Abstract

This concept proposes a process that makes efficient use of the CRUM (Customer Replaceable Unit Monitor) technology during manufacturing, field operation and re-manufacturing with the objective of enhancing productivity, product quality, and ultimately customer satisfaction. This process is supported by an infrastructure that consists of a number of software and hardware tools that facilitate data collection, standardized analysis and sharing of the information across the critical groups involved, marketing, field engineering, continuing engineering, production and recycling centers.

Customer Replaceable Unit Monitor Data Collection and Utilization Process

In the past, Customer Replaceable Unit (CRU) field problems and production issues have been dealt with by collecting a small sample set of CRU and CRUM’s (Customer Replaceable Unit Monitors) and performing detailed analysis. The results have then been generalized to the CRU population resulting in proposals for design changes and new procedures. Because the sample set is small and there are no standardized tools for the collection, sharing and analysis of the data as well as the suggested course of action have been open for interpretation. It is also difficult to verify if the improvements had any impact on the original problem.

This concept proposes a process that makes efficient use of the CRUM technology during manufacturing, field operation and re-manufacturing with the objective of enhancing productivity, product quality, and ultimately customer satisfaction. This process is supported by an infrastructure that consists of a number of software and hardware tools that facilitate data collection, standardized analysis and sharing of the information across the critical groups involved, marketing, field engineering, continuing engineering, production and recycling centers.

CRUM Introduction and Premises:

The CRUM is essentially an electronic file cabinet that holds information stored by the machine Image Output Terminal (IOT). The information type and contents varies from product to product. In general the information can be classified in the following types:

·        Customer Information: Enables features that allow the machine to provide dynamic feedback to the customer in terms of the CRU life, error conditions, reorder points, yield information, etc. during machine operation.

·        Manufacturing information: This is information such as date of manufacture, product type, CRU serial number and others. This data enables traceability of the supplies made at any one of our production facilities, it facilitates problem analysis and provides a signature that can also be used to identify units in the unwanted event of re-calls.

·        Machine control/behavior information: This data is used to control the xerographic engine behavior. This type of data enables the IOT to perform functions such as adjustments to the xerographic engine to maintain performance quality through out the life of the CRU.

·        Marketing Information: This information permits the implementation of marketing features such as geographic and price plan differentiation among others.

By collecting and analyzing this data, it is possible to better understand in a short time frame the usage of machines, weaknesses, problem areas, etc. and issue corrective action. However in order to maximize the gains of the CRUM technology it is important that a minimum set of information be stored in the CRUM. The table below shows that minimal set of data as well as a suggestion for additional types of information.
