Supply and mixing cartridges
Certain examples relate to mixing and/or supply cartridges for printing apparatus. One example implementation includes a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus. A storage medium stores a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge; a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.
1. A printing material mixing cartridge comprising:
a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus; and
a storage medium storing:
a reservoir printing material level parameter indicative of the amount of printing material in the reservoir;
a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge, wherein a recirculation event experienced by the cartridge comprises receiving printing material from the printing apparatus into the reservoir and returning the printing material from the reservoir to the printing apparatus; and
a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.
2. The printing material mixing cartridge of claim 1 , wherein the reservoir printing material level parameter is rewritable by the printing apparatus, the maximum recirculation cycles parameter is read-only, and the recirculation cycle counter is not resettable and is a one directional counter updatable by the printing apparatus.
3. The printing material mixing cartridge of claim 1 , wherein the storage medium comprises a printing material color parameter indicative of a color of the printing material that may be received from the printing apparatus.
4. The printing material mixing cartridge of claim 1 , wherein the storage medium comprises a removal protection parameter indicative of whether the printing material mixing cartridge is removable from the printing apparatus.
5. The printing material mixing cartridge of claim 1 , wherein the storage medium comprises a mixing cartridge identifier and a paired supply cartridge identifier.
6. The printing material mixing cartridge of claim 1 , wherein the storage medium comprises process instructions for controlling a recirculation process in the printing apparatus.
7. The printing material mixing cartridge of claim 6 , wherein the process instructions correspond to a characteristic of the printing material and/or the printing apparatus.
8. The printing material mixing cartridge of claim 6 , wherein the process instructions are stored in a compressed XML file.
9. A printing material supply cartridge comprising:
a reservoir for storing printing material to supply a printing apparatus; and
a storage medium storing:
a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; and
a printing material counter indicative of the total amount of printing material in the reservoir and the printing apparatus.
10. The printing material supply cartridge of claim 9 , wherein the reservoir printing material level parameter is rewritable by the printing apparatus, the printing material counter is not resettable and is a one directional counter updatable by the printing apparatus.
11. The printing material supply cartridge of claim 9 , wherein the printing apparatus comprises a removable printing material mixing cartridge containing part of the total amount of printing material.
12. The printing material supply cartridge of claim 9 , wherein the storage medium comprises a printing material characteristics parameter indicative of a characteristic of the printing material.
13. The printing material supply cartridge of claim 9 , wherein the storage medium comprises a removal protection parameter indicative of whether the printing material cartridge is removable from the printing apparatus.
14. The printing material supply cartridge of claim 9 , wherein the storage medium comprises recirculation process instructions for controlling the printing apparatus.
15. The printing material supply cartridge of claim 9 , wherein the storage medium comprises a supply cartridge identifier and a paired mixing cartridge identifier.
16. The printing material supply cartridge of claim 9 , wherein the storage medium comprises process instructions for controlling a recirculation process in the printing apparatus.
17. The printing material supply cartridge of claim 16 , wherein the process instructions correspond to a characteristic of the printing material and/or the printing apparatus.
18. The printing material supply cartridge of claim 16 , wherein the process instructions are stored in a compressed XML file.
19. The printing material supply cartridge of claim 9 , wherein the percentage of solid pigments by weight is 20 to 25% white ink and 10 to 15% other inks.
20. The printing material supply cartridge of claim 9 , wherein the D90 particle size distribution is 350-550 nm for white inks and 200-450 nm for other inks.
