Printer Repair Questions? Ask IT Technicians for Answers ASAP
Hi, I'm Sadique. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
Epson printers use a series of thin gold plated wire contacts that the cartridge chip slides and presses against - when cartridge is installed. These contacts can corrode, or stick to the chip, particularly if they ever had any ink contamination. The wires can sometimes bend, or even get pulled out - with cartridge, when it is removed. If this is the case, there may not be that much you can do to fix it, other than getting the printer serviced.Note: If you can find the missing wire contact and it's not damaged, sometimes it's possible to push it back in it's slot. It's fiddly and you need careful vision, but it can be done. Be careful not to bend it or damage something else in the process.
As your printer is under warranty, you can repair it free of cost.
