How to Resolve Ink Flow Issues on the Epson WF-7720

Question: I'm trying to fix an Epson WF-7720 printer and recently noticed that one of the colors wasn't being utilized during printing. I've tried several potential fixes found on YouTube, but none have completely resolved the issue. While I managed to get two cartridges working at one point, none of them are printing now. I'm using OEM cartridges. Could you advise on the best strategy to get all inks flowing through the printhead? What products do you offer that might help?

Thank you for reaching out to BCH Technologies. We truly appreciate your engagement and support, especially with our YouTube channel, BCH Technologies on YouTube. Your feedback is essential in helping us further enhance our technical expertise.

Addressing ink flow issues with your Epson WF-7720 can be a bit tricky, but let's walk through some steps that might help you get your printer back in working order.

  1. Check for Clogged Nozzles: The most common cause of missing colors in prints is clogged nozzles. Even though you are using OEM cartridges, clogs can still occur over time due to ink drying up or debris accumulation. Start by running the printer’s built-in cleaning cycle several times. This might help dislodge any dried ink from the nozzles.

  2. Manual Printhead Cleaning: If the automated cleaning cycles don’t solve the issue, you may need to perform a manual printhead cleaning. Remove the printhead from the printer (if your model allows it) and use a printhead cleaning solution to flush out the dried ink. We offer a Printhead Cleaning Kit [https://bchtechnologies.com/printhead-cleaning-kit] specifically designed for Epson printers, which can be very effective in restoring ink flow.

  3. Inspect the Cartridges: Although you mentioned using OEM cartridges, it’s still worth checking to ensure that the cartridges are properly seated and have not expired. Expired ink cartridges can cause issues with ink flow. Make sure the air vent on each cartridge is open and not blocked, as this could prevent ink from flowing properly.

  4. Perform a Power Cleaning: Epson printers have a more intensive cleaning process called “Power Cleaning.” This option uses more ink but is more effective at clearing stubborn clogs. Access this feature through your printer's maintenance menu, and follow the on-screen instructions.

  5. Consider Ink Priming: Sometimes, air bubbles trapped in the ink lines can cause ink flow problems. Ink priming tools can help remove these bubbles. We recommend our Ink Priming Tool Kit [https://bchtechnologies.com/ink-priming-tool-kit], which is compatible with Epson printers and can assist in re-establishing proper ink flow.

  6. Check for Firmware Updates: Occasionally, firmware updates can resolve printing issues by improving the printer’s handling of ink flow. Check the Epson Support website for any available updates and install them.

  7. Test Different Paper Types: Believe it or not, the type of paper you use can sometimes affect ink flow. Make sure you are using the appropriate paper type for your printer and the ink you are using. Some printers are more sensitive to this than others.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility BCH Technologies Printer Repair Service [https://bchtechnologies.com/printer-repair-service]. Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get to your printer if you drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage [https://youtube.com/@bchtechnologies]. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you again for contacting us, and we hope this information helps you resolve the issue with your Epson WF-7720. If you require further assistance or decide to bring in your printer for repair, feel free to reach out.
