How to Fix a Clogged Waste Ink System or Capping Station on Epson L1800 DTF Printers

Question:
I have a DSV L1800 printer that has been sitting unused for over a year. I performed a full cleaning, but the printer still isn't printing anything. I suspect the waste ink tank is clogged, but I don't know how to remove it on this model in order to really clean it. Can you help?

Answer:

When a printer sits unused for an extended period, dried ink often clogs not only the printhead but also the capping station and waste ink tubes, which are responsible for drawing ink through the head during cleaning cycles. If the capping station is clogged, it won't form a proper seal, and ink won't flow-even if the printhead itself is clean.

Here are several resources and possible solutions:

1. Removing and Installing the Capping Station

If you need to access the capping station, this guide demonstrates how to remove and reinstall it safely: Removing and Installing the Capping Station (https://youtu.be/_cZEkmgIZYc). This video does not require fully uncasing the printer, but if you find that process too complex, it's often better to let a professional take over.

2. Cleaning a Clogged Capping Station

If the capping station itself is blocked and not sealing properly, you can flush it with cleaning solution. This step-by-step video shows the process: Unclogging the Capping Station (https://youtu.be/WbY_6O1-w2c).

3. Routine Maintenance

Regular upkeep prevents buildup that leads to clogs. This video demonstrates best practices for ongoing care: Capping Station Maintenance (https://youtu.be/5yjq3ZN0qv8).

4. Repairing a Faulty Capping Station

If the capping station is not functioning correctly despite cleaning, this troubleshooting video may help: Repairing the Capping Station (https://youtu.be/5UC2IMu9V90).

5. Rewiring Capping Station Tubes

Clogged or disconnected tubes can prevent ink from being drawn into the waste system. This video explains how to rewire them properly: Rewiring Capping Station Tubes (https://youtu.be/J9im3s8UJfo).

6. Advanced Disassembly Guide

If none of these methods work and the clogging is severe, you may need to disassemble the capping station down to its gears for a complete rebuild. We have an exclusive, detailed video tutorial available here: Capping Station Assembly & Disassembly Guide for L1800/1390/1430/1400 (https://bchtechnologies.com/products/video-capping-station-assemble-disassemble-guide-for-l1800-1390-artisan-1430-and-1400).

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For this reason, we're unable to provide remote troubleshooting, suggestions, or live repair support. However, we do offer in-person evaluations and repairs at our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Service is on a first-come, first-served basis, and due to high demand, it may take a few weeks before your printer can be examined. We can repair either entire printers or specific components, with clear instructions on how to proceed. That said, we recognize our repair rates aren't the most economical, which is why we encourage self-help solutions first. The best place to begin is our YouTube channel homepage (https://youtube.com/@bchtechnologies), where you can use the search function (next to "About" on the menu bar) to quickly find specific tutorials. With nearly a decade of content, this method is often the fastest, and YouTube may also recommend additional helpful videos from other creators.

Thank you again for reaching out and for your support of BCH Technologies. I hope these resources give you the confidence to get your L1800 running again after its long downtime.
