Claims
- 1. A method for operating a machine comprising the steps of:providing a replaceable sub-assembly separable from the machine, the replaceable sub-assembly further comprising a memory, the memory having stored within a software code upgrade of executable instructions relating to the utilization of the replaceable sub-assembly responsive to a design variance in the customer replaceable unit; placing the replaceable sub-assembly into the machine; reading the memory and placing the stored software code upgrade into the machine as new executable instructions; and operating the machine with the replaceable sub-assembly in accordance with the new executable instructions.
- 2. The method of claim 1 wherein the machine is a printing apparatus.
- 3. The method of claim 2 wherein the replaceable sub-assembly is a CRU.
- 4. The method of claim 3 wherein the memory is a non-volatile type of memory.
- 5. The method of claim 4 wherein the memory is a CRUM.
- 6. The method of claim 2 wherein the software code upgrade of executable instructions includes parameter arguments.
- 7. A replaceable sub-assembly for use in a machine at various setpoints comprising:a memory; and upgraded executable instruction suitable for directing the machine to use the replaceable sub-assembly with different setpoints responsive to a design variance in the customer replaceable unit, where the upgraded executable instruction is stored in the memory.
- 8. The replaceable sub-assembly of claim 7 wherein the machine is a printing apparatus.
- 9. The replaceable sub-assembly of claim 8 wherein the replaceable sub-assembly is a CRU.
- 10. The replaceable sub-assembly of claim 9 wherein the memory is non-volatile memory.
- 11. The replaceable sub-assembly of claim 10 wherein the memory is a CRUM.
- 12. The replaceable sub-assembly of claim 9 wherein the CRU is a print cartridge.
- 13. The replaceable sub-assembly of claim 12 wherein the setpoints relate to photoreceptor aging rate, machine temperature and machine humidity.
- 14. A method for operating a printer apparatus comprising the step of:providing a customer replaceable unit separable from the printer apparatus, the customer replaceable unit further comprising a memory, the memory having stored within a software code upgrade of executable instructions relating to the utilization of the customer replaceable unit responsive to a design variance in the customer replaceable unit.
- 15. The method of claim 14 wherein the memory is non-volatile in type.
- 16. The method of claim 15 wherein the memory is a CRUM.
- 17. The method claim of 16 further comprising the step of operating the printer apparatus in accordance with the software code upgrade of executable instructions.18.The method claim of 16 further comprising the steps of:reading the CRUM and placing the stored software code upgrade of executable instructions into the printer apparatus as new executable instructions; and operating the printer apparatus in accordance with the new executable instructions.
- 19. The method of claim 16 wherein the customer replaceable unit is a printer cartridge.
- 20. The method of claim 19 wherein the software code upgrade of executable instructions comprise equations utilized to calculate charge voltage, developer housing bias voltage, and ROS imaging exposure level as a function of photoreceptor age in cycles of machine temperature and machine humidity.
- 21. The method of claim 16 wherein the customer replaceable unit is a toner cartridge.
- 22. The method of claim 16 wherein the software code upgrade of executable instructions includes parameter arguments.
- 23. The method of claim 22 wherein the parameter arguments relate to photoreceptor aging rate, machine temperature and machine humidity.
