Abstract
A method adjusts operation of a printer in accordance with an analysis of image content used to generate printed images. The method includes measuring image content of a first print image, comparing the measured image content to a predetermined threshold, and altering a print process parameter to adjust operation of a printer component in response to the measured image content exceeding the threshold.
Claims19
A method for optimizing the print process of an ink jet printer comprising:
- measuring image content of a first print image;
- comparing the measured image content to a predetermined threshold;
- altering a print process parameter to adjust operation of a printer component in response to the measured image content exceeding the threshold;
- detecting a duplex print image;
- and
- the alteration of the print process parameter includes modifying rotational speed of an image receiving member for a release agent application in response to the measured image content exceeding the predetermined threshold.
A method for optimizing a printing process of an ink jet printer comprising:
- measuring image content for a first print image;
- comparing the measured image content for the first print image to a first predetermined threshold;
- and
- altering a rotational speed of an image receiving member for a release agent application in response to the measured image content exceeding the predetermined threshold.
An ink jet printer having multiple transfixing modes and multiple release agent application modes comprising:
- a rotatable image receiving member having a coating of release agent thereon;
- a print head adjacent said rotatable image receiving member for ejecting ink droplets thereon to form ink images on said rotatable image receiving member, said ink images having a top edge;
- a transfix roll located adjacent said rotatable image receiving member and downstream from said print head, the transfix roll being adapted for movement towards and away from said rotatable image receiving member in order to form a transfixing nip periodically with the rotatable image receiving member;
- a release agent applicator configured to selectively engage the rotatable image receiving member to apply release agent to the rotatable imaging member;
- and
- a controller configured to analyze image content of at least one print image and to alter rotational speed of the rotatable image receiving member for a release agent application in response to the image content of the at least one print image exceeding a predetermined threshold.
