Reviving Your Printer: How to Fix Black Ink Not Printing on EcoTanks?

Q: After buying a used printer that turns out to have a high print count, the black ink won't print despite attempts at flushing. What steps can I take to solve this issue?

A: It's disappointing to encounter issues with a newly acquired printer, but don't worry, there are several steps you can take to diagnose and potentially solve the problem. Let's walk through the process:

1. Perform a Nozzle Check: This is your first diagnostic tool. It will show you if there are any missing segments or if a particular color, in this case, black, is not printing at all. A nozzle check can often reveal underlying issues that aren't immediately apparent.
2. Check the Ink Supply System: After ensuring all colors except black are fine, it's crucial to examine the ink supply to the black nozzle. This involves priming the dampers, which are responsible for delivering ink from the reservoir to the printhead. Clogs in this area can prevent ink from reaching the printhead.
3. Tube Troubleshooting: Often, the problem lies within the tubes that transport ink, especially in high-usage printers where ink residue can build up over time. The issue might be simpler to address than expected. Begin by disconnecting the tubes from the printhead to inspect and clear any blockages. If the clogs are persistent or the tubes are damaged, replacing them might be necessary. Our "Ecotank tubes" available on the BCH Technologies website are suitable for many models and can be a reliable replacement option.
4. Tube Cleaning Technique: If you opt for cleaning the existing tubes, carefully remove them from the printer and soak them in warm water. This helps loosen the ink clogs. Gently massage the tubes, paying extra attention to clotted areas. Using a syringe to draw air through one end of the tube can help ensure that the ink will flow smoothly once reconnected.
5. Damper Priming: Air trapped in the dampers can prevent ink from flowing correctly, necessitating priming. Use a syringe to gently draw ink into the damper until you see ink in the syringe, indicating that the damper is primed and ready for use.
6. Built-in Cleaning Cycles: If the ink supply to the printhead is confirmed and all physical blockages have been cleared, utilize your printer's built-in cleaning cycles. These functions are designed to clear out any remaining clogs within the printhead itself. Follow a structured schedule of cleaning cycles, allowing the printer to rest in between, to avoid overworking the printhead.
7. Maintenance Tips: To maintain optimal functionality and prevent future clogs, consider adopting a regular maintenance routine. This includes printing a page or two daily to keep ink flowing through the printhead and performing periodic nozzle checks and cleaning cycles as preventive measures.

By following these steps, you should be able to address the issue of black ink not printing in your high-usage printer.
