Ink Errors on the Epson L1800 DTF Printer

Question: What should I do if my Epson L1800 DTF printer does not recognize ink and shows a solid red ink light even after replacing the motherboard, printhead, and ink cables?

Thank you for reaching out with your query, and we appreciate your support, especially in following our BCH Technologies YouTube Channel. Your involvement is crucial in enhancing our collective technical knowledge at BCH Technologies.

Regarding your Epson L1800 DTF printer not recognizing ink and displaying a solid red light despite the recent hardware replacements, it's important to note that the Epson L1800 DTF model does not use traditional ink cartridges, which means it won’t check cartridges as a cause of the error.

Here’s a detailed approach to resolving your printer’s ink error using the Epson Adjustment Program:

1. Initiate the Adjustment Program: This tool is essential for diagnostics and adjustment settings. Access the Adjustment Program available from Epson’s support or authorized providers.
2. Proceed to Particular Adjustment Mode: This section allows you to make specific adjustments relevant to your printer’s issues.
3. Perform a Printer Information Check: Navigate to "Printer Information Check" and click the "Check" button. This action will provide a set of error codes, with the most recent appearing at the top. These error codes are key to pinpointing the specific malfunction.

For the Epson L1800's ink light to remain steadily on, there are typically two scenarios to consider. Firstly, the steady ink light could simply serve as a warning that the printer requires an initial ink charge. This is a common requirement after installing a new mainboard, as you have done. Performing an initial ink charge should resolve this issue and the light should turn off. The initial ink charge can be performed either from your computer, or holding the ink button for more than 3 seconds then release it. Secondly, if a reset of the printer is necessary (often indicated by a restart), all the control panel lights, not just the ink light, would typically be illuminated. If only the ink light is on, it suggests that the first scenario is more likely.

• Initial Ink Charge Needed: Given that you’ve installed a new motherboard, the printer may require an initial ink charge. This procedure is typical after such hardware changes to ensure the ink system is fully operational. Completing an ink charge should extinguish the red ink light.
• Need for Printer Reset: If all button lights were illuminated, this would indicate a need for a complete printer reset. However, since only the ink light is active, this is less likely but still worth considering if problems persist after an ink charge.

Addressing printer issues often involves intricate, hands-on troubleshooting. For example, resolving a simple clog might require specific unclogging steps. Conversely, a long period of inactivity might necessitate a thorough service of the entire ink system. Moreover, a "paper jam" might stem from numerous potential causes, and addressing such problems is a frequent topic of discussion among our technicians.
