Abstract
An inker module for a high speed mailing machine is disclosed. The inker module includes a drive for moving an ink pad horizontally and vertically from a horizontal home position to a horizontal inking position in which the ink pad is tamped against a printing device which imprints postage indicia. The drive includes a single drive motor, cam wheels and links which cooperate to move the ink pad in the two directions. An ink pump is provided to pump ink to the ink pad each time that the ink pad is tamped against the printing device. The drive includes a further link to actuate the pump from the same motor. A platten device and its drive are disposed adjacent the ink pad drive to tamp an envelope or tape against the printing device in timed relation to movement of the ink pad.
