Question:
I’ve been using your videos to guide me through setting up my Epson ET-8550 for DTF printing, and they’ve been a great help—thank you!
I recently purchased a CISS (Continuous Ink Supply System) for my printer and initially got good DTF prints. However, I’m encountering a problem where the yellow ink dries up and hardens inside the tubes very quickly. Interestingly, this issue doesn’t happen with other colours like white, black, cyan, or magenta.
I’m considering purchasing the "DTF Printhead Management Assembly" from your site to clean out the yellow and white lines. Would it help with this issue?
Additionally, I’ve run into an Error 031006. After inspecting the printhead and cables, I found no signs of damage, but my multimeter shows no continuity on the F fuse. Would replacing the F fuse resolve this error?

Thank you for contacting us, and we’re sorry for the delay in addressing your concerns. We understand how frustrating printer issues can be and appreciate your patience as we carefully consider every detail of your situation. At BCH Technologies, we value your support of our YouTube channel (https://youtube.com/@bchtechnologies), and your engagement helps us improve our technical offerings.
To address your questions:
We recommend using a replacement fuse like our F1 Fuse for Epson Mainboards (https://bchtechnologies.com/products/f1-fuse-also-f2-f3-for-epson-mainboard-fix-error-0x9a-or-031006-on-wf-7720-wf-7710-wf-3640-et-8550-xp-15000). After replacing the fuse, monitor the mainboard closely. If the printhead is faulty, it could cause a short again, damaging the mainboard and requiring additional repairs.
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For this reason, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. However, we do offer an in-person evaluation and repair service (https://bchtechnologies.com/printer-repair-service) through our local diagnostic facility. This service is structured to repair the entire printer or specific parts, with clear instructions on how to proceed.
Our repair service operates on a first-come, first-served basis, and demand is high, so there may be a wait before your printer can be evaluated. If you want more help, we encourage you to explore self-help resources, starting with our YouTube channel (https://youtube.com/@bchtechnologies).

To address your questions:
Yellow Ink Drying in Tubes
Yellow ink is generally the least likely to clog. If it’s hardening in the tubes while other colours like white, black, cyan, and magenta remain unaffected, your setup may have an underlying issue. Possible causes include:- Leaking Damper: A defective or improperly sealed damper can lead to inconsistent ink flow.
- Unprimed Yellow Tanks: If air has entered the yellow ink system, it could cause the ink to dry out prematurely.
- Blockage in the CISS System: Examine the yellow ink tube and its connections for clogs or obstructions.
- Environmental Factors: Heat or exposure to air could exacerbate ink drying.
Resolving Error 031006 and Replacing the F Fuse
The 031006 error often indicates a short in the mainboard, which may occur even if the printhead and cables appear fine. If your F fuse shows no continuity on the multimeter, replacing it is the logical next step.We recommend using a replacement fuse like our F1 Fuse for Epson Mainboards (https://bchtechnologies.com/products/f1-fuse-also-f2-f3-for-epson-mainboard-fix-error-0x9a-or-031006-on-wf-7720-wf-7710-wf-3640-et-8550-xp-15000).
