Abstract

A printing device ( 100, 200 ) may include a carriage ( 101, 201 ) to hold an integrated printhead ( 103, 203 ) in the printing device; a manifold latch ( 105, 205 ) to connect the integrated printhead and an ink tank connector in a locked position; and a controller ( 109, 209 ) to align the carriage within the printing device based on a level of health of the integrated printhead and a latching position of the manifold latch. Furthermore, a non-transitory computer readable medium and a printing method are disclosed.

Claims (49)

1. A printing device, comprising:

a carriage to hold an integrated printhead in the printing device;

a manifold latch to connect the integrated printhead and an ink tank connector in a locked position; and

a controller to:

align the carriage within the printing device, based on a level of health of the integrated printhead and a latching position of the manifold latch.

2. The printing device of claim 1 , including the controller to:

determine if the manifold latch is in an opened or closed position.

3. The printing device of claim 1 , including the controller to align the carriage in a pen present position, in response to a determination that the manifold latch is in an open position.

4. The printing device of claim 1 , including the controller to align the carriage in a pen present position, in response to a determination that:

the manifold latch is in a closed position; and

a pen body in the integrated printhead has an error.

5. The printing device of claim 1 , including the controller to align the carriage in a capped position, in response to a determination that:

the manifold latch is in a closed position; and

a pen body in the integrated printhead does not have an error.

6. The printing device of claim 1 , further including the controller to:

determine a level of health of the integrated printhead; and

move a position of the carriage based on the manifold latch position and the level of health of the integrated printhead.

7. A non-transitory computer readable medium containing instructions executable by a processor to:

determine a level of health of a pen body in an integrated printhead; and

align a carriage, that includes the integrated printhead and a manifold latch, in a particular position within a printing device based on the determined level of health of the pen body and a latching position of the manifold latch.

8. The medium of claim 7 , wherein the instructions to determine the level of health of the pen body include instructions to:

read pen data relating to a historical functioning of the pen body; and

determine the level of health of the pen body based on the read pen data.

9. The medium of claim 7 , wherein the instructions to determine the level of health of the pen body include instructions to:

initiate an image quality check, in response to a determination that no error was reported in pen data relating to a historical functioning of the pen body.

10. The medium of claim 7 , wherein the instructions to determine the level of health of the pen body include instructions to:

determine that the pen body has an error, in response to a determination that:

the pen body has failed within a specified period of time;

the pen body is missing; or

a threshold number of nozzles on the pen body are damaged.

11. The medium of claim 7 , wherein the instructions to determine the level of health of the pen body include instructions to:

determine that the pen body has an acceptable level of health, in response to:

a determination that no error is in read pen data relating to historical functioning of the pen body; and

a determination that a printed pen health page passed an image quality check.

12. A method comprising:

determining that a door of a printing device is in an open position;

determining a position of a manifold latch on a carriage of the printing device in response to the determination that the door is open; and

aligning the carriage in a particular location within the printing device based on the determined manifold latch position.

13. The method of claim 12 , further comprising:

determining a level of health of an integrated printhead inserted in the carriage;

wherein aligning the carriage in a particular location includes moving the carriage to the particular location based on the determined manifold latch position and the level of health of the integrated printhead.

14. The method of claim 12 , wherein aligning the position of the carriage includes:

aligning the carriage in a pen present position in response to:

determining that the manifold latch is in a closed position; and

determining that a component of the integrated printhead has an error.

15. The method of claim 12 , wherein maintaining the position of the carriage includes:

maintaining the carriage in a capped position in response to:

determining that the manifold latch is in a closed position; and

determining that a component of the integrated printhead does not have an error.
