How to Fix a Printhead for L1800: Tips and Pointers

In this article, we'll discuss how to fix a printhead for the L 1800. While this is not a comprehensive review or tutorial on how to fix the printhead, we hope to provide some helpful tips and pointers to assist you in repairing your printhead.

To begin, take a paper towel and clean around the printhead. Sometimes, there may be dried ink around the printhead that needs to be removed. If this is the case, you may need to remove a piece that is covered by an FFC protective cover. This cover may have saved the printhead from being burned up, and we will provide a link to show you how to install it.

Next, remove the screws and crack open the printhead like an oyster or clam. Don't worry about breaking anything as the seals are just glue seals and don't need a seal at all. You will see two white ink spots on the bottom, and if the ink is still wet and not powdery, you can be optimistic about fixing the printhead.

To fix the printhead, you will need to suck out old ink and push some cleaning solution in. It's important to note that this process should not be done at home, and we're only showing it for reference. To do this, you will need a needle that can go into the ink intake. The intake is 0.6 millimeters, and regular needles are almost twice the size of the ink intake, so you will need a thinner needle. You can find the needle at bchtechnologies.com, where you can select the gauge or convert it to millimeters.

The goal is to suck the old ink out of the ink intake for the particular printhead, dissolve any clogs inside, and use cleaning solutions from BCH. The cleaning solution from BCH is blue and doesn't dissolve the clog but makes it soft so you can work on it. It has a special chemical in it that's blue, and you may find other sellers that dye their cleaning solutions into blue to mimic this. Inject a little bit of cleaning solution, leave it for 20 minutes, and come back to scrape it out.

Use a needle to stir and soften the clog, leave it for another 20 minutes, and use a tiny drill from the same page to work on the wall of the ink intake. Circle the drill, add more cleaning solution, and scrape until you think there's no clog. Then, use an ultrasonic cleaner or brush to clean it. Clean the black rubber pad and use a syringe in the Clean Solution kit to push and clean those channels. Repeat the process as necessary.

When both parts are clean, put them back together and push cleaning solutions through the white ink channel. You can now use the productive cover for the FFC, which will prevent the ink from dripping down and frying the main board. This cover is a lifesaver, and we will provide a link to purchase it. Add a little bit of silicon seal to seal the edge of the cover, and you're all set.

While this is how we work on the printhead, you may have your own tips. Feel free to share them in the comments section, and we hope this article has been helpful to you. Visit us at www.bchtechnology.com or locally at Greensboro, North Carolina. Cheers!
