I’m a long time happy customer starting with the Epson R3000. I upgraded my printer to the R3880 and bought a whole new set of inks and cartridges. Because the 3880 needs the original chip and the printer came fully equipped, it took a long time of printing before I needed to replace the originals.
When I first attempted to do the chip transplant, the printer did not like the results, I thought I may have damaged one of the chips when removing, so I bought a used set of cartridges off the eBay . . and then printed with those for some time.
Now a year and a half later, I have attempted to replace all the inks, but I have four cartridges that cause the printer to error out. I have followed all the forum tips (confirming the proper installation . . . note that I got most of them working). And when I put in older non-InkJet Mall cartridges in those slots, then the printer works.
QUESTION: Could it be the InkJet Mall chips that need replacing? If so should I just order the PK, C, LLK, and LK? This seems to be the last of the troubleshooting steps.
