Epson 4900 Cone Color Inks




This morning all six (left side) cartridges appeared blank. Previously two would need to be ejected and then returned to get the printer to recognize them. I have tried all kinds of off/on and other combinations of the printer. Wells says that if one chip is bad, it can take out the whole bank of inks. Is there a way to determine where the problem is, and then a way to fix it. I bought these inks and cartridges at least two years ago. Perhaps they have batteries. Thanks for your assistance.

Hi John~

Based on your order history, I suspect you’re dealing with dead chip batteries. You can either replace the chip batteries, or get new non-battery style chips.
Battery replacement information is available here:
You can get new batteries or Non-battery chips here:

I hope this helps. Please let me know if yuo have further questions or there’s anything else I can help you with.
Warmly~ Dana
