Question:
Can BCH Technologies repair and modify my Epson ET-8550? I’ve converted it to DTF for our small family business, but it recently showed error code 031004. I suspect the printhead, FFC ribbon, and fuse, along with some DTF ink leakage, might be damaged. I’m in California and want to estimate whether repairs and modifications are possible.Answer:
Thank you for reaching out to us with your Epson ET-8550 concerns. We apologize for not being able to address your query sooner. Printer issues, especially with DTF conversions, are often urgent, and we’re committed to giving each case the attention it deserves. At BCH Technologies, we’re also grateful for your engagement and support, especially with our YouTube channel. Your feedback is essential in helping us continue to grow our technical knowledge.Let's discuss the potential issues and repairs to address error code 031004 on your Epson ET-8550. Error code 031004 typically indicates a printhead issue, likely compounded by the challenges posed by DTF (Direct-to-Film) ink. If not handled with specific techniques, DTF ink’s viscosity and unique formulation can lead to clogging, leakage, and even internal damage.
Your printhead may be damaged from DTF ink, especially if the ink has leaked into critical areas or the fuse and FFC ribbon have been compromised. The best approach would be a full assessment to identify whether replacing the printhead or additional components is needed.
Here’s some insight into our DTF conversion approach and policies, particularly for mail-in repairs. Typically, we handle new or local printers for DTF conversion to ensure quality testing. With local printers, we can control the process from start to finish, including testing with DTF ink, as the printer can be picked up promptly, avoiding ink sitting unused for prolonged periods. With mail-in DTF conversions, however, it becomes challenging to guarantee the printer will arrive in perfect condition. Variances in shipping and initial priming by the customer can impact performance.
In some cases, we waterproof the printhead to reduce ink seeping, but waterproofing only prevents ink from dripping or seeping externally; it does not prevent internal leaks that can occur due to frequent vigorous cleanings. Epson, for instance, advises waiting 12 hours between strong cleanings, as aggressive cleanings too close together can exacerbate internal leakage. For example, one mail-in customer reported damage despite waiting 18 hours, yet local handling could have prevented such issues.
We ensure the printer is DTF-ready for any mail-in conversions and provide documentation to confirm the printhead function. However, the customer will be responsible for ongoing maintenance and priming of the printhead. The printer should perform well with DTF inks if done correctly, but proper handling is critical.
As for modifications, we offer:
- Waterproof Printhead: This is used to reduce external leakage risks.
- Nipple Conversion with V2 Dampers: Essential for DTF ink handling.
- Drag Chain Installation: Prevents tubing from snagging during operation.
