Abstract
The disclosure proposes the automatic use of the job or image content information of a print job. This information is used to automatically adjust the general printing procedure for a print engine. The job's image content information is analyzed in the context of the constraints of the print engine to determine an improved printing procedure, which may include cycle-up operation, process control cycles, or maintenance cycles for that particular print job.
Claims20
A method of operating a print engine, comprising:
- receiving a print job in a print queue;
- analyzing image content of the print job, wherein analyzing the image content comprises identifying maximum size of mid-level halftone blocks for each color separation, susceptibility to halftone depletion surrounding text, susceptibility to reload defects, or susceptibility to ghosting;
- determining a printing procedure for a print engine based on the image content;
- printing, via the print engine, the print job using the determined printing procedure;
- using the image content to determine a maintenance cycle interval for the print engine;
- adjusting a frequency of a maintenance cycle for the print engine based on the determined maintenance cycle interval;
- and
- performing a maintenance event in the print engine according to the adjusted maintenance cycle.

A method of operating a print engine, comprising:
- receiving a first print job in a print queue;
- analyzing image content comprising data selected from the group consisting of regions of susceptibility to ghosting or reload defect, and maximum size of mid-level halftone blocks for each color separation;
- determining a printing procedure for a print engine based on the image content of the first print job in the print queue;
- receiving a second print job in the print queue;
- analyzing image content comprising data selected from the group consisting of regions of susceptibility to ghosting or reload defect, and maximum size of mid-level halftone blocks for each color separation;
- modifying the printing procedure for the print engine based on the image content of the second print job;
- printing, via the print engine, the first and second print jobs using the modified printing procedure;
- adjusting a frequency of a maintenance cycle for the print engine based on the image content of the first and second print jobs;
- and
- performing a maintenance event in the print engine based on the adjusted maintenance cycle.

A method of operating a print engine, comprising:
- receiving a first print job in a print queue;
- analyzing image content for the first print job by identifying maximum size of mid-level halftone blocks for each color separation, susceptibility to halftone depletion surrounding text, susceptibility to reload defects, or susceptibility to ghosting in the first print job;
- determining, via a processor, a printing procedure for the print engine based on the image content of the first print job in the print queue, wherein the printing procedure comprises a cycle-up printing procedure or a process control cycle;
- receiving a second print job in the print queue;
- analyzing image content of the second print job by identifying maximum size of mid-level halftone blocks for each color separation susceptibility to halftone depletion surrounding text, reload defects, or susceptibility to ghosting in the second print job;
- modifying the printing procedure for the print engine based on the image content of the second print job;
- printing, via the print engine, the first and second print jobs using the modified printing procedure;
- determining a maintenance cycle for the print engine based on the image content of the first and second print jobs;
- and
- performing a maintenance event in the print engine based on the maintenance cycle.
