Abstract
Example implementations relate to print media rollers. For example, implementations can include a device that includes a first roller to receive print media, a first sensor to determine when a leading edge of the print media is at a first location, a second roller to be activated based on a type of the print media and when the leading edge of the print media interacts with the first sensor, a second sensor to determine when the leading edge of the print media is at a second location, wherein the first roller is deactivated based on when the leading edge of the print media interacts with the second sensor.
Claims15
A device, comprising:
- a first roller to receive print media;
- a first sensor to determine when a leading edge of the print media is at a first location;
- a second roller to be activated based on a type of the print media and when the leading edge of the print media interacts with the first sensor;
- a second sensor to determine when the leading edge of the print media is at a second location, wherein the first roller is deactivated based on when the leading edge of the print media interacts with the second sensor.
A printing device, comprising:
- a first roller coupled to a first drive motor to be activated to move print media along a print media path;
- a first sensor at a first location of the print media path to determine when a leading edge of the print media is at the first location of the print media path;
- a second roller coupled to a second drive motor to be activated to move print media along the print media path when the print media is a particular type of print media and the print media is sensed by the first sensor;
- and
- a second sensor at a second location of the print media path to determine when the leading edge of the print media is at the second location of the print media path.
A system, comprising:
- a print media path between a print media tray and a print zone;
- a set of rollers coupled to a first motor;
- a turn roller coupled to a second motor;
- a first sensor positioned between the set of rollers and the turn roller;
- a second sensor positioned between the turn roller and a feed roller;
- a scanning device positioned inline with the print media path between the turn roller and the second sensor;
- and
- a controller, comprising instructions to:
- activate the set of rollers to provide print media to the print media path;
- determine the print media exceeds a thickness threshold;
- activate the turn roller when a leading edge of the print media is detected by the first sensor;
- activate the scanning device to scan the print media when the print media passes the scanning device through the print media path;
- and
- deactivate the set of rollers when the leading edge of the print media is detected by the second sensor.
