HP Designjet 750C Cartridge re-seat problems?

Every time I reseat the cartridges, I get the same problem. It is mainly the Yellow Ink cartridge. I have replaced the Carriage Assembly and the trailing cable but that did not solve anything. I have run out of possible solutions! Please help!! If you need additional details please ask.

-Thanks in advance!

Update:

So what happens is it seems like the printer or carriage assembly won't register that the ink cartridge is inserted. When I insert it, it prompts me by saying "Reseat Cartridge" (even though the cartridge IS seated properly). When I remove it, it says "Replace Cartridge". I have tried both new and used cartridges on it and it treats them the same. I have cleaned the contacts on both the carriage assembly and the cartridge so they can make the best possible connection. I hope this info helps. Please ask if you more specific details.

    What is the exact problem you're having? You mention re-seat problems, but I don't know what problem it is you're tring to fix by reseating.

    UPDATE:

    Wow. Seems like you've done everything possible. Replaced the carriage assy & cable, cleaned all the appropriate contacts, tried different cartridges.... so here are the possibilities:

    1) The cartridges you tried are also defective

    2) The new carriage is also bad, maybe a design flaw

    3) Make sure you're using the correct cartridges designed for your printer
