Abstract
An imaging apparatus includes a printhead carrier configured for movement along an X-axis. The printhead carrier includes a carrier housing having a first bearing pocket and a second bearing pocket. The first bearing pocket and the second bearing pocket are spaced apart along the X-axis. A Z-axis passes through a central region of the carrier housing. The Z-axis is substantially perpendicular to the X-axis. A first bearing is configured to be received in the first bearing pocket. The first bearing includes a first curved outer surface having a curve that extends in a direction of the X-axis. The curved outer surface is received in the first bearing pocket to facilitate a rotation of the first bearing in relation to the Z-axis of the carrier housing. A second bearing is configured to be received in the second bearing pocket.
