Abstract

An image forming system (210) includes an engine controller (60) and memory device (152) with a power supply (162) supporting a 220 volt, 120 volt or 100 volt level. A fuser control capability indicator (164) is read by the engine controller (60) in order to determine the fuse control capabilities supported by the power supply (162) and, in conjunction, with a geographic region indicator of the system (210), a determination is made as to the appropriate fuser control process to adopt based on the geographic region in which the system (210) is used.

Claims

1. A method of determining geographic specific fuser control for image forming system, the method comprising the steps of:

determining the fuser control capabilities provided by an output from a power supply supplying power to the image forming system, said output comprising a fuser control indicator signal from said power supply corresponding to a fuser control process supported by said power supply;

reading a stored configuration identification parameter related to the geographic specifics of the image forming system;

from both the fuser control indicator signal and the stored configuration identification parameter, determining what type of fuser control process to use for the image forming system; and

wherein said step of determining the fuser control capabilities further comprises the step of determining the voltage level of said power supply by reading said signal provided by said power supply.

2. The method of claim 1 wherein the step of determining the fuser control process to use involves determining whether to use phase control or integer half cycle control for controlling a fuser of the image forming system.

3. The method of claim 1 wherein the step of determining the fusing control process to use involves determining whether to enable or disable a ready mode of the image forming system.

4. The method of claim 1 wherein the step of determining the fuser control process involves setting the ramp rate of the fuser.

5. The method of claim 1 wherein the step of determining the fuser control process to use involves setting at least one parameter of an algorithm for controlling a fuser within the image forming system.

6. The method of claim 5 wherein said parameter is the temperature set point of said fuser.

7. The method of claim 1 further comprising the step of determining if the signal is characteristic of a 120-volt or 220-volt power supply.

8. The method of claim 7 further comprising the step of using a phase control for controlling the fuser if the signal is characteristic of a 120 volt power supply.

9. The method of claim 7 further comprising the step of using an integer half cycle control for controlling the fuser if the signal is characteristic of a 220 volt power supply.

10. The method of claim 1 wherein said reading step further comprises the step of accessing a memory location within a memory device of said image forming system to retrieve said configuration identification parameter.

11. The method of claim 10 wherein said identification parameter identifies the type of operator panel installed on the image forming system.

12. The method of claim 10 wherein said identification parameter identifies the geographic specificity of said image forming system.

13. The method of claim 11 further comprising the step of determining from the type of operator panel installed if the image forming system is a Japanese model.

14. The method of claim 13 further comprising the step of disabling a ready mode of the image forming system if the operator panel is a Japanese model.

15. For an image forming system having a fuser and a memory device for storing information about the image forming system, a method of determining geographic related fuser control, the method comprising the steps of:

reading a stored configuration identification parameter specifying a configuration of the image forming system;

determining the fuser control capabilities provided by an output from a power supply supplying power to the image forming system, said output comprising a fuser control indicator signal from said power supply corresponding to a fuser control process supported by said power supply;

using both the fuser control indicator signal and the stored configuration identification parameter, determining what type of fuser control process to use for controlling how power is applied to a fuser of the image forming system; and

further comprising the step of disabling a fuser ready mode of the image forming system where the configuration identification parameter reflects that the image forming system is a Japanese model.

16. The method of claim 15 wherein the step of determining the fuser control process to use involves determining whether to use phase control or integer half cycle control for controlling the fuser of the image forming system.

17. The method of claim 15 wherein said reading and determining steps are performed when said image forming system is powering up.

18. The method of claim 15 further comprising the step of using a phase control process when the fuser control capabilities indicate a voltage of approximately 120 volts is being used by the image forming system.

19. The method of claim 15 further comprising the step of using an integer half cycle control process when the fuser control capabilities indicate a voltage of approximately 220 volts is being used by the image forming system.

20. The method of claim 15 further comprising the step of storing a set of control parameters in a memory device of said image forming system, the control parameters indicative of the type of fuser control process determined for use by said image forming system.

22. The method of claim 21 further comprising the step of turning the fuser off if the control parameters indicate the ready mode of the image forming system has been disabled.

23. The method of claim 15 wherein the step of determining the fuser control process to use involves a step selected from the group consisting of:

determining whether to use phase control or integer half cycle control for controlling the fuser, setting the ramp rate of the fuser, setting at least one parameter of an algorithm for controlling the fuser, and setting the temperature set point of said fuser.

24. An image forming system supporting geographic specific fuser control comprising:
