Question:
I’m having trouble with my brand new Enjoy Color A3+R DTF printer and its oven. The printer’s top right and middle lights are blinking red, and the oven isn’t heating up properly. We have large orders to fulfill, so I need help figuring out what’s going on and how to fix it quickly.

Answer:
Thank you so much for contacting us, and I truly apologize for not being able to respond to your urgent issue sooner. We absolutely understand how critical it is to keep your DTF printer and oven operational—especially when you have customer orders waiting. Every printer issue deserves thoughtful and detailed attention, and we’re committed to helping you navigate through this. Here at BCH Technologies, we’re also very thankful for your engagement and support, especially through our YouTube channel (https://youtube.com/@bchtechnologies). Your feedback helps us develop better tools and guides for users in the DTF printing community.

Now, let’s address the problem with your Enjoy Color A3+R printer and the oven not heating up.


🔴 Blinking Red Lights on the Printer

The blinking red lights—particularly the top right and middle indicators—are typically warning signals triggered by internal system checks. On Epson-based DTF printers like the Enjoy Color A3+R, these alerts usually point to sensor errors, ink system issues, or mainboard communication faults.

To get a specific diagnosis, you’ll need to run Epson’s Adjustment Program, a utility tool used to extract internal error codes:

🔧 How to Check Error Codes Using the Adjustment Program:

  1. Launch the Adjustment Program for Epson printers. (This software is often shared by DTF printer suppliers or can be found via online forums—searching for “Epson Adjustment Program download” might help.)

  2. Select your printer's USB port from the dropdown menu.

  3. Click “Particular Adjustment Mode”.

  4. Scroll down and select “Printer Information Check.”

  5. Click “Check” and read the first listed error under "Error number 1." This will be the most recent and most likely cause of the red lights.

Once you have that error code, search “BCH Epson Error” on Google. This will bring you to our resource explaining Epson’s Triple Secret Error Codes, including potential meanings like:

  • APG Sensor error

  • Carriage error

  • Waste ink pad reset needed

  • Or heater-related faults

We also have a quick visual walkthrough you can watch on our YouTube channel here (https://youtube.com/shorts/FPZzpyYuZLE).


🌡️ Oven Not Heating Up

The oven issue is a separate but common challenge with DTF setups. If the heating element isn’t reaching the proper temperature, it could be due to:

  • A failed heating element

  • A blown thermal fuse

  • A damaged relay on the control board

  • Or incorrect thermostat or sensor feedback

If you can open the oven's bottom panel, you may want to check whether the heating coil is visibly damaged or if the fuse has continuity using a multimeter. Unfortunately, these ovens are often built with minimal diagnostics, so trial and error or part replacement may be necessary unless the vendor provided a service manual.


Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. As such, we're unable to offer remote, case-by-case technical support or perform remote repairs. However, we offer in-person diagnostic and repair services (https://bchtechnologies.com/printer-repair-service) at our facility. Please be aware that our services are offered on a first-come, first-served basis, and there may be a waiting period due to high demand. Our repair offerings include complete printer servicing or targeted part replacement, with detailed communication throughout. We recognize that our service rates may not suit everyone’s budget, so we highly recommend starting with self-research. You can explore our YouTube channel (https://youtube.com/@bchtechnologies) and use the search icon near the "About" section to find content related to your specific model or issue. This can often be the fastest and most effective way to find a fix—even from other helpful channels.

Thanks again for reaching out to us. We hope this helps you troubleshoot both your printer and oven so you can get back on track with your orders as soon as possible. We’re here if you need additional guidance on replacement parts or deeper diagnostics.
