Troubleshooting Recurring Red Light and Printing Issues on Epson 1390-Based DTF Printers.

Question:
I have an Epson 1390-based DTF printer that’s been having persistent issues. A few months ago, it displayed a recurring red light error. I replaced the capping station and printhead and was advised to change the CR motor. After replacing the engine, the red light error stopped, but the printer slowed down halfway through printing.
I then replaced the mainboard, but the issue continued. The company suggested replacing the motor and the mainboard simultaneously, which I did, but it still hasn’t resolved the problem. They’ve now told me the only remaining option is to have the printer serviced. I hate to throw it away and would appreciate any advice on what else I can try to fix it.
Answer:
Thank you for contacting us and sharing the details of your printer issue. We apologize for the delay in responding, as we understand how urgent and frustrating printer malfunctions can be. At BCH Technologies, we aim to provide thoughtful and specific solutions to every inquiry. Your engagement and support, especially with our YouTube channel (https://youtube.com/@bchtechnologies), mean a great deal to us and help us continue refining our expertise.
The CR motor you mentioned is an OEM (original equipment manufacturer) part. Still, the size difference you noted suggests it might not align perfectly with the rest of the printer’s system. Compatibility in these cases isn’t just about fitting the part—it’s also about ensuring the motor syncs with the rest of the machine, especially with older components.
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot provide remote troubleshooting, suggestions, or support for printer repairs. However, we offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service).
Given the high demand, we operate on a first-come, first-served basis, so scheduling your printer drop-off or mail-in service might take a few weeks. Our services are structured to repair either an entire printer or specific components. We provide clear instructions on how to proceed if you choose mail-in or local drop-off options.
We acknowledge that our rates may be less economical, so we highly recommend self-help resources. Start with our extensive YouTube channel (https://youtube.com/@bchtechnologies). Use the search bar to locate videos related to your issue or explore suggested content from other creators. With nine years of content, you’ll likely find a helpful resource tailored to your needs.
Thank you again for reaching out. We hope these suggestions guide you toward a resolution for your printer. Your support inspires us to continue creating solutions for printer troubleshooting and maintenance.

Analyzing the Problem
Your printer's recurring red light errors, coupled with the persistent slowdown during printing, are challenging issues that may stem from how 1390-based printers are assembled. Unlike some L1800 printers, which may include new components, all Epson 1390-based printers are built from salvaged and refurbished parts. This mix of old and new elements can create consistency and performance issues.The CR motor you mentioned is an OEM (original equipment manufacturer) part. Still, the size difference you noted suggests it might not align perfectly with the rest of the printer’s system. Compatibility in these cases isn’t just about fitting the part—it’s also about ensuring the motor syncs with the rest of the machine, especially with older components.
Possible Issues to Investigate
-
Mechanical Adjustments:
- Could you check the rod alignment to ensure it does not cause excess friction during printing? Misalignment can strain the motor, leading to slower print speeds and inconsistent performance.
- Could you look over the belt tension? A belt that is too loose or too tight can cause erratic printing behaviour and stress the motor. Could you please adjust it to the recommended tension?
- Please make sure all moving parts are adequately lubricated. Lack of lubrication can lead to increased resistance, slowing the printer mid-operation.
-
Electrical and Software Considerations:
- Could you verify the firmware version and any associated software settings? Sometimes, older firmware may need to communicate more effectively with newly installed parts, such as the CR motor and mainboard.
- Inspect the power supply unit (PSU). Inconsistent power delivery can cause intermittent slowdowns, especially with salvaged components.
-
Motor Compatibility:
- Even if the motor is an OEM part, differences in size and specifications might still affect its efficiency. Could you try sourcing a motor that matches the original dimensions of the part it replaces?
-
Printhead and Capping Station:
- Please make sure the printhead and capping station replacements are installed correctly. A poorly seated printhead or a misaligned capping station can contribute to operational errors and slowdowns.
Suggested Next Steps
Unfortunately, diagnosing and resolving such intricate issues often requires hands-on inspection by a professional repair technician. While we don’t currently accept mail-in printers due to high demand, we encourage you to use tools like Google Maps to find a local printer repair specialist. A professional can evaluate the mechanical, electrical, and software components in person and determine the root cause of the slowdown.Addressing printer issues can be a complicated affair due to the hands-on nature of the problems.
