How to Fix a Broken Screw Hole on an Epson ET 8550 DTF Printer

Question:

I have an Epson ET 8550 printer that I converted to a DTF printer. My washer gaskets for the ink dampener went out, so I ordered a replacement. While reinstalling the dampeners, I accidentally broke one of the screw holes that secure the dampener in place. I was wondering if there is a print head case replacement or if I have to buy a whole new printer. Look at the picture for reference. My finger is pointing to the damaged screw hole.

Thank you for reaching out to us at BCH Technologies. We are grateful for your engagement and support, particularly with regard to our YouTube channel BCH Technologies on YouTube. Your feedback plays a crucial role in further developing our technical expertise.

Firstly, it is essential to address an issue visible in the picture you provided. Your printhead's FFC (Flexible Flat Cable) is not pushed all the way in and is installed at an angle. If you power the printer on in this condition, it could potentially burn out both the printhead and the mainboard. Ensuring that the cable is properly seated and secured is crucial. You may want to consider using a cover like the one available here: Printhead Protector Cover Guard for ET-8500 Series (https://bchtechnologies.com/printhead-protector-cover-guard-for-et-8500-series-et8500-et8550-l8160-l8180-ep-707a-fa09000/).

Regarding the broken screw hole, here are two effective methods to fix it:

1. Epoxy Method:
   • Apply a drop of two-part epoxy to the damaged area. You can find epoxy at Home Depot or any hardware store.
   • Once the epoxy is set, sand it down to create a smooth surface.
   • Drill a new screw hole into the epoxy. This method is durable and provides a long-lasting fix.
2. Super Glue and Baking Soda Method:
   • Sprinkle some baking soda onto the damaged area.
   • Add a few drops of super glue over the baking soda. The glue will set almost instantly, creating a solid base.
   • This method is quicker than using epoxy but might not be as durable in the long term.

Both methods will work for your situation. Choose the one that best suits your needs and the materials you have on hand.

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 (BCH Technologies Printer Repair Service). 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 (https://youtube.com/@bchtechnologies). 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 again for your question. We hope this helps you get your Epson ET 8550 back in working order!
