Imaging apparatus having a programmable throughput rate
View Patent ↗An imaging apparatus includes a print engine for printing on a print medium. A device is communicatively coupled with the print engine. The device is programmed to set a throughput rate for the print engine. A controller reads the device, and operates the print engine at the throughput rate designated by the device.
1. An imaging apparatus, comprising:
a print engine for printing on a print medium, said print engine having a defined initial throughput capability having a throughput rate;
a device communicatively coupled with said print engine, said device being programmed to upgrade said throughput capability to a new throughput rate for said print engine; and
a controller for reading said device, said controller operating said print engine at said throughput rate designated by said device, wherein said device includes a lookup table established in a memory, said lookup table containing a plurality of throughput entries, and a throughput pointer for selecting one of said plurality of throughput entries as said throughput rate for said print engine.
2. The imaging apparatus of claim 1 , wherein said throughput pointer has a value that is programmed to point to a particular entry of said plurality of throughput entries.
3. The imaging apparatus of claim 2 , wherein said value is assigned an initial value that points to a default entry of said first plurality of throughput entries.
4. The imaging apparatus of claim 1 , said imaging apparatus being communicatively coupled to a source for supplying a pointer value to said device for selecting said throughput rate.
5. The imaging apparatus of claim 4 , wherein said source is a memory associated with a supply item.
6. The imaging apparatus of claim 4 , wherein said source is a database.
7. The imaging apparatus of claim 4 , wherein said source is a replaceable hardware component.
8. The imaging apparatus of claim 4 , wherein said source is a memory of a printing cartridge.
9. The imaging apparatus of claim 8 , wherein said printing cartridge is one of an ink jet printhead cartridge and an electrophotographic (EP) cartridge.
10. The imaging apparatus of claim 1 , wherein a user upgrades said imaging apparatus by programming said device to effect said new throughput rate for said print engine.
11. The imaging apparatus of claim 1 , wherein said device is initially programmed with a default value.
12. The imaging apparatus of claim 11 , wherein said default value is overruled by a reprogramming of said device.
13. The imaging apparatus of claim 11 , wherein said default value triggers said controller to check for a hardware indication of said throughput rate.
