Troubleshooting Power-On and Cartridge Recognition Issues on Epson WF-7710 Printers

Question: I have two Epson WF-7710 printers that are experiencing issues. Printer #1 won't power on or display anything, despite having a functioning power supply. Printer #2 doesn't recognize the installed cartridges and now says none of the cartridges are recognized after initially printing fine. How can I fix these problems?

Thank you for contacting us at BCH Technologies. We appreciate your engagement and support, particularly with our YouTube channel (BCH Technologies). Your feedback plays a crucial role in further developing our technical expertise. Let's address the issues you're facing with your Epson WF-7710 printers.

Printer #1: Power-On Issues For Printer #1 (serial X45T069229), the issue seems to be with the mainboard, the printhead FFC (Flexible Flat Cable), and potentially the printhead itself. Here’s a detailed troubleshooting approach:

  1. Check the Mainboard: The mainboard is the most likely culprit. To diagnose it, you need to remove the mainboard and test the fuses. This requires infrared equipment to trace the power flow, which can be quite extensive. If you’re not equipped for this, consider sending the mainboard to a professional service like ours for diagnosis and repair.
  2. Inspect the Printhead FFC: The FFC connecting the printhead to the mainboard might be damaged or loose. Carefully inspect it for any signs of wear or disconnection.
  3. Evaluate the LCD Display Panel: Although rare, issues with the LCD display panel or its FFC could cause power-on problems. Ensure all connections are secure and check for any visible damage.

Printer #2: Cartridge Recognition Issues For Printer #2 (serial X45T056304), the problem is related to the printer not recognizing the cartridges. Here’s how to address this:

  1. Replace with Full Cartridges: The Epson WF-7710 may display an error message if a cartridge is less than half full, even if it allows printing initially. To avoid this, search for "refillable cartridge for printer WF-7710" and purchase them from a reliable source such as eBay. Using full cartridges should resolve the recognition issue.
  2. Reset the Printer: Sometimes, resetting the printer can help it recognize the cartridges. Unplug the power cord, wait a few minutes, and plug it back in. Ensure the cartridges are properly seated.
  3. Update Firmware: Ensure that the printer’s firmware is up to date. An outdated firmware can cause compatibility issues with cartridges.
  4. Clean the Cartridge Contacts: Gently clean the gold contacts on the cartridges and inside the printer where the cartridges sit. Use a lint-free cloth and a bit of rubbing alcohol to remove any dirt or residue.

Generic Paragraph: Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility. Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you once again for reaching out. We appreciate your support and are here to help with any further issues you may encounter.
