A diagnostic method for color stability in an image printing system includes printing a test pattern onto output media; measuring, during the printing of the test pattern, an image of the test pattern on an image transfer surface using one or more image transfer surface sensors to obtain one or more image transfer surface signals; measuring a printed image of the test pattern on the output media using a printed image sensor to obtain a printed image signal; calculating correlation functions for the one or more image transfer surface signals and the printed image signal; and analyzing the correlation functions for the one or more image transfer surface signals and the printed image signal to identify a subsystem in the image printing system that causes variations in color within the plurality of prints of the test pattern.

A method of determining a probability of a set of print jobs being completed within a time period may include receiving a schedule associated with a set of print jobs. The schedule may include a sequence in which the set of print jobs is to be processed, a mean processing time associated with each print job in the set, and a standard deviation of a processing time associated with each print job in the set. The method may include determining a probability that a print shop will complete processing of the set of print jobs within a time period based on the mean processing time and standard deviation associated with each of the print jobs in the set that has not been processed and displaying the probability on a display device.
摘要:
A system that determines an amount of toner mass present on a toner application surface, and comprises a specular reflection sensor, a diffuse reflection sensor, an output combination module, and a mass determination module. The specular reflection sensor receives electromagnetic radiation that has been specularly reflected by the toner application surface, and generates a specular reflection output representative of the received electromagnetic radiation. The diffuse reflection sensor receives electromagnetic radiation that has been diffusely reflected by the toner application surface, and generates a diffuse reflection output representative of the received electromagnetic radiation. The output combination module creates a combined output by combining the specular reflection output and the diffuse reflection output with the purpose of reducing a noise source common to both specular and diffuse outputs to improve the signal to noise ratio. The mass determination module determines an amount of toner mass present on the toner application surface based on the combined output.

A method of assigning a job to a production device may include identifying a queue comprising a plurality of print jobs, identifying a plurality of print production devices capable of processing the plurality of print jobs, determining that one of the identified print production devices is an idle print production device, identifying a top priority print job from the queue, determining a completion time associated with processing the top priority print job by each of the identified print production devices, identifying a fastest print production device, assigning the top priority print job to the fastest print production device, determining whether the fastest print production device is the idle print production device, and in response to determining that the fastest print production device is the idle print production device, sending the top priority print job to the fastest print production device and removing the top priority print job from the queue.

摘要:
Methods and systems of balancing job assignments to a plurality of machines are disclosed. A computing device receives multiple jobs each having a job size and determines a job order for the jobs based on each job's job size. A machine order is determined for a plurality of machines based on a setup time and a processing rate associated with each machine. The computing device assigns one or more jobs to each machine based on the job order and the machine order such that a maximum total processing time for the machines is minimized. A total processing time for each machine is determined based on the number of jobs and the cumulative job size of the jobs assigned to the machine, and the setup time and the processing time associated with the machine. The maximum total processing time is the largest of the total processing times for the machines.
