Abstract

A mobile device comprising: a printhead for printing onto a media substrate; a media feed path for feeding the media substrate past the printhead; and, a collection facility for holding the media substrate after printing.

Claims

1. A mobile device comprising:

a printhead for printing onto a media substrate;

a media feed path for feeding the media substrate past the printhead; and

,

a collection facility for holding the media substrate after printing.

2. A mobile device according to claim 1 further comprising:

first and second body sections movable relative to each other into an operative configuration and an inoperative configuration;

wherein,

the media feed path extends from the first body section into the second body section when in the operative configuration.

3. A mobile device according to claim 1 wherein the media feed path in linear when the first and second body sections are in the operative configuration.

4. A mobile device according to claim 1 wherein the first body section is hinged to the second body section.

5. A mobile device according to claim 1 wherein the first body section is slidably connected to the second body section.

6. A mobile device according to claim 1 wherein the first body section has a storage facility for the media substrate and the printhead is positioned between the storage facility and the collection facility.

7. A mobile device according to claim 1 wherein the printhead has an array of nozzles for printing a media substrate;

a capper assembly movable between a capped position covering the nozzles and an uncapped position spaced from the nozzles;

wherein,

the capper assembly is held in the uncapped position by the media such that it moves to the capped position upon disengagement with the media.

8. A mobile device according to claim 1 wherein the sheet of media substrate is encoded and the print engine controller uses an optical sensor to determine the position of the sheet relative to the printhead.

9. A mobile device according to claim 1 further comprising a drive shaft for feeding the media past the printhead.

10. A mobile device according to claim 1 wherein the media substrate is a sheet and the trailing edge of the sheet disengages from the drive shaft before it is printed and is projected past the printhead by its momentum.

11. A mobile device according to claim 4 wherein the capper assembly lightly grips the sheet after it has been printed so that it partially extends from the mobile telecommunications device in readiness for manual collection.

12. A mobile device according to claim 5 wherein the capper assembly moves out of the capped position and toward the uncapped position upon engagement with the leading edge of the sheet.

13. A mobile device according to claim 1 wherein the printhead is incorporated into a cartridge that further comprises a print media feed path for directing the print media past the printhead in a feed direction during printing, and a drive mechanism for driving the print media past the printhead for printing.

14. A mobile device according to claim 1 wherein the printhead has an array of ink ejection nozzles and is incorporated into a cartridge that further comprises at least one ink reservoir for supplying ink to the printhead for ejection by the nozzles, each of the at least one ink reservoirs including at least one absorbent structure for inducing a negative hydrostatic pressure in the ink at the nozzles, and a capping mechanism for capping the printhead when not in use.

15. A mobile device according to claim 1 further comprising:

(a) a print media feed path for directing print media past the printhead in a feed direction during printing;

(b) a capping mechanism including a capper moveable between a capping position in which the capper is urged into a capping relationship with the printhead, and an uncapped position in which the printhead is able to print onto the print media, wherein in the uncapped position the capper is displaced away from the printhead; and

(c) a force transfer mechanism connected to the capper and configured such that a force provided by an edge of the media as it moves relative to the feed path is transferred to the capper by the force transfer mechanism, thereby to at least commence movement of the capper from the capped position to the uncapped position prior to the media reaching the capper.

16. A mobile device according to claim 1 further comprising:

(a) a print media feed path for directing print media past the printhead in a feed direction during printing;

(b) a capping mechanism including a capper moveable between a capping position in which the capper is urged into a capping relationship with the printhead, and an uncapped position in which the printhead is able to print onto the print media, wherein in the uncapped position the capper is displaced away from the printhead;

(c) a locking mechanism configured to hold the capper in the uncapped position until after a trailing edge of the media is clear of the printhead.

17. A mobile device according to claim 1 wherein the drive assembly has a drive shaft with a media engagement surface for feeding a media substrate along a feed path;

and,

a media guide adjacent the drive shaft for biasing the media substrate against the media engagement surface.

18. A mobile device according to claim 1 further comprising:

a drive shaft for feeding the sheet of media substrate past the printhead;

wherein during use,

the sheet disengages from the drive shaft before completion of its printing such that the trailing edge of the sheet projects past the printhead by momentum to complete its printing.

19. A mobile device according to claim 1 wherein the printhead comprises:

an array of nozzles for ejecting ink;

print data circuitry for providing the nozzles with print data; and

,

a photosensor for optically receiving the print data from a beacon operated by a print engine controller.

20. A mobile device according to claim 1 further comprising:

a drive shaft for feeding the sheet of media substrate past the printhead and a drive system to rotate the drive shaft;

wherein,

the drive system rotates the drive roller by friction.
