## 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

### Claim 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.

### Claim 2 (depends on 1)

The printing device of claim 1, including the controller to:
determine if the manifold latch is in an opened or closed position.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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.

### Claim 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.

### Claim 8 (depends on 7)

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.

### Claim 9 (depends on 7)

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.

### Claim 10 (depends on 7)

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.

### Claim 11 (depends on 7)

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.

### Claim 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.

### Claim 13 (depends on 12)

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.

### Claim 14 (depends on 12)

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.

### Claim 15 (depends on 12)

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.
