Resolving Epson ET-8550 Error Code 031002 and WiFi Connectivity Issues

Question:
I've installed a new motherboard purchased from you for my Epson ET-8550 printer, but it won't connect to WiFi. Additionally, I'm encountering error code 031002, indicating a printhead issue. Can you please assist?

Answer:

The error code 031002 is a printhead error, indicating a short circuit. When a printhead is defective or short-circuits, it can severely impact other printer components, most notably the motherboard. If your original mainboard was damaged due to this issue and was replaced without simultaneously replacing the problematic printhead, the short circuit could also damage the new mainboard.

Here's a detailed breakdown of this situation:

• Error 031002: This is typically caused by a shorted printhead. The printhead, electrically connected directly to the mainboard via flexible flat cables (FFC), can transfer electrical faults back to the mainboard, potentially causing severe damage.

• WiFi Connectivity Issues: A compromised mainboard or incorrect installation can impact peripheral functions like WiFi connectivity. First, ensure that the mainboard and all connections are correctly and securely seated. Double-check all cable connections and verify that no pins are bent or damaged.

The good news is that your mainboard might still be salvageable if the printhead’s issue wasn't severe enough to cause irreversible damage. Every mainboard we ship is rigorously tested before leaving our facility. Therefore, if the problem persists, replacing the faulty printhead and thoroughly checking your cables (FFC) for any visible damage or signs of a short would be a prudent step.
