Understanding the ET-8550 Printhead Damper Brackets and Screws

Welcome to our detailed guide on handling the ET-8550 printer's printhead brackets and screws. This component is a crucial part of the printer, and understanding its installation can be somewhat challenging. Thankfully, our video tutorial, available below, offers a step-by-step visual guide to make this process smoother.

Step 1: Removing the Carriage Cover

The first step in managing the ET-8550 printer involves removing the carriage cover. This process includes unscrewing a couple of screws and carefully removing the spring. It’s essential to move the blue handlebar towards you, which eases the spring’s release. Remember, the proper handling of these components is vital to avoid damage to the printer.

Step 2: Taking Off the Waste Tank Cover

Next, focus on the waste tank cover located near the LCD panel. Gently push it to the left to remove it. This step is crucial before lifting the dampers to prevent ink spills. Using a suction tool can help draw back any ink present in the nozzle, ensuring a clean working environment.

Step 3: Detaching the Ink Tubes

The third step involves detaching the ink tubes from the dampers. This action is necessary to access the screws located underneath. Carefully unhook the tubes and move them out of the way. Ensure you keep track of the tubing connections to reattach them correctly later.

Step 4: Installing the Brackets and Understanding the Damper

Installing the brackets requires a good understanding of the damper’s orientation. The top part of the damper, which connects to the tubes, should face the back of the carriage. The hole in the bracket, where the screw goes, should be at the front. Testing the bracket's fit is crucial – a proper fit is indicated by a snapping sound or when the bracket can no longer be pushed further.

Step 5: Installing the Dampers

Installing the dampers might seem tricky at first, but with practice, it becomes more manageable. Approach this task with the damper angled towards the back. Ensure the tail of the damper is fully extended outward. Once aligned correctly, the damper should fit snugly into place, forming an 'L' shape.

Step 6: Installing the Screws

After the dampers are in place, it’s time to install the screws. This step might require a bit of finesse as the screws are not magnetic. Using a small screwdriver to align the screws before fully securing them with a drill can be helpful. Make sure each screw is properly positioned to avoid any loose components.

Final Steps: Reinstalling Dampers and Tubes

The final step is to reverse the disassembly process. Start by reconnecting all six dampers to their respective tubes, ensuring they are in the correct order to avoid mixing up inks. After ensuring all tubes are securely in place, reinstall the protective plastic guard and the carriage cover. Lastly, don’t forget to replace the waste tank before powering up the printer to test if everything works smoothly.
