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.

First claim

What is claimed:

1. 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.

2. The device of claim 1 , wherein the second roller is activated based on a determination of a first type of print media and not activated based on a determination of a second type of print media.

3. The device of claim 2 , wherein the first type of media exceeds a thickness threshold and the second type of media is less than the thickness threshold.

4. The device of claim 1 , wherein the first sensor is positioned at a start of a corner of a print media path and the second sensor is positioned at an end of the corner of the print media path.

5. The device of claim 4 , wherein the corner includes an inline scanning device positioned between the second roller and the second sensor.

6. The device of claim 1 , wherein the first roller remains activated when the second roller is activated.

7. The device of claim 1 , wherein the second roller is to provide the print media past a scanning device at a particular speed.

8. 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 the 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 the print media path, wherein the first drive motor is deactivated based on when the leading edge of the print media interacts with the second sensor.

9. The printing device of claim 8 , wherein the first drive motor and second drive motor are active in parallel.

10. The printing device of claim 8 , wherein the first roller is a first size and the second roller is a second size that is smaller than the first size.

11. The printing device of claim 8 , comprising a media type sensor to determine when the print media is the particular type of print media, wherein the particular type of print media exceeds a thickness threshold.

12. The printing device of claim 8 , wherein the first roller is positioned between the first sensor and a print media tray storing print media and the second roller is positioned between the first sensor and the second sensor.

13. 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.

14. The system of claim 13 , wherein the controller includes instructions to activate the scanning device when the leading edge of the print media is detected by the first sensor.

15. The system of claim 13 , wherein the set of rollers rotate at a first speed and the turn roller rotates at a second speed that is greater than the first speed.
