Abstract

A postage meter having a rotable print drum also has a control arrangement ensuring that power is fed to the motor which drives the print drum via at least two parallel paths. One of these paths is operative to cause the motor to be driven until an envelope trip switch signifies that the envelope is fully discharged from the meter, irrespective of whether the other path is electrically conductive or not.
