Abstract
The banner or cover sheet for a print job may be used for aperiodic sampling of transfer performance and/or fusing performance. Sensing pre-process and post-process is required. The resulting sampling is aperiodic and dependent on the job flow. In office products there is typically a frequent generation of cover sheets and the information collected in this way can be useful in system performance optimization. The concept is described for a tandem transfer system.
Claims24
An image processing method comprising:
- receiving a print job at an image forming device;
- generating a banner page for the print job;
- adding one or more test patterns to the banner page;
- sensing the test patterns on the banner page pre-transfer and/or post-transfer and generating image quality data;
- analyzing the image quality data for image quality defects;
- and
- adjusting at least one transfer setting for the image forming device based on the analysis of the image quality data.
An image processing apparatus comprising:
- an image forming device that receives a print job and adds one or more test patterns to a banner page for the print job;
- at least one sensor that senses the test patterns on the photoreceptor, intermediate transfer device, and/or banner page pre-transfer and/or post-transfer and generates image quality data;
- and
- an image processing controller that analyzes the data for printing defects and adjusts at least one transfer setting for the image forming device based on the analysis of the image quality data.
A computer program product comprising:
- a computer-usable data carrier storing instructions that, when executed by a computing device, cause the computing device to perform a method comprising:
- receiving a print job;
- generating a banner page for the print job;
- adding one or more test patterns to the banner page;
- sensing the test patterns on the banner page pre-transfer and/or post-transfer and generating image quality data;
- analyzing the image quality data for image quality defects;
- and
- adjusting at least one transfer and/or fuser setting for the printer based on the analysis of the image quality data.
An image processing method comprising:
- receiving a print job at an image forming device;
- generating a banner page for the print job;
- adding one or more test patterns to the banner page;
- sensing the test patterns on the banner page pre-fusing and/or post-fusing and generating image quality data;
- analyzing the image quality data for image quality defects;
- and
- adjusting at least one fusing setting for the image forming device based on the analysis of the image quality data.
