Troubleshooting and Cleaning L-1800, Artisan 1430, 1440, 1390 Printer's Capping Station - A Comprehensive Guide

In the world of printer maintenance, one critical aspect that often gets overlooked is the capping station. If you're a repair shop owner like me, you understand the frustration that comes with a clogged capping station. In this guide, we'll take you through the essential steps to troubleshoot and clean your printer's capping station. Whether you own an L1800 or a 1430, these methods apply. We've also included a video tutorial below to demonstrate the process.

Get the Right Tools

Before we dive into the troubleshooting and cleaning process, it's essential to have the right tools on hand. Head over to BCH Technologies and look for the "Little Spring for L1800 Waste Capping Station." Additionally, you'll need a syringe (either 50ml or 100ml) with a plastic refill adapter. These tools will help you effectively tackle capping station issues.

About the Capping Platform & Rubber Wiper

Begin your inspection by looking at the capping platform. It's crucial to ensure it can move freely without obstructions. The rubber seal on the platform should be clean and free of any ink residue. If you notice dried ink on the rubber wiper, use tweezers to gently remove it. A clean wiper ensures proper printhead cleaning.

About the Air Tube

The air tube, which runs to the right-hand side of the platform, is another critical component. Check the spring for the lever that controls the air hole; it should be in good condition. Ensure the air hole is open and clear. This is essential for maintaining proper airflow.

About the Sucking Tube

The sucking tube originates from the center of the platform and travels to the manifold. Inside the manifold, it splits into two tubes and connects to a peristaltic pump. If this tube is clogged, it can lead to various printing issues, including blank pages. Don't overlook the capping station's role in printer performance.

Check and Repair the Air Tube

Begin by disconnecting the air tube and attaching a syringe with an adapter. If you feel resistance when drawing air, it indicates a clog in the tube. Use regular tap water in the syringe to flush out the clog until the water runs clear.

Check and Repair the Sucking Tube

The black tube on the left side connects to the peristaltic pump. If you encounter resistance when trying to draw air through it, there may be a clog. Carefully clean this tube to restore proper printer function.

Clean Tubes from the Capping Platform to the Manifold

To ensure ink flow from the platform to the black tube's end, disconnect the tube from the manifold. Using a tool called the "white sucker" available at BCH Technologies, clean this section thoroughly.

Clean the Manifold

Disconnect the clip on the manifold and clean both channels using an unclogging needle. Ensure that ink flows freely through both channels, as any blockage can hinder printer performance.

Clean Tubes inside the Peristaltic Pump

Cleaning the tubes within the peristaltic pump is a more complex process that requires disassembling the entire capping station. If you're not comfortable with this, consider watching our detailed tutorial video on BCH Technologies for step-by-step guidance.

Testing Repaired Capping Station

After completing the cleaning and reassembly process, perform a printer test. Ensure that ink flows smoothly through the tubes, and the platform operates without errors. A self-cleaning routine should run successfully.


Maintaining your printer's capping station is crucial for consistent print quality and preventing costly component replacements. Don't overlook this often-neglected aspect of printer maintenance. By following the steps outlined in this guide, you can troubleshoot and clean your capping station effectively.
