Tackling Epson Error Code 0x69: A Comprehensive Guide

Navigating the world of printer errors can be intimidating, especially when you come across cryptic error codes like 0x69 on your Epson WF-3640 printer. Fear not, the experts from BCH Technologies have a hands-on solution to help you tackle this head-on. Let's embark on this journey to fix the error and make your printer operational again. Don't forget, there's a detailed video at the end of this blog post for a visual guide.

Section 1: Disassembling the Printer

The first step to tackling the 0x69 error is to gain access to the printer's interior. To do this, start by removing the backside cover. Remove the screws holding the cover in place, disconnect the wires connecting to the main board, and remove the FFC cable that connects to the main ward. This process involves disconnecting the scanner on top, which you can do by lifting it and pushing in the tab on the right side.

Section 2: Removing the Top Cover

Next up, you need to remove the top cover of your printer. Remove the hinge that holds the top cover, along with all other screws. Make sure to remove the screw under the hinge at the back. Once you have that off, the interior of your printer will be exposed, ready for the next steps.

Section 3: Checking and Fixing the Encoder Strip

Now, direct your attention to the encoder strip. If it's off, this could be the source of your error code 0x69. Detach the encoder strip, place it back in its place, ensuring that it goes through the sensor on the back of the carriage. Then, on a metal piece, you'll see a small hook where you need to latch the encoder strip. Test the carriage afterwards to ensure smooth movement.

Section 4: Adjusting the Waste Ink Capping Station

In the quest to fix the 0x69 error, it's important not to overlook the waste ink capping station. You might encounter a notch that's not going all the way over. If that's the case, you'll need to replace the waste tank. Once done, ensure the new waste tank aligns with all the gears before you put the metal piece that holds the encoder strip back on.

Section 5: Reassembling and Testing

Once you have addressed the potential issues causing the 0x69 error, it's time to reassemble your printer. Replace all the screws and the top cover, making sure everything fits snugly in place. Connect the FFC cable, all other connections, and the ground wire. Now, it's time for the moment of truth - switch on your printer and check if the error persists.

Section 6: Ensuring Successful Resolution

If you have followed the steps accurately, the 0x69 error should no longer appear. In case your printer asks for a maintenance box, make sure to put it in the back. Remember, a fully functional printer is a happy printer, so keep an eye out for any other potential errors and handle them as efficiently as you tackled this one.
