Redundant reorder prevention for replaceable printer components
First Claim
1. In a printing device having at least one replaceable component with component memory, a method comprising:
- ordering a new replaceable component to replace a current replaceable component in the printing device; and
storing a reorder value in the component memory to indicate that the new replaceable component has been ordered.

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.

3. The method recited in claim 1 further comprising:
-
sensing a trigger event indicative of a time to order the new replaceable component; and
wherein the ordering further comprises automatically ordering the new replaceable component.

8. A printing system comprising:
- a printing device;
a replaceable component installable in the printing device;
component memory incorporated into the replaceable component;
reorder data stored in the component memory that indicates whether or not a new replaceable component has been ordered to replace the replaceable component; and
an orderer configured to order the new replaceable component upon the occurrence of a trigger event if the reorder data indicates that the new replaceable component has not been ordered. - View Dependent Claims (9, 10, 11, 12, 13, 14)
a host computer connected to the printing device;
a component identifier stored in the component memory; and
wherein the orderer is further configured to retrieve the component identifier and store the component identifier in memory of the host computer.
- a printing device;
-
14. The printing system recited in claim 8 further comprising:
-
a host computer connected to the printing device;
a vendor system from which the new replaceable component is ordered, the vendor system being configured to communicate with the host computer;
a component identifier stored in the component memory; and
wherein the orderer is further configured to retrieve the component identifier and store the component identifier in memory of the vendor system.

15. A printer comprising:
-
a replaceable component having component memory incorporated therewith; and
a reorder indicator stored in the component memory, the reorder indicator having a first state to indicate that a new replaceable component has not been ordered, and a second state to indicate that a new replaceable component has been ordered. - View Dependent Claims (16, 17)
a status monitor configured to poll the reorder indicator before the orderer orders the new replaceable component;
the orderer being configured to order the new replaceable component upon the occurrence of a trigger event if the status monitor indicates that the reorder indicator is in the first state.
