How to Fix "No Paper" Error and Flashing Middle Light on a DTG Printer: Troubleshooting Guide

Question:

My DTG printer shows a "no paper" error, and the middle light is flashing. I’ve already refilled the ink, but I still can’t print. How do I fix this?

Answer:

Thank you very much for contacting us, and I sincerely apologize for not being able to get back to you sooner. I understand how frustrating it can be when printer problems interrupt your workflow, especially with something as time-sensitive as DTG printing. That’s why I want to give your question the thoughtful, specific answer it deserves. We at BCH Technologies are genuinely grateful for your continued engagement and support, primarily through our YouTube channel (https://youtube.com/@bchtechnologies). Your questions and feedback help us stay sharp and improve the quality of the content we share with the printing community.

Now, let’s walk through your issue carefully.

Fixing the “No Paper” Error and Flashing Middle Light on a DTG Printer

This “no paper” message and the middle indicator light flashing (commonly on converted Epson printers like the L1800, R2400, 1390, etc.) can typically be traced back to a few possible causes, none related to ink levels. Here’s how to approach the problem step-by-step:

1. Identify the Base Printer Model

Most DTG printers are built by modifying Epson models. Understanding your printer’s original model (e.g., Epson L1800, 1390, R2400) will help you troubleshoot more effectively. The behavior of these models is reasonably consistent, even when modified for DTG use.

2. Check the Print Mode Settings in the Driver or RIP

Since you’re printing onto a platen instead of feeding paper, ensure your driver or RIP software is configured accordingly. The printer won't proceed with the print job if it’s still set to expect paper input (like from the tray).

• Set the paper source to “Front Manual Feed” or “No Paper Feed.”

• Disable automatic paper detection if the software or driver allows it.

This alone resolves the error, especially when using RIP software that doesn’t auto-adjust for DTG workflows.

3. Clean and Inspect the Paper Feed (PE) Sensor

The middle light flashing is typically related to a paper detection issue. The Paper End (PE) sensor or Paper Feed Encoder detects whether media is loaded.

Common issues:

• Dirt or ink overspray: Clean the sensor using compressed air or a lint-free swab dampened with isopropyl alcohol.

• Garment lint or debris: Fibers can build up around the sensor, especially if you frequently print on shirts.

• Sensor misalignment: During DTG conversion, some sensors are relocated or removed. Make sure yours is not loose or disconnected.

4. Evaluate the Carriage Movement

When powered on, does the carriage move properly from side to side? If the printer is attempting to feed paper and fails, it may:

• Assume paper isn’t present,

• Trigger the flashing middle light, and

• Halt the job.

Ensure nothing obstructs the carriage path and that all belts and gears are moving as expected.

5. Simulate Paper Presence (Advanced Users Only)

If your printer has been heavily modified for DTG use and lacks physical paper detection mechanisms, you may need to trick the printer:

• Use a small white paper or reflective tape near the paper sensor to simulate loaded paper.

• Hardware bypass: Some users solder a jumper or resistor instead of the PE sensor, which is especially common on Epson L1800 DTG conversions. Only do this if you are comfortable with basic electronics.

6. Perform a Power Cycle

It sounds simple, but it’s often effective:

• Turn off the printer.

• Unplug it for 1–2 minutes.

• Power it back on and try again.

This can reset minor errors in the logic board or firmware.

7. Use the Epson Adjustment Program (If Applicable)

If your DTG printer still runs on an Epson logic board, you can try the Epson Adjustment Program to:

• Reset the paper feed counter, and

• Diagnose internal errors or firmware flags.

This can also be used to check for service errors, though caution is advised as improper use may brick your printer.

A Final Note:

Tackling printer problems, especially with converted DTG units, often involves a fair bit of hands-on work. Unfortunately, due to the physical and customized nature of these printers, we can’t offer remote support or step-by-step repairs. However, we do provide in-person printer evaluation and repair services at our diagnostic center (https://bchtechnologies.com/printer-repair-service). Due to high demand, appointments are on a first-come, first-served basis, and wait times may extend several weeks. Our repair services are flexible—covering either full-printer diagnostics or targeted part replacements. That said, we understand our prices may not fit every budget. So we encourage self-service options such as researching via YouTube. You can start by visiting our YouTube homepage (https://youtube.com/@bchtechnologies). Use the search icon beside the "About" tab to quickly locate videos on specific issues. With over nine years of video content, it’s the fastest way to find what you need—and YouTube may even surface related videos from other creators that help you as well.

Thank you again for reaching out. We truly appreciate your support and wish you the best of luck resolving this DTG printer issue. Let us know if there’s anything else we can do to help!
