Abstract

Claims (29)

1. A printer apparatus comprising:

a media support attached to the printer apparatus at a media-support attachment point;

a printhead having an array of print elements configured to print sequential segments of an image on corresponding sequential segments of a print media, wherein the array of print elements define a lateral print axis;

a platen roller configured to advance the print media when printing the sequential segments; and

a verifier that is configured to verify a print output by the printer apparatus based on a digital representation of print output of the printer apparatus, the verifier comprising a verifier-coupling that is configured to engage, at least in part by a magnetic force, with a printer-coupling in the printer apparatus, wherein the verifier further comprises an image sensor having an array of photo sensors configured to capture the digital representation of the print output of the printer apparatus, wherein the print output of the printer apparatus comprises at least a portion of the sequential segments of the image printed on the print media, and wherein the magnetic force is configured such that it aligns the array of photo sensors to a fixed scanning position relative to the array of print elements.

2. The printer apparatus of claim 1 , wherein at least one of the verifier-coupling and the printer-coupling comprising one or more electromagnets that facilitate the coupling of the verifier to the printer apparatus at least in part by the magnetic force.

3. The printer apparatus of claim 1 , wherein the array of photo sensors are in the fixed scanning position in an instance in which the array of photo sensors are substantially parallel to the lateral print axis.

4. The printer apparatus of claim 2 , wherein the verifier comprises one or more protrusions and a verifier receiving space comprises one or more recesses corresponding to the one or more protrusions, each of the one or more protrusions being configured to fittingly mate with the respective one or more recesses.

5. The printer apparatus of claim 4 , wherein the verifier comprises the one or more electromagnets and the verifier receiving space comprises a magnetic material, the one or more electromagnets interacting with the magnetic material.

6. The printer apparatus of claim 4 , wherein the verifier receiving space comprises the one or more electromagnets and the verifier comprises a magnetic material, the one or more electromagnets interacting with the magnetic material.

7. The printer apparatus of claim 4 , wherein the verifier further comprises one or more verifier-fittings, and the verifier receiving space further comprises one or more printer-fittings, the one or more verifier-fittings and the one or more printer-fittings respectively configured to fittingly mate with one another.

8. The printer apparatus of claim 3 , wherein the array of photo sensors are in the fixed scanning position in an instance in which a photo sensor reference point corresponding to the array of photo sensors substantially is aligned laterally with a print axis reference.

9. The printer apparatus of claim 8 , wherein the photo sensor reference point is positioned substantially at a fixed distance from a media support reference point corresponding to the media support of the printer apparatus.

10. A method of removably coupling a verifier to a printer, the method comprising:

receiving the verifier that is configured to verify a print output by the printer based on a digital representation of the print output of the printer, wherein receiving the verifier further comprises positioning a verifier-coupling in proximity to a printer-coupling; and

coupling the verifier to the printer at least in part by a magnetic force acting between the verifier-coupling and the printer-coupling, wherein the verifier-coupling interacts with a printer-coupling metallic material at least in part by the magnetic force, wherein the magnetic force is configured such that it aligns an image sensor of the verifier to a fixed scanning position relative to an array of print elements of a printhead in the printer, wherein the image sensor comprises an array of photo sensors, and wherein the image sensor is configured to capture the digital representation of the print output of the printer.

11. The method of claim 10 , wherein the verifier-coupling comprises one or more electromagnets that are positioned to interact with the printer-coupling metallic material.

12. The method of claim 10 , wherein the image sensor having an array of photo sensors is configured to capture the digital representation of print output, wherein the print output comprises at least a portion of sequential segments of an image printed on a print media.

13. The method of claim 10 , wherein the verifier further comprises one or more protrusions configured to fittingly mate with respective one or more recesses defined in a verifier receiving space of the printer.

14. The method of claim 13 , wherein the verifier further comprises one or more verifier-fittings configured to fittingly mate with respective one or more printer-fittings of the verifier receiving space of the printer.

15. A method comprising:

generating a digital representation of a print output by a verifier, wherein the digital representation of the print output is generated by an image sensor of the verifier that is removably coupled to a printer at least in part by a magnetic force, wherein the magnetic force is configured such that it aligns the image sensor to a fixed scanning position relative to an array of print elements in a printhead of the printer;

comparing, using a processor, the digital representation of the print output to an input image provided by a print logic of the printer to generate a verification; and

determining that at least one predetermined standard is satisfied based on the verification.

16. The method of claim 15 , wherein the verifier is removably coupled to the printer using one or more magnets configured to supply a magnetic force.

17. The method of claim 16 , wherein the removably coupled printer comprises:

the array of print elements configured to print sequential segments of an image on corresponding sequential segments of a print media, wherein the array of print elements define a lateral print axis; and

a platen roller configured to advance the print media when printing the sequential segments.

18. The method of claim 17 , wherein the digital representation of the print output is generated by the image sensor having an array of photo sensors, wherein the print output of the removably coupled printer comprises at least a portion of the sequential segments of the image printed on the print media.
