1. Inspect each empty laser toner cartridge for damage. Undamaged cartridges and parts are used in manufacturing.

2. Before the cartridge can be used in production, Quality Assurance makes a quality inspection of the cartridge parts. All critical compo- nents, like the toner, are 100% print tested and remaining compo- nents are inspected.

3. Disassemble and inspect each cartridge. The shell is inspected and cleaned. All OEM or other manufacturer’s labels are removed. All parts are replaced if there is any sign of damage.

4. Disassemble, clean and inspect the toner waste hopper.

5. Inspect and clean the primary charge roller. Refurbish if applicable.

6. Disassemble, inspect and clean the toner hopper. All OEM and other manufacturer’s labels are removed.

7. Prepare the toner hopper for the sealing process. The toner hop- per is split, if applicable, the sections are then inspected and the surface is prepared for the sealing process.

8. Developing roller (mag roller) preparation. Clean and inspect the developing roller assembly. Refurbish, if applicable.

9. Prepare the gears, bushing, corona wires, etc. The small parts are inspected and cleaned ultrasonically, if applicable.

10. Replace the wiper blades. Clean and inspect the doctor blades.

11. Seal the toner hopper. The appropriate seal is applied, either heat activated adhesive or pressure adhesive. Foam strips are then ap- plied and an air pressure test follows, if applicable. If the seal fails to hold air, it is rejected.

12. Fill toner hopper with premium, graphics toner. Weigh each toner hopper 100% to verify fill amount. Install toner hopper cap. Shake hopper, reject if any toner is leaking.

13. Assemble toner hopper. Install prequalified developing roller. Test for proper electrical performance, if applicable. Install prequalified or new doctor blade. Complete final assembly with prequalified parts.

14. Assemble the waste hopper. A new aftermarket wiper blade is in- stalled per design, assembly is completed with prequalified parts, and a shutter protector is added if needed.

15. Install the premium drum (OPG). Powder and lubricant are added for reliable performance, and the drum is matched to the toner.

16. Begin the cartridge assembly process. The developing roller is primed with toner before the cartridge is assembled. The final step of assembly is taken, and the lot stickers are attached to the car- tridges.

17. After assembly, begin cartridge print testing, each cartridge is print tested for performance. If any print defects are detected the car- tridge is rejected (non-destructive test).

18. Begin quality assurance in-process testing. Random cartridges are tested (including destructive testing) by quality assurance; if any car- tridge fails, the entire lot is placed on hold and reinspected.

19. Inspect and clean the cartridge for the last time; place cartridge in sealed bag if applicable.

20. Place cartridge securely in the approved packaging insert and into the appropriate proprietary shipping carton; both provide maxi- mum protection to the cartridge during shipping and handling. An instruction sheet is also included with installation and cleaning information. A date code is applied to the carton to use for any necessary tracking.
