Aspects of a method and system for minimizing effects of transmitter impairments in multiple input multiple output beamforming communication systems are presented. A first reading receiver receives a first reading instruction to cause the document reading unit to continue reading a plurality of documents in the first reading mode when a jam is detected. The tamper detector has output and input elements for connection to ends of a tamper detection circuit, wherein the detection circuit is linked with a physical closure surrounding an electronic circuit. In some circumstances, the event may be a delay in delivery of the mailpiece due to contamination or quarantining, and the sender’s instructions may specify a manner in which the contents of the mailpiece may be forwarded to the addressee while the mailpiece remains quarantined. The timer and temperature control systems are programmed by data transmitted from the hand held computer.
