Abstract

A method and apparatus for monitoring the quality and performance of a product that utilizes end user serviceable components and consumables. In illustrative embodiments, a calibration procedure is employed to determine when and if sub-standard third party replacement components are employed. If such a component is detected, a notification is made to the end user or a service provider. Under certain conditions, the product can be disabled. In another embodiment, electronic labels are employed within the replaceable components. The electronic labels are used to determine the source and quality of the replaceable components, and to interface to sensors which can monitor the consumption of consumables, or for other purposes. Warranty and service costs can be established based on the utilization of the present teachings.

Claims

1. A method for monitoring the performance of an apparatus comprising the steps of:

performing initial calibration procedure to produce a first performance metric;

detecting the presence of a third party user serviceable component by identifying the absence of a predetermined electronic label;

performing a subsequent calibration procedure to produce a second performance metric;

comparing said second performance metric with said first performance metric, and

outputting a performance factor indicative of a change in performance resulting from the use of said third party user serviceable component.

2. A method of identifying the presence of third party replacement consumables in an apparatus the method comprising the steps of:

reading first information indicative to an amount of consumption of a consumable from an electronic label for an originally installed user serviceable component;

storing said first information;

subsequently repeating said reading step to produce second information indicative of an amount for consumption, and

comparing said second information with said first information thereby identifying an increase in the amount of the consumable;

outputting a replacement indicator indicative of an increase in the quantity of said consumable.

3. A method of identifying invalid service claims for an apparatus having user serviceable components, comprising the steps of:

performing initial calibration procedure to produce a first performance metric;

performing a subsequent calibration procedure to produce a second performance metric;

comparing said second performance metric with said first performance metric;

outputting a performance factor indicative of a reduction in performance resulting from a change in the user serviceable components with a third party user serviceable component, and

determining the validity of a subsequent service claim according to said performance factor.

4. The method of claim 3 further comprising the step of establishing the cost of providing service for the apparatus according to said determined validity of the service claim.

5. A method of identifying invalid service claims for an apparatus, wherein certain originally installed user serviceable components include an electronic label, the method comprising the steps of:

performing initial calibration procedure to produce a first performance metric;

detecting the presence of a third party user serviceable component by identifying the absence of a proper electronic label;

performing a subsequent calibration procedure to produce a second performance metric;

comparing said second performance metric with said first performance metric;

outputting a performance factor indicative of a change in performance resulting from the use of said third party user serviceable component; and

determining the validity of a subsequent service claim according to said performance factor.

6. The method of claim 5 further comprising the step of establishing the cost of providing service for the apparatus according to said determined validity of the service claim.

7. An apparatus having user serviceable components, the apparatus being operable to monitor its own performance and comprising:

means for performing initial calibration procedure to produce a first performance metric;

means for detecting the presence of a third party user serviceable component by identifying the absence of a predetermined electronic label;

means for performing a subsequent calibration procedure to produce a second performance metric;

means for comparing said second performance metric with said first performance metric; and

means for outputting a performance factor indicative of a change in performance resulting from the use of said third party user serviceable component.

8. An apparatus having user serviceable components, certain of which have electronic labels, and having consumables in the user serviceable components, the apparatus, comprising:

means for reading first information indicative of an amount of consumption of a consumable from an electronic label for at least one originally installed user serviceable components;

a memory for storing said first information;

means for subsequently reading second information indicative of an amount for consumption of said consumable from said electronic label;

means for comparing said second information with said first information thereby identifying an increase in the amount of the consumable; and

means for outputting a replacement factor indicative of an increase in the quantity of said consumable.
