Maintaining Your Printer: The Ultimate Guide to Unclogging the Epson L1800 and L805 Printhead

Keeping your printer in optimal condition is crucial for ensuring the best print quality and longevity of your device. One of the common challenges that printer owners face is dealing with clogged printheads. This issue can lead to poor print quality and even damage your printer if not addressed promptly. In this guide, we will explore how to unclog the Epson L1800 and L805 printheads using the TMS machine and unclogging adapter from BCH Technologies.

Our step-by-step process will help you tackle this issue effectively, ensuring your printer operates smoothly and efficiently. We also have a video below to show how it's done.

Introduction to the TMS Machine and Unclogging Adapter

The first step in unclogging your Epson L1800 or L805 printhead is understanding the tools required for the task. BCH Technologies provides a TMS machine and a printhead unclogging adapter specifically designed for this purpose. This equipment is vital for achieving the best results without causing further damage to your printhead.

The TMS machine works for several models, including the L1800, L805, 1390, IO1800, 1430, 1400, and 1410. Its versatility makes it a valuable tool for any printer owner dealing with clogs. The adapter matches the three holes on the printhead, allowing it to connect seamlessly. It's worth noting that additional holes within the larger ones are intended for deeper cleaning, but this guide will focus on a more introductory cleaning process.

Installing the Printhead on the Unclogging Adapter

Installing your printhead onto the unclogging adapter is straightforward. Begin by placing your printhead onto the adapter, ensuring that the holes align correctly. Next, insert the stainless steel bolts and secure them using thumb nuts. It's crucial to tighten the nuts with your fingers rather than using a wrench, as this prevents over-tightening and potential damage to the printhead.

Ensure that the nuts are adjusted sequentially to maintain an even fit, which helps prevent any misalignment. This step is essential for creating a stable setup that allows the TMS machine to function effectively during the cleaning process.

Connecting Tubes to the Unclogging Adapter

After securing the printhead, it's time to connect the tubes to the unclogging adapter. You'll find seven tubes in your package, six of which connect to the adapter's nipples. The TMS machine, sold separately, works by drawing liquid from the shorter tube and expelling it through the longer tube. It's crucial to avoid getting the electronic parts wet, so ensure the side with the FFC cable is facing upwards.

The shorter tube features a small connector, and you can connect it to the adapter, allowing the TMS machine to suck water from the adapter and then expel it. This setup helps create a circulation system that effectively cleans the printhead.

Operating the TMS Cleaning Process

Now that everything is set up, you can begin the cleaning process. Turn on the TMS machine and let it run for a few seconds. This initial operation clears any residual ink or particles beneath the printhead. As the water circulates, it will help dislodge any clogs within the ink channels.

During this process, you might notice ink rising in the unclogged channels. This phenomenon is due to a micro-turbulence effect created by the water flow. Unlike traditional push-pull methods, which can damage the printhead, the TMS machine utilizes a slow, spiral force to gently push particles up and out of the nozzles.

Interpreting the Unclogging Results

As the TMS machine runs, you will start to see results. Channels that are unclogged will show clear water flow, while others may need further attention. For instance, if you notice resistance or a vacuum effect when drawing ink, the channel is likely still clogged.

In such cases, using a 10 ml syringe included in the package can help. Gently draw a little ink from the problematic channel, which can encourage the unclogging process. It's important to be gentle and avoid applying excessive force, which can damage the printhead.

If a channel remains clogged despite your efforts, it may require additional cleaning or professional attention. The slow and steady approach recommended by BCH Technologies minimizes the risk of damage while effectively clearing blockages.

Unclogging the Printhead Manifold

Sometimes, clogs occur not just in the ink channels but also in the manifold. To address this, you'll need to remove the printhead from the adapter and unscrew the three screws holding the silver protective plate in place. Carefully separate the core from the manifold without damaging the rubber plate on the core.

Using a syringe and unclogging needles, check the manifold for clogs. If the syringe draws a vacuum, the channel is likely blocked. In such cases, employing an ultrasonic cleaner with a DTF concentrate solution and distilled water can help. The ultrasonic vibrations assist in breaking down stubborn clogs without damaging the printhead.

Remember to only use cleaning solutions on the manifold, not the core, as the latter is more sensitive and prone to damage from harsh chemicals. After ultrasonic cleaning, reassemble the manifold and reconnect the printhead to the adapter.

Cleaning the White Ink Channels

White ink channels often present unique challenges due to the density and composition of white ink. If you find these channels clogged, start by ensuring that the manifold is clear. Connect all tubes and run distilled water through the system, checking for clear flow in the white channels.

If necessary, give the system a gentle boost using the syringe. White ink channels may require a little more patience and attention, but with the right approach, they can be successfully unclogged without damage.

Installing the Unclogged Printhead

Once your printhead is clean and free of clogs, it's time to reinstall it into your printer. Before doing so, ensure that any residual ink in the system is drawn out to prevent contamination. Use a syringe to draw ink from the waste tube, checking for a smooth, buttery flow. If you encounter a vacuum, it may indicate a clogged capping station that needs servicing.

After addressing any issues with the capping station, install the printhead and perform a self-cleaning cycle. Observe the back of the printer to ensure ink is flowing correctly through the channels. You may also draw some air out of the waste tube to facilitate ink flow.

Once you've confirmed that the printhead is functioning correctly, test print a page to check the output. Ensure all colors are present and vibrant, indicating that the unclogging process was successful.

In conclusion, maintaining your printer with regular cleaning and unclogging can significantly extend its lifespan and improve print quality. The TMS machine and unclogging adapter from BCH Technologies offer an effective and gentle solution for addressing clogs in the Epson L1800 and L805 printheads. By following these steps and utilizing the right tools, you can keep your printer running smoothly and efficiently.
