Abstract
Examples for estimating quantity of print media available in a device, are described. In one example, the device comprising includes a series of proximity sensors to sense level of a stack of print media. The sensors are mounted on an internal vertical wall of the media tray with each of the plurality of sensors mounted at a different vertical height. Based on the sensing by the sensors, an estimate count of the print media available in a media tray of the device is generated.
Claims14
A device comprising:
- a media tray to store a stack of print media;
- a series of sensors mounted on an internal vertical wall of the media tray with each of the plurality of sensors mounted at a different vertical height, wherein each of the series of sensors is to sense level of the stack of print media;
- and
- a media count engine coupled to the series of sensors, wherein the media count engine is to:
- generate an estimate count of the print media available in the media tray based on the sensing by any one of the series of sensors;
- determine a number of print media utilized for a rendering operation;
- and
- in response to the determining, update the estimate count of the print media available in the media tray.
A method comprising:
- ascertaining position of a print media within a media tray of a device at an initial level through an initial sensor from amongst of a series of sensors, wherein the series of proximity sensors are mounted on an internal vertical wall of the media tray with each of the plurality of sensors mounted at a different vertical height;
- detecting a next lower level of stack of the print media by a next lower sensor from amongst the series of sensors;
- determining a preliminary count based on quantity of print media utilized between the initial level and the next lower level during processing of a rendering operation;
- and
- generating an estimate count of the print media based on a value of the preliminary count and a number of sensors positioned beneath the initial sensor.
A non-transitory computer-readable medium comprising instructions executable by a processing resource to:
- ascertain position of a print media within a media tray of a device at an initial level based on proximity of the print media from an initial sensor from amongst a series of sensors, wherein the series of proximity sensors are mounted on an internal vertical wall of the media tray with each of the plurality of sensors mounted at a different vertical height;
- detect another next lower level of stack of the print media by a next lower sensor from amongst the series of sensors;
- determine a preliminary count based on quantity of print media utilized between the initial level and the another next lower level for processing a rendering operation;
- and
- generate an estimate count of the print media based on a value of the preliminary count and a number of sensors positioned beneath the initial sensor.
