Abstract

A fluid ejector includes a drop size symbol that is based on the fluid ejector'"'"'s drop size relative to one or more fixed drop sizes. The drop size symbol is formed by comparing the fluid ejector'"'"'s drop size to the one or more fixed drop sizes. An image forming device includes a marking fluid ejector that includes a drop size symbol based on the marking fluid ejector'"'"'s drop size relative to one or more fixed drop sizes. The image forming device forms an image based on the drop size symbol by determining the drop size symbol and then either selecting a marking fluid look-up table based on the drop size symbol, or forming an image correction factor based on the drop size symbol.

Claims

1. A method for an image forming device to form an image based on a drop size symbol, the image forming device including a marking fluid ejector that is arranged to eject at least one marking fluid drop of a drop size and that includes a drop size symbol based on the drop size, comprising the steps of:

(a) determine the drop size symbol; and

(b) select at least one marking fluid look-up table based on the drop size symbol, thus forming a selected at least one marking fluid look-up table,

where the image forming device comprises a plurality of marking fluid look-up tables based on a range of marking fluid drop sizes.

2. The method of claim 1, including the subsequent steps of:

(c) provide an image information; and

(d) form a marking fluid information based on the image information and the selected at least one marking fluid look-up table.

3. The method of claim 2 including a subsequent step of:

(e) form an image based on the marking fluid information.

4. The method of claim 1, the marking fluid ejector including a storage means, the drop size symbol being disposed in the storage means, the drop size symbol determining step (a) including a step of accessing the storage means.

5. The method of claim 1, the marking fluid ejector comprising a radio frequency tag with the drop size symbol disposed therein, the drop size symbol determining step (a) including a step of detecting at least one radio frequency communication.

6. The method of claim 1, the marking fluid ejector comprising a housing exterior with a drop size symbol being disposed thereon, the drop size symbol determining step (a) including a step of detecting the at least one symbol.

7. The method of claim 6 the drop size symbol being machine-detectable.

8. The method of claim 6 the drop size symbol forming part of a marking fluid ejector identification code or serial number.

9. The method of claim 3, the image information including at least one of a red, green and blue image information.

10. The method of claim 9 the marking fluid information including at least one of a cyan, magenta, yellow and black colorant information.

11. A method for an image forming device to form an image based on a drop size symbol, the image forming device including a marking fluid ejector that is arranged to eject at least one marking fluid drop of a drop size and that includes a drop size symbol based on the drop size, comprising the steps of:

(a) determine the drop size symbol; and

(b) form an image correction factor based on the drop size symbol.

12. The method of claim 11, including the subsequent steps of:

(c) provide an image information; and

(d) form a modified image information based on the image correction factor and the image information.

13. The method of claim 12, including the subsequent steps of:

(e) form a marking fluid information based on the modified image information; and

(f) form an image based on the marking fluid information.

14. The method of claim 11, the marking fluid ejector including a storage means, the drop size symbol being disposed in the storage means, the drop size symbol determining step (a) including a step of accessing the storage means.

15. The method of claim 11, the marking fluid ejector comprising a radio frequency tag with the drop size symbol disposed therein, the drop size symbol determining step (a) including a step of detecting at least one radio frequency communication.

16. The method of claim 11, the marking fluid ejector comprising a housing exterior with a drop size symbol being disposed thereon, the drop size symbol determining step (a) including a step of detecting the at least one symbol.

17. The method of claim 16 the drop size symbol being machine-detectable.

18. The method of claim 16 the drop size symbol forming part of a marking fluid ejector identification code or serial number.

19. The method of claim 13, the image information including at least one of a red, green and blue image information.

20. The method of claim 19 the marking fluid information including at least one of a cyan, magenta, yellow and black colorant information.
