Abstract
A process is implemented in a printer having a release agent application system that enables a controller in the printer to detect gel ink in the release agent application system exceeding a predetermined threshold. The process monitors a plurality of print characteristics with reference to print data and quantifies a risk of gel ink developing in the release agent application system. The print characteristics include a print area value identifying a total surface area of a print, an inked area value identifying an area of surface area covered with ink, and a print type indicating whether the print is a simplex print or a duplex print.
Claims23
A method of monitoring a release agent application system of an imaging device, the method comprising:
- identifying a plurality of print characteristics for a print to be printed by an imaging device;
- generating a print gel score with reference to the plurality of print characteristics;
- adding the print gel score to an overall gel score for a release agent application system of the imaging device;
- comparing the overall gel score to a predetermined gel score threshold;
- and
- modifying operation of the imaging device in response to the comparison indicating that the overall gel score is greater than the predetermined gel score threshold.
A method of monitoring a release agent application system of an imaging device, the method comprising:
- identifying a plurality of print characteristics for a print performed by an imaging device, the plurality of print characteristics including a print area value identifying a total surface area of the print, an inked area value identifying an area of the surface area covered with ink, and a print type indicating whether the print is a simplex print or a duplex print;
- incrementing a total simplex print area value and a total simplex inked area value in response to the print type indicating that the print is a simplex print;
- incrementing a total duplex print area value and a total duplex inked area value in response to the print type indicating that the print is a duplex print;
- generating a simplex gel score with reference to the total simplex print area value and the total simplex inked area value;
- generating a duplex gel score with reference to the total duplex print area value and the total duplex inked area value;
- summing the simplex gel score and the duplex gel score to generate an overall gel score;
- comparing the overall gel score to a predetermined gel score threshold;
- and
- modifying operation of the imaging device in response to the comparison to the predetermined gel score threshold indicating the overall gel score is greater than the gel score threshold.
A method for detecting a likelihood of gel ink developing in a release agent application system within an inkjet printer comprising:
- identifying a plurality of print characteristics from print data used to operate ink ejecting devices in the inkjet printer;
- identifying a risk of gel ink developing in the release agent application system with reference to the identified plurality of print characteristics;
- and
- operating the inkjet printer with reference to the identified risk.
