Where to Buy a Reliable Replacement Printhead for Epson WF-3640 (Fixing Error 0x97 or 0xEA)

Customer Question:

After trying all the extreme unclogging steps on my Epson WorkForce WF-3640 and still getting no prints, I’m now looking for a quality replacement printhead. I’ve tried buying from eBay, Alibaba, and Amazon, but the printer doesn’t recognize the ones I received, or they don’t print. Are there any reliable online sources where I can purchase a dependable printhead?

Understanding the Epson WF-3640 Printhead Issue and Where to Buy a Replacement

Printhead Failure Symptoms

After attempting extensive printhead unclogging and still seeing no output—especially if you're encountering error codes like 0x97 or 0xEA—there's a strong possibility that the printhead is either electrically damaged or mechanically compromised.

• Error 0x97 typically indicates a hardware-related failure, often linked to the motherboard or the printhead.

• Error 0xEA usually points to carriage movement problems, but can also occur due to a disconnected or faulty printhead.

In such cases, replacing the printhead becomes the logical next step. But as you've rightly pointed out, finding a genuine and fully functional printhead online has become more challenging in recent years.

Common Pitfalls with Online Printhead Sources

Many sellers on eBay, Alibaba, and even Amazon claim to offer OEM or compatible parts, but:

• They often ship refurbished units that aren't fully tested.

• Some are third-party replicas, which may not communicate correctly with your printer’s firmware.

• In many cases, printheads arrive DOA (dead on arrival) or trigger cartridge recognition errors.

• Return policies on platforms like Alibaba can be difficult to navigate or enforce.

Our Recommendation

At BCH Technologies, we do keep a limited inventory of replacement printheads specifically for use in our internal repair operations. However, we understand the difficulty many customers face in sourcing high-quality components. If you are truly unable to find a dependable source elsewhere, we’re willing to spare one or two units from our stock to assist customers in need.

If you decide to pursue this route, please contact us directly through our repair service page (https://bchtechnologies.com/printer-repair-service) and mention this discussion. We’ll provide further details regarding availability, compatibility, and pricing.

That said, even with a replacement, make sure to:

• Update your printer’s firmware, if applicable.

• Ensure proper seating and alignment of the printhead ribbon cables.

• Run a cleaning cycle immediately after installation to ensure full ink priming.

A Few Additional Notes

Dealing with printhead replacement and persistent hardware errors is one of the more involved aspects of printer maintenance. Because of the hands-on nature of this process, we’re unable to provide individualized remote troubleshooting or technical support. However, we do offer in-person evaluation and repair services (https://bchtechnologies.com/printer-repair-service) through our diagnostic facility. Due to high demand, please note that we operate on a first-come, first-served basis, and wait times may apply.

While our pricing structure may not always be the lowest, our services include thorough testing and part validation. That said, if you'd prefer a DIY approach, we strongly encourage exploring trusted online resources. Begin with our YouTube channel homepage (https://youtube.com/@bchtechnologies), and use the search icon next to the “About” tab to locate specific troubleshooting videos. With over nine years of content, this method is usually the fastest way to find help. Plus, YouTube’s algorithm might surface relevant videos from other helpful channels too.
