2. The Cartridge Network An Overview of the Cartridge Ink and Toner Business Presents:

3. Who is The Cartridge Network? The Cartridge Network Inc., is a California Corporation that specializes in offering Business Opportunities to individuals that want to start their own business, without the cost and expense of owning a franchise! We have chosen to work in the Cartridge Business because it has a tremendous annual growth and the consumable nature of the product, provides our network members with a huge “RESIDUAL INCOME” potential! Like toothpaste or shampoo, business and individuals need constant printer ink and toner replacement, so why not make a great living supplying those needs?

17. Machine refilling in Standard Atmosphere Air in the ink channels when no vacuum is applied. Note the air bubble in the picture below. Transparent acrylic cover

18. Machine refilling in Standard Atmosphere This cartridge has been filled with water to easily see the trapped air bubble when filling in Standard Atmosphere. Ink (water) is not in the ink reservoir when filling in standard atmosphere, which then requires vacuum priming

19. Machine refilling in Standard Atmosphere After filling in standard atmosphere, you have to apply external vacuum to the nozzle to pull ink into the print head. This process pulls air into the nozzle reservoir, which ultimately leads to print streaking and failure of ink to flow to the nozzle.

21. Machine refilling in a Vacuum -160 mm Hg (vacuum level 21%) Ink level -260 mm Hg (vacuum level 34%) Ink level

22. Machine refilling in a Vacuum -360 mm Hg (vacuum level 47%) Ink level -460 mm Hg (vacuum level 61%) Ink level

23. Machine refilling in a Vacuum -560 mm Hg (vacuum level 74%) Ink level -610 mm Hg (vacuum level 80%) Ink level

24. Machine refilling in a Vacuum -660 mm Hg (vacuum level 87%) This cartridge can barely work since the air bubble is not big enough to block the ink flow. -710 mm Hg (vacuum level 93%) Ink level

25. Machine refilling in a Vacuum -740 mm Hg (vacuum level 96%) This cartridge will print the full ink load because the size of the bubble is only 4% of the volume of the ink entrance area. If this cartridge was filled at an elevation of sea level and is now used at an elevation 6,000 feet, the size of the bubble would increase 24% in size, making it unlikely to work properly or have a shortened life cycle. Thus, you should induce a 97% internal vacuum level and fill at the approximate atmospheric pressure you will use the cartridge at.
