ABSTRACT:
The electronic postage meter includes a microcomputer controlled thermal head opposite a scavenging roller and suitable means of cleaning the scavenging roller. A cassette containing a thermal transfer tape coated on one side with a thermal sensitive ink is received within a cartridge slot in the postage meter. The thermal tape is threaded within the cartridge to journal from a feed reel beyond a guide roller, between a thermal head and scavenging roller, to a transfer roller and be received by a take-up reel, the scavenging roller and thermal head being constituent of the postage meter. The mailing machine includes a back-up roller bias peripherally opposite the transfer roller. An image is traced on the thermal tape by the thermal head in response to a microcomputer constituent to the postage meter. The thermal tape is driven therefrom to the transfer roller which is maintained at a temperature substantially above the ink transfer temperature of the thermal tape to be imparted on a traversing mailpiece along a mailing machine deck.
