摘要

Provided is printer assembly for a pagewidth printer, said assembly having a support frame for supporting a printhead arrangement. The support frame includes an outer wall portion and an inner wall portion separated by an internal cavity, as well as a lower arm portion and an upper wall fast with the outer and inner wall portions. The upper wall portion defines a channel for operatively receiving the printhead arrangement, said upper wall portion and arm portion having a clipping arrangement configured to complementarily receive a printed circuit board (PCB) support having electronic for controlling the printhead arrangement. The support frame is configured to minimize substantial dimensional changes due to environmental changes to retain a positional relationship between individual printhead tiles of the printhead arrangement.
