What Tools and Glue Are Used for Extreme Epson Printhead Deep Cleaning and Resealing?

Question

I run a printer repair service in Brazil, and I watched your video about extreme bone-dry printhead cleaning for recovering Epson printheads that many people would normally give up on. What are the names of the tools used in the video, and what brand of glue do you use to reattach or reseal the printhead after opening it? In our shop, we usually do not open the printhead to unclog it, so sometimes we end up replacing the printhead because of severe clogs.

Answer

For the tools used in the video, the complete tool kit is our Printhead Deep Cleaning & Reseal Kit, which you can find here: FA040XX Printhead Deep Cleaning Reseal Kit [https://bchtechnologies.com/products/fa040xx-printhead-deep-cleaning-reseal-kit].

This type of kit is designed for extreme printhead recovery work, especially for Epson printheads that are severely dried, clogged, or considered beyond normal cleaning. It is not the same as a basic syringe flush or surface cleaning. The process shown in the video involves opening the printhead, cleaning internal ink passages, and then resealing the head carefully so it can hold pressure and prevent leaks.

For the glue, there is no special secret brand required. The adhesive used is simply epoxy. You can replace it with almost any good-quality quick-set epoxy or, in some cases, super glue. However, epoxy is generally preferred because it fills small gaps better, cures stronger, and gives a more reliable seal when rejoining parts of the printhead housing. Super glue can work in some situations, but it is thinner, more brittle, and less forgiving if the surfaces are uneven or if there are small gaps.

When choosing an adhesive, the most important points are not necessarily the brand, but the properties of the glue. You want something that bonds well to plastic, cures hard, resists moisture, and does not dissolve easily when exposed to ink or cleaning solution. A quick-set two-part epoxy is usually a practical choice because it gives you enough working time to align the printhead parts, but it does not take too long to cure.

That said, opening a printhead is a last-resort procedure. Most Epson printheads are not designed to be opened and serviced internally. Once the head is opened, there is always a risk of damaging the internal membrane, filter screen, nozzle plate, manifold, or channel structure. Even if the clog is removed, the printhead may not perform correctly if the internal seal is not restored evenly. A small air leak, uneven glue line, or blocked channel can cause missing colors, cross-contamination, weak suction, ink starvation, or leaking.

In regular repair work, I would usually try less invasive methods first. These may include soaking the printhead, using proper printhead cleaning solution, flushing through the ink ports with controlled pressure, cleaning the capping station, checking the pump, inspecting dampers or cartridges, and verifying that the ink system is delivering ink correctly. Sometimes what looks like a clogged printhead is actually caused by an air leak, bad damper, blocked cartridge vent, weak pump, clogged cap top, or dried ink around the docking station.

The extreme method in the video is mainly for cases where the printhead is already considered unusable or where the alternative is replacement. In that situation, opening and resealing the head becomes more reasonable because there is not much left to lose. It can be a useful technique for professional repair shops, but it requires patience, careful alignment, and an understanding that not every head can be recovered.

If you are doing this in a repair shop, I would recommend practicing first on printheads that you already consider scrap. That way, you can learn how the head separates, how much adhesive to apply, where not to apply glue, and how the internal channels are arranged. Too much glue can squeeze into the ink path and permanently block the head. Too little glue can cause leaks or pressure loss. The goal is to reseal the opened area without allowing adhesive to enter the ink channels, nozzle area, or internal filter path.

Also, after resealing the printhead, it is important to let the adhesive cure fully before reinstalling the head or applying cleaning fluid pressure. Even quick-set epoxy may harden quickly on the surface but still need additional time to reach full strength. If the head is tested too soon, pressure from flushing or ink flow may break the seal and cause leakage.

So, to answer your question directly: the tool set is the FA040XX Printhead Deep Cleaning Reseal Kit from BCH Technologies, and the glue is a standard epoxy. You can use any suitable quick-set epoxy available locally in Brazil, and in some lighter cases, super glue may also work. However, for a stronger and more reliable reseal, I would lean toward epoxy rather than super glue.

Addressing printer issues can be a complicated affair because many of these problems require hands-on inspection and testing. For that reason, we are not able to provide remote troubleshooting, suggestions, or support for printer repairs. We do offer an in-person evaluation and repair service through our local diagnostic facility: BCH Technologies Printer Repair Service [https://bchtechnologies.com/printer-repair-service]. Because demand is high, we operate on a first-come, first-served basis, so it may take a few weeks before you can bring or send in your printer for drop-off. Our services are structured to repair either the whole printer or specific parts, and the instructions are provided clearly on the repair service page. However, we understand that our rates may not be the most economical option for everyone. For that reason, we strongly recommend self-help through online research whenever possible. You can start with YouTube or visit our YouTube homepage at BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]. Use the search icon next to "About" on the right-hand side of the menu bar to search for specific topics. I receive dozens of questions every day asking where to find videos on certain repairs, and after creating videos for more than nine years, it is difficult to remember every single one. Using YouTube's search function is usually the fastest method, and YouTube may also recommend helpful videos from other creators.

Thank you again for reaching out and for watching our video. I appreciate your work as a printer repair technician, and I'm glad the video was useful for your repair process.
