Epson Error W-13 — What It Means & How to Fix It
Updated July 2026 · Independent PrinterCare USA support guide
The W-13 incompatible ink cartridge warning is one of the most common Epson printer errors, and it stops your machine from printing until you address it. This error triggers when your printer's sensors detect cartridges that don't match Epson's authentication chip standards—this can happen with refilled cartridges, third-party supplies, or even genuine cartridges with damaged contacts.
The good news is that this error is almost always fixable without a technician visit. In most cases, simply reseating your cartridges or replacing them with genuine Epson products resolves the issue completely. We'll walk you through every troubleshooting step, from the simplest fixes to advanced contact cleaning techniques.
How to fix it — step by step
- Power cycle your printer completely. Turn off your Epson printer using the power button, then unplug the power cable from the wall outlet. Wait for at least thirty seconds to allow the printer's memory to fully reset. Plug the power cable back in and turn the printer on again, then check if the W-13 error message has cleared.
- Remove and reseat all ink cartridges. Open your printer's cartridge access door and locate each ink cartridge. Gently push each cartridge inward until it clicks firmly into place, ensuring no cartridges are sitting at an angle or partially inserted. This is the most common cause of W-13 errors, as loose cartridges trigger the incompatibility warning even if they are genuine.
- Check cartridge authenticity and expiration. Examine each cartridge for Epson branding and security holograms on the packaging or cartridge itself. Look for an expiration date on the cartridge—expired cartridges may trigger compatibility warnings even if they are genuine. If you are using third-party or refilled cartridges, this is likely the source of the error, and switching to genuine Epson cartridges will resolve it.
- Inspect cartridge contacts for debris. Remove each cartridge one at a time and look at the metal contact pins on the cartridge's underside. If you see dirt, dried ink, or discoloration on the contacts, gently wipe them with a lint-free, dry cloth. Do not use water or cleaning solutions, as moisture can permanently damage the cartridge authentication chips.
- Clean the cartridge slot contacts inside the printer. While cartridges are removed, look inside each cartridge slot in your printer and inspect the metal contacts for debris or corrosion. Using a dry cotton swab or soft brush, gently clean the contacts inside the printer. Make sure no lint or fibers are left behind, and allow the contacts to air dry for two minutes before reinserting cartridges.
- Replace with genuine Epson cartridges if needed. If you have been using third-party or refilled cartridges, purchase genuine Epson cartridges that match your specific printer model number. Install them following the printer's cartridge installation guide, ensuring each cartridge seats fully with an audible click. Run a test print to confirm the W-13 error has resolved.
- Update your printer firmware. Visit the official Epson support website, locate your printer model, and download the latest firmware version if one is available. Follow Epson's firmware update instructions carefully, as an interrupted update can cause additional errors. After updating, power cycle your printer and attempt to print again.
- Contact Epson support or schedule a remote diagnostic. If the W-13 error persists after all previous steps, the cartridge authentication chip may be permanently damaged, or your printer's sensor may require recalibration by Epson. You can schedule a remote diagnostic session for forty-nine dollars, during which a technician will connect to your computer to run advanced diagnostics and attempt resolution. Alternatively, contact Epson support directly for warranty service if your printer is still under coverage.

Frequently asked questions
Will third-party cartridges always trigger the W-13 error?
Most third-party and refilled cartridges will eventually trigger the W-13 error because they lack Epson's proprietary authentication chip or the chip is non-functional. Some third-party cartridges with clone chips may work temporarily, but they are unreliable and often trigger warnings within a few months. Using genuine Epson cartridges is the only way to permanently eliminate W-13 errors caused by incompatibility.
Can I clear the W-13 error without replacing my cartridges?
Yes, if you are using genuine Epson cartridges and the error is caused by poor contact or a temporary sensor glitch, reseating the cartridges and power cycling the printer will clear it. However, if you are using third-party cartridges, the error will return repeatedly unless you switch to genuine supplies. Cleaning the cartridge and printer contacts can also resolve the issue if the contacts are dirty.
Is the W-13 error a sign that my printer is broken?
No, the W-13 error is almost always caused by incompatible cartridges or poor cartridge contact, not a hardware failure. Only in rare cases does the error indicate a faulty cartridge sensor that requires professional repair. Follow the reseating and cleaning steps first—these resolve the error ninety-five percent of the time.
Why does my printer show W-13 even after I installed new genuine Epson cartridges?
New genuine cartridges can still trigger W-13 if they are not fully seated, if the cartridge authentication chip was damaged in shipping, or if the printer's sensor contacts are dirty. Remove the new cartridges and reseat them with firm pressure until each one clicks into place. If the error continues, clean both the cartridge contacts and the printer's internal contacts with a dry cloth, then reinstall the cartridges.
