Epson ET-8850 Printer Clogging Issues – Cleaning Tips and Printhead Replacement Guide

Question:
I run multiple Epson ET-8850 printers, and recently, one has started experiencing frequent clogging issues despite using genuine Epson ink. I use these printers heavily for A3 and A4 poster printing. Before buying parts from your site, I'm considering getting your cleaning kit and possibly soaking the printhead overnight. If cleaning doesn't resolve the issue, can I swap the printhead from another Epson model like the XP-970? Are there other cleaning or maintenance upgrades you recommend for better performance?

Understanding and Resolving Clogging Issues in Epson ET-8850

Since you're already using genuine Epson inks, unclogging typically becomes straightforward. However, frequent clogging in high-volume usage scenarios often indicates wear and tear rather than actual nozzle blockage. Over time, even well-maintained printheads can degrade internally, causing inconsistent print quality despite thorough cleaning.

Recommended Steps for Cleaning Your Printhead

  • Basic Cleaning: Start with our specialized cleaning kit designed specifically for Epson printers. This kit safely dissolves stubborn ink residue without damaging the printhead.

  • Overnight Soak: If basic cleaning doesn't fully resolve the issue, soaking the printhead overnight in a gentle cleaning solution can significantly help dissolve more persistent ink deposits.

  • Avoid Aggressive Internal Printer Cleaning Cycles: Steer clear of frequent use of Epson's built-in "Strong Cleaning" function. Excessive use of this feature can prematurely degrade your printhead.

Replacing the Printhead

If cleaning doesn’t restore your printer's performance, replacing the printhead is a viable solution:

  • Printhead Compatibility: You can safely swap printheads from similar Epson models like the XP-970, as they share compatible printhead designs with the ET-8850. This replacement should be straightforward if the printheads are identical models.

  • Purchasing a Replacement: Consider purchasing refurbished printheads through reputable sources, such as Epson’s certified refurbishment programs on eBay. These refurbished units are reliable and typically less costly than new replacements.

  • Potential Limitations: Be aware Epson occasionally seals refurbished printheads to prevent modifications. However, since your intended use involves no custom modifications, this shouldn't pose a problem.

Additional Maintenance Recommendations

  • Regular Maintenance Routine: Establish a regular cleaning and maintenance schedule to prevent ink from drying and accumulating inside the printhead.

  • Humidity Control: Maintain consistent humidity levels in your printing area, as very dry conditions can exacerbate clogging issues.

  • Ink Usage: Continue using genuine Epson ink, as it significantly reduces clogging compared to third-party alternatives.
