Troubleshooting Epson 8550 Conversion Issues: Ink Flow and Paper Jams Explained

Question:
I recently followed a YouTube guide to upgrade my Epson 8550 using the complete nipple conversion kit and drag chain. After setting everything up, I've run into issues: at first, the ink wasn't coming out, and now only red ink is coming through. I’m also experiencing paper jams, where paper feeds out only to be pulled back in. This is a brand-new printer, so I'm unsure what's going wrong. Could you guide me on what to check or fix?

Answer:
Thank you for reaching out to us! We understand the urgency of printer issues, especially with a new conversion project. At BCH Technologies, we’re always here to support your printing journey and appreciate your engagement with our YouTube channel. Your input helps us continue developing valuable content for all printer enthusiasts.
Based on the details you shared, let’s address your issues with ink flow and paper jamming, primarily since you’ve invested in a full setup with the nipple conversion kit, drag chain, and more.
  1. Paper Jamming Issue
    The paper jam issue could result from the drag chain or printhead carriage getting caught somewhere. With conversions, it's common for components like the drag chain to slightly interfere with the printhead's motion if not carefully aligned. Here’s a step-by-step approach to diagnosing this problem:
    • Open the Scanner Cover: This model doesn't have a sensor to detect if the scanner cover is open, allowing you to observe the printer’s start-up sequence. When you turn on the printer, watch how the printhead moves and see if it catches on anything.
    • Locate the Obstruction: Note where the printhead stops moving. This point is likely where the drag chain or another part obstructs the carriage path. Check that the drag chain isn’t in the way, or perhaps see if it needs slight repositioning to allow smoother printhead movement.
  2. Ink Flow Issue (Only Red Ink Flowing)
    The ink flow problem where only red ink is coming through could be due to trapped air in the ink lines or an incomplete system priming. The DTF ink is thicker than regular ink, so initially it needs a little help to get flowing. Here’s what we recommend:
    • Prime the Printhead: First, park the printhead at the capping station, turn on the printer, and let it naturally rest there.
    • Draw Ink from the Waste Tube: Use a syringe to draw 1 to 2 ml of ink from the waste tube. This can help pull any air bubbles out of the ink lines, which is crucial for establishing a proper ink flow.
    • Run a Cleaning Cycle: Afterward, perform a regular cleaning cycle to push the ink through the channels. Avoid running the printer’s built-in cleaning cycle repeatedly or doing a power cleaning within 12 hours, as overusing cleaning functions can drain ink and stress the printer mechanisms.
  3. Ensuring Consistent Ink Flow
    Since you’re using the conversion kit and drag chain, double-check the entire ink line set-up to ensure no kinks or bends in the tubing, which could lead to inconsistent ink delivery. Also, verify that the cartridges are fully seated and primed.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. At BCH Technologies, we cannot offer remote troubleshooting or repair support, but we provide in-person evaluations through our local diagnostic facility. Please note that, due to demand, we work on a first-come, first-served basis, and it may take a few weeks to arrange your printer’s drop-off or mailing.
We recommend using YouTube’s search function to find additional resources for DIY troubleshooting, including on our YouTube channel. With nearly a decade of content, searching directly on YouTube can be the most efficient way to locate relevant videos for specific issues.
We appreciate your patience and your support. Thank you again for contacting us, and we hope these steps bring you closer to a fully functional, converted printer.
