L1800 PF Roller Shoes Upper Paper Guide Assembly Installation

This guide will walk you through the installation of the upper paper guide (UPG) assembly for the Epson L1800 PF roller shoes. This process might seem intricate, but with clear steps and attention to detail, you can perform this task efficiently. Additionally, BCH Technologies offers a helpful video below to visually guide you through the process.

Remove the Black Guide Plate

Begin by locating the black guide plate at the back of your printer. This plate is usually secured by three screws, which you'll need to remove. While Epson recommends removing the entire back side, an angled screwdriver can help you avoid this extra step. By using an angled screwdriver, you can reach and unscrew these screws without dismantling the entire back panel.

To remove the plate, understand that it is secured by three tabs. The top tab is designed for sliding down to secure the plate, while the bottom tab needs to be pushed in to release the plate. This process requires pushing in each tab and lifting the plate simultaneously.

Remove the Guide Rod

Next, you'll encounter long springs and, in some models, an additional rod. This rod might not be present in all models, but if it is, removing it is straightforward. You can push the rod down and slide it out of its position. If the rod is secured by a screw, you may need to unscrew it. Typically, you don't need to remove the rod completely—just sliding it out of the way is sufficient for most tasks.

When reinstalling, push the plate down first and then slide the rod back into place. This step ensures that the rod is correctly aligned and secured without disrupting other components.

Remove the UPG Torsion Spring

The next step involves removing the UPG torsion spring. This component, known as the upper paper guide torsion spring, needs to be handled carefully. You should grasp the shoe on both sides, lift it up, and then slide it out.

Understanding the assembly of the UPG is crucial for this process. The UPG assembly sits on top of the paper feed rod, which holds and pushes the paper down, allowing it to feed correctly when the rod spins. Familiarize yourself with the two tabs, referred to as shafts, which play a critical role during reinstallation.

Understand How the UPG Assembly Works

The UPG assembly comprises a triangular assembly with two wheels, pushed down by a large spring. Often, during cleaning, the front side of the UPG might be missing, which can complicate the installation. Ensure that the triangular assembly is correctly oriented, with the triangle pointing upwards. Hook the assembly onto the shaft properly, ensuring that both the front and back components are in place.

Install the UPG Assembly

To install the UPG assembly, carefully observe the location of the two shafts. Imagine a large cross where the shaft comes in from the top side and slides down to sit in a ditch. This visualization helps in positioning the UPG assembly accurately. Lift the assembly, slide it into the correct position, and ensure it falls into place securely.

Once the shafts are correctly positioned, focus on aligning the holes. This step is critical for the functionality of the assembly, as Epson designs rely heavily on precise alignment of these components.

Install the Torsion Spring

The final step involves installing the torsion spring. Hold the spring correctly and use the front spring to poke into the designated hole. It's advisable not to remove every component at once; this helps in remembering the original positions and makes reassembly easier. Rest the spring in its slot, check the alignment, and ensure it slides into the hole perfectly.

By following these detailed steps, you can efficiently install the upper paper guide assembly in your Epson L1800 PF roller shoes. Proper maintenance and careful reassembly will ensure your printer continues to function smoothly.
