a fixed platen for supporting print media; an input roller assembly positioned upstream of the first printhead, the input roller assembly comprising a pair of input rollers having a first nip force N1; an output roller assembly positioned downstream of the second printhead, the output roller assembly comprising a pair of output rollers having a second nip force N2; and an intermediary roller assembly positioned between the first and second printheads, the intermediary roller assembly comprising a pair of intermediary rollers having a third nip force N3. The nip forces satisfy the relationship N1>N2>N3 for optimal printing results.
