Abstract
A redundant reorder prevention system prevents redundant reorders for replaceable components in printing devices. The replaceable component has memory integrated therein which contains a reorder value field. The reorder value field is initially configured in a first state which indicates that a new replaceable component has not been ordered to replace the current replaceable component. Before the system orders a new replaceable component, it checks the reorder value field. If the first state is detected, a new replaceable component is ordered and the reorder value field is reconfigured to a second state which indicates that the new replaceable component has been ordered. If the second state is detected before an order is placed, the order process is terminated before a new replaceable component is ordered.
