I am resubmitting my support request of May 11 entitled “Magenta Cartridge Impasse” here, thinking that perhaps I posted it in the wrong section. I also believe I have discovered a clue which may point to the solution.
Here are the facts:
I am undergoing an initial K7 set up on a 3880. The 3880 is in perfect working order and still functions with OEM cartridges.
The refillable Magenta cartridge is not being accepted by the printer, it shows the “ink cartridge error replace cartridge” message.
The OEM magenta cartridge with exactly the same Epson chip is being accepted by the printer. I have tried changing the OEM magenta chip with another one and the result was “a maintenance cartridge error”
Replacing the reset chip for the VM cartridge had no effect on this situation. Either I was so unlucky as to have received 2 defective VM reset chips or the reset chip is not the problem.
Elevating the cartridge did not solve the problem.
Here is the new clue:
I was able to create this exact situation with my other K7 printer, a 3800. In a desperate attempt to figure this out I returned to switching all exchangeable parts from the cartridges of the two K7 sets to try and isolate the source of the problem. At one point I placed the second OEM magenta Epson chip into the 3800 magenta cartridge and received the “maintenance cartridge error replace maintenance cartridge” message as I had on the other printer. I removed this OEM chip, marked it defective, and replaced it with the OEM chip that had been functioning properly in that printer up to that moment. It no longer functioned. I now began receiving the “ink cartridge error replace cartridge” message, just as I have been on the 3880, and, also exactly as is the case with the 3880, the OEM magenta cartridge still functions in the 3800.
I am no longer absolutely sure that this second OEM magenta chip is a magenta chip; obviously there is some kind of problem with it. If it is not would the printer react this way to an incorrect or defective OEM chip? If I have triggered some kind of Epson Anti-third party ink protocol can this be reset somehow?
I don’t believe that the reset chips have been compromised since the new reset chips were never in contact with the defective or erroneous OEM chip, yet still did not function in refillable cartridge.
Although I am encouraged by this clue it is also true that I now have two Epson printers with Jon Cone K7 ink sets that don’t work!
