Abstract
Systems, methods, and devices are provided for detecting an ink drop crossing a plane of light.
Claims59
A detection apparatus for printhead adjustment, comprising:
- a first light source for producing a first plane of light;
- a second light source for producing a second plane of light;
- and
- a sensor for detecting an ink drop passing through at least one of the first and second planes of light.
1 more element
An adjustment apparatus, comprising:
- a light source for producing a plane of light;
- a sensor positioned to detect a position of an ink drop ejected from a nozzle of a printhead;
- and
- a processor to determine the position of the ink drop based on the detected position, wherein the detected position includes data received from the sensor that represents an x axis position and a y axis position of the ink drop on the plane of light.
1 more element
A method, comprising:
- determining a position of an ink drop within a plane of light based upon detecting the ink drop crossing the plane of light.
A method for ink ejection adjustment, comprising:
- detecting a number of ink drops passing through a plane of light;
- determining the position of each of the number of ink drops based upon the passing of each ink drop through the plane of light;
- measuring a positional difference between the number of ink drops based upon the determined position;
- and
- adjusting printhead ink ejection firing based upon the positional difference.
2 more elements
An image forming system, comprising:
- at least two printheads for ejecting ink drops;
- and
- an ink drop detection apparatus, including:
- a light source for producing a collimated plane of light;
- a sensor for detecting a position of the ink drops passing through the collimated plane of light;
- and
- a processor to determine the position of the ink drops based on the detected position of the ink drops.
4 more elements
An apparatus for printing, comprising:
- a light source and a sensor to provide data about positioning of a number of nozzles of at least two printheads;
- and
- means for determining a positional offset of the at least two printheads based on the data.
A computer readable medium having a set of executable instructions for causing a device to perform a method, comprising:
- detecting a number of ink drops passing through a plane of light;
- determining the position of each of the number of ink drops based upon the passing of each ink drop through the plane of light;
- measuring a positional difference between the number of ink drops based upon the determined position;
- and
- adjusting printhead ink ejection firing based upon the positional difference.
2 more elements
A computer readable medium having a set of executable instructions for causing a device to perform a method, comprising:
- determining a position of an ink drop within a plane of light based upon detecting the ink drop crossing the plane of light.
