Hello all, I have an Encad Novajet Pro 600e. I know it's an old machine but the shop that I am working for just can't replace it right now. I am having some problems with getting one of the cartridges to fire properly. We received this machine from a neighbor of ours and he had been using replacement cartridges (the kind without the computer chip) and he had taped a chip to the contact behind the cartridge in order to "fool" the machine into thinking that the cartridge had a chip. I know that this sounds totally rigged up, but it was working fine. Well, the machine sat dormant for a couple of weeks and now my magenta will not fire. I cleaned the jet plate and I have established good flow from the plate. I have tried uninstalling and then re-installing this damn cartridge 10 times. Nothing. Then I ran it through some of the tests programmed into the menu. Nothing. I ran it through the "prime" function and I noticed something interesting. After it "primes" all of the colors, it prints this line of text: "COMPENSATION AVAILABLE IN THE ABOVE # OF PASSES." And then under that line of text, it reads: YELLOW (1,2,4,6,8,10) MAGENTA (-,-,-,-,-,-,-) CYAN (1,2,4,6,8,10) BLACK (1,2,4,6,8,10). Does anyone have a suggestion for me? I'm banging my head on the wall with this one. I know that you can purchase a chip that you install to the machine's board that bypasses the need for the cartridge chip but my boss HATES spending money and even if I did order the part, I would have to wait 3 weeks for it to ship from China. Any help would be appreciated.
