Abstract
In one example, image forming quality is stabilized by monitoring aging characteristics of an image forming system including its set of supplies. When an age-related triggering event occurs, a set of modified parameters are substituted for a set of standardized parameters. This substitution increases the image forming quality while sacrificing some visual acuity based on user preferences from psychometric testing.
Claims15
A method of open-loop stabilizing image forming quality, comprising:
- characterizing image degradation over time related to an image forming quality of an imaging forming device having a set of supplies;
- determining which of a set of standardized parameters are to be modified on an age-related trigger event to increase overall image forming quality to improve visual acuity beyond an acceptability threshold based on user preferences from psychometric testing;
- creating a set of modified parameters based on the age-related triggering event and the acceptability threshold;
- storing the set of standardized parameters and the set of modified parameters within a computer readable medium of the imaging forming device;
- and
- storing a set of instructions in the computer readable medium to allow a processor to read and execute the instructions when the age-related triggering event occurs to substitute the set of modified parameters for the standardized set of parameters.
An open-loop image forming system to stabilize image forming quality, comprising:
- a set of supplies used in forming an image;
- a non-transitory computer readable memory storing a set of standardized parameters and at least one set of modified parameters, each set related to image forming quality, the memory further including a set of instructions;
- a processor coupled to the memory and the set of supplies, the processor to execute the instructions wherein the instructions allow the processor to:
- monitor aging characteristics of the image forming system including the set of supplies;
- determine when an age-related triggering event occurs;
- substitute a respective set of modified parameters for the standardized set of parameters after the age-related triggering event occurs, wherein the overall image forming quality is increased while sacrificing some visual acuity based on user preferences from psychometric testing.
A non-transitory computer readable medium, comprising instructions to stabilize image forming quality, the instructions when read and executed by a processor cause the processor to:
- read and utilize a set of default parameters related to image forming quality of an image forming system haying a set of supplies;
- monitor wear and inefficiency characteristics of the image forming system and the set of supplies;
- determine when at least one of a wear and an inefficiency triggering event occurs;
- and
- when the at least one of the wear and the inefficiency triggering event occurs, substitute a set of healing parameters for the set of default parameters to increase the overall image forming quality to improve visual acuity beyond an acceptability threshold based on user preferences from psychometric testing, and wherein the image forming system does not include a dosed loop feedback system for monitoring and correcting image forming quality.
