Abstract
Abstract A fuser module, being a fuser subsystem installable in a xerographic printing apparatus, includes an electronically-readable memory permanently associated therewith. The control system of the printing apparatus reads out codes from the electronically-readable memory at install to obtain parameters for operating the module, such as maximum web use, voltage and temperature requirements, and thermistor calibration parameters.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
109 words
A module installable in a printing apparatus, comprising: a heat element; an electronically-readable memory; a first code and a second code retained in the electronically-readable memory, the first code being symbolic of a operating requirement of the heat element for fusing marking material on a print sheet passing relative to the heat element when the module is installed in an apparatus which operates at a first speed, and said second code being symbolic of a operating requirement of the heat element for fusing marking material on a print sheet passing relative to the heat element when the module is installed in an apparatus which operates at a second speed.
Claim 2
Dependent Claim
109 words
A module installable in a printing apparatus, comprising: a heat element; an electronically-readable memory; a first code and a second code retained in the electronically-readable memory, the first code being symbolic of a operating requirement of the heat element for fusing marking material on a print sheet passing relative to the heat element when the module is installed in an apparatus which operates at a first speed, and said second code being symbolic of a operating requirement of the heat element for fusing marking material on a print sheet passing relative to the heat element when the module is installed in an apparatus which operates at a second speed.
