Claims
- 1. 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.
- 2. The module of claim 1, the operating requirement being a predetermined voltage.
- 3. The module of claim 1, the operating requirement being a predetermined power.
- 4. The module of claim 1, the operating requirement being a predetermined temperature.
- 5. The module of claim 1, the operating requirement being a predetermined maximum or minimum temperature.
- 6. A method of operating a printing apparatus, comprising the steps of:
- providing a module separable from the digital printing apparatus, the module comprising a heat element and an electronically-readable memory;
- the digital printing apparatus reading one of a first code symbolic of an 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 a second code symbolic of an 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.
- 7. The method of claim 6, the operating requirement being a predetermined voltage.
- 8. The method of claim 6, the operating requirement being a predetermined power.
- 9. The method of claim 6, the operating requirement being a predetermined temperature.
- 10. The method of claim 6, the operating requirement being a predetermined maximum or minimum temperature.
- 11. A module installable in a printing apparatus, comprising:
- a web suitable for treating a fuser roll, the web being movable relative to the fuser roll;
- an electronically-readable memory;
- at least a first code retained in the electronically-readable memory, said code being symbolic of a maximum use of the web.
- 12. The module of claim 11, further comprising a second code retained in the electronically-readable memory, said second code being symbolic of a cumulative use of the web.
- 13. The module of claim 11, further comprising a second code retained in the electronically-readable memory, said second code being symbolic of a desired speed for moving the web relative to the fuser roll.
- 14. A method of operating a printing apparatus, comprising the steps of:
- providing a module separable from the digital printing apparatus, the module comprising a web suitable for treating a fuser roll, the web being movable relative to the fuser roll, and an electronically-readable memory;
- the digital printing apparatus reading at least a first code retained in the electronically-readable memory, said code being symbolic of a maximum use of the web.
- 15. The method of claim 14, the digital printing apparatus reading a second code retained in the electronically-readable memory, said second code being symbolic of a cumulative use of the web.
- 16. The method of claim 14, the digital printing apparatus reading a second code retained in the electronically-readable memory, said second code being symbolic of a desired speed for moving the web relative to the fuser roll.
