ABSTRACT:
In a serial impact printer including a platen for supporting an image receptor, the platen having a central shaft and a cylindrical impact absorbing sleeve secured thereto, a platen mounting arrangement is provided which is capable of withstanding rapidly repeating, long duration, high impact loads without generating extraneous noise. The ends of the shaft are captured in seats capable of withstanding, without distortion, a high impact printing force in the impacting direction, and are retained in the seats by spring biased arms which restrain the ends of said shaft from rebound movement in a second direction substantially opposite to the impacting direction.
