Abstract

An apparatus, a system and a method are provided for testing a cartridge. The apparatus and/or the system is attached and/or is connected to the printer containing the cartridge via a port of the printer. The apparatus and/or the system communicates with and/or controls the printer. The apparatus and/or the system transmits a signal to the printer. The printer prints one or more pages of paper to test a quality, an effectiveness, a longevity and/or a durability of the toner cartridge. A user inspects and/or reviews one or more pages of paper printed by the cartridge to determine the quality, the effectiveness, the longevity and/or the durability of the toner cartridge.

Claims

1. An apparatus for testing a cartridge in a printer for a defect wherein the printer has a port wherein the defect of the cartridge is identified by a yield test and a post test, the apparatus comprising:

a housing having walls defining an interior wherein the housing has an exterior surface;

a logical device within the interior of the housing wherein a power source supplies a voltage to the logical device wherein the logical device is programmed to instruct the printer to perform the yield test and the pulse test;

a user interface located on the exterior surface of the housing wherein the user interface is connected to the logical device wherein the yield test or the post test is selected with the user interface and further wherein the logical device is programmed to produce a signal corresponding to the yield test and the post test; and

a connector on the exterior surface of the housing wherein the connector connects to the logical device wherein the logical device communicates with the printer via the connector and the port of the printer wherein the signal is transmitted from the logical device to the printer via the connector and the port of the printer and further wherein the cartridge prints a page of paper based on the signal from the logical device.

2. The apparatus of claim 1 wherein the power source is a battery located within the interior of the housing or an AC adapter.

3. The apparatus of claim 1 wherein the connector is a cable configured to be insertable into the port of the printer.

4. The apparatus of claim 1 further wherein the connector emits infrared light.

5. The apparatus of claim 1 further comprising:

a controller on the exterior surface of the housing to connect the power source and the logical device.

6. The apparatus of claim 1 further comprising:

a light emitting diode on the exterior surface of the housing.

7. The apparatus of claim 1 wherein the user interface has at least one button corresponding to the yield test and the post test.

8. A system for testing a cartridge in a printer for a defect wherein the printer has a port wherein the printer performs a test to identify the defect of the cartridge wherein a page of paper is printed by the cartridge based on the tests, the system comprising:

a housing having walls defining an interior wherein the housing has an exterior surface;

a logical device within the interior of the housing wherein the logical device is programmed to instruct the printer to perform the tests;

a battery within the interior of the housing wherein the battery provides a voltage to the logical device;

a user interface on the exterior surface of the housing wherein the user interface is connected to the logical device wherein one of the tests is selected with the user interface and further wherein a signal corresponding to one of the tests is produced by the logical device; and

a connector on the exterior surface of the housing wherein the connector is connected to the logical device wherein the signal from the logical device is transmitted to the printer via the connector and the port of the printer and further wherein the printer executes one of the tests based on the signal.

9. The system of claim 8 wherein the tests are a yield test and a post test.

10. The system of claim 8 further comprising:

a controller connecting the battery to the logical device.

11. The system of claim 8 further comprising:

a light emitting diode located on the exterior surface of the housing wherein the light emitting diode is controlled by the logical device.

12. The system of claim 8 wherein the connector emits infrared light.

13. The system of claim 8 wherein the connector is configured to be insertable into the port of the printer.

14. The system of claim 8 wherein the battery is rechargeable or replaceable.

15. A method for testing a cartridge in a printer for a defect wherein the printer has a port wherein the defect of the cartridge is identified by a post test or a yield test, the method comprising the steps of:

providing a housing having walls defining an interior wherein the housing has an exterior surface wherein a logical device is located within the interior of the housing wherein a user interface is located on the exterior surface of the housing wherein the user interface is connected to the logical device;

providing a voltage to the logical device wherein the voltage is continuous and uninterrupted;

programming the logical device to instruct the printer to execute the post test and the yield test; and

transmitting a signal from the logical device to the printer via the port of the printer wherein the signal corresponds to the post test or the yield test and further wherein the signal instructs the printer to execute the post test or the yield test.

16. The method of claim 15 further comprising the step of:

selecting the post test or the yield test with the user interface.

17. The method of claim 15 further comprising the step of:

controlling the voltage to the logical device.

18. The method of claim 15 further comprising the step of:

printing a page of paper based on the signal from the logical device.

19. The method of claim 15 further comprising the step of:

identifying the defect of the cartridge.

20. The method of claim 15 further comprising the step of:

testing the cartridge with the yield test and the post test.
