Claims

1. Lateral adjustment apparatus comprising:

a gripper to grip a print substrate, the gripper being mounted on a rotor rotatable about a lateral axis; and

a lateral adjustment motor to drive movement of the gripper laterally along the rotor to adjust a lateral position of the print substrate;

wherein the lateral adjustment motor is mounted on the rotor.

2. Lateral adjustment apparatus according to claim 1 , wherein the lateral adjustment motor is electrically connected to a power supply by way of a slip ring.

3. Lateral adjustment apparatus according to claim 1 , wherein the lateral adjustment motor is within a lateral extent of the gripper.

4. Lateral adjustment apparatus according to claim 1 , wherein the lateral adjustment motor is located in the same region of a housing as the gripper.

5. Lateral adjustment apparatus according to claim 1 , wherein the lateral adjustment motor is mounted on the rotor so as to rotate together with the rotor.

6. Lateral adjustment apparatus according to claim 1 , wherein the gripper is mounted on the rotor by way of being movably mounted on a rail and the lateral adjustment motor is to drive movement of the gripper laterally along the rail.

7. Lateral adjustment apparatus according to claim 1 , wherein the lateral adjustment motor is operatively coupled to the gripper by way of a ball screw.

8. Lateral adjustment apparatus according to claim 1 further comprising a rotor motor to drive rotation of the rotor and/or a gripper motor to drive actuation of the gripper, the gripper motor being mounted on the rotor.

9. A printing device comprising lateral adjustment apparatus, the lateral adjustment apparatus comprising:

a gripper to grip a print substrate, the gripper being mounted on a rotor rotatable about a lateral axis; and

a lateral adjustment motor to drive movement of the gripper laterally along the rotor to adjust a lateral position of the print substrate;

wherein the lateral adjustment motor is mounted on the rotor.

10. A printing device according to claim 9 further comprising:

a camera to capture an image of at least a portion of the print substrate; and a controller to determine a location of the substrate from the image to determine a distance of the print substrate from a predetermined location.

11. A printing device according to claim 10, wherein the controller is to control the lateral adjustment apparatus to adjust the lateral position of the print substrate based on the determined distance of the print substrate from the predetermined location.

12. A printing device according to claim 10, wherein the controller is to determine a location of a portion of a side edge of the print substrate or a location of a corner of the print substrate from the captured image and to control the lateral adjustment apparatus to adjust the lateral position of the print substrate such that the portion of the side edge of the print substrate or the corner of the print substrate is relocated to a predetermined location.

13. A printing device according to claim 9 further comprising feed apparatus and print apparatus, the lateral adjustment apparatus being located between the feed apparatus and the print apparatus.

14. The printing device according to claim 13, wherein the feed apparatus comprises skew correction apparatus to rotate the print substrate to correct skew.

15. Lateral adjustment apparatus comprising:

a rotor rotatable about a lateral axis;

a gripper to grip a print substrate, the gripper being movably mounted on the rotor by way of a laterally extending rail;

a lateral adjustment motor, mounted on the rotor, to drive lateral movement of the gripper along the rail; and

a rotor motor to drive rotation of the rotor about the lateral axis.
