Despite a supreme court ruling in favor of third party ink suppliers, printer manufacturers remain relentless in their quest to eliminate cheaper ink alternatives. Everything from issuing stealth firmware updates disguised as security patches, to questionable takedown notices on eBay, these companies are determined to make consumers pay for their high cost ink.
For Epson, new firmware updates are applied by default as part of the routine software update checks. Although the firmware frequency varies by model, many printers were issued a January 2018 update that effectively disabled the majority of third party ink cartridges. Printers affected by this will suddenly receive notices that one or more ink cartridges are unrecognized, incompatible or non-genuine. The company expects you to replace the ink with their much more expensive name brand format in order to continue using the printer at all (e.g., $100.95 from Epson's shop for the full 410XL ink pack, versus $27.79 by a competing ink remanufacturer).
Luckily, it is usually possible to restore an older version of the printer's firmware and resolve these newfound and self-imposed incompatibilities. The difficult part is figuring out how, since printer companies are notorious for removing old firmware as soon as the new version gets released and they rarely document how to get the printer into recovery mode or transmit older firmware.
This guide is for the Epson XP series and should work on any model from 300 through at least 630, and likely many others with minor adjustments in the instructions. Please refer to the video for an illustrated demonstration.
- Connect a USB cable from the printer to a computer or laptop. When in recovery mode, a USB connection is required to transfer the firmware to the printer, even if you already have it connected wirelessly.
- Remove all of the ink cartridges from the printer. This will ensure that all cartridge-related errors will be reset after applying the alternate firmware.
- Power off the printer. As soon as the printer is completely shut down, press and hold the STOP button, LEFT ARROW button, HOME button and POWER button simultaneously until the firmware update screen appears. If the printer instead boots to its regular screen, you may have to look-up the proper recovery mode combination for your printer model.
- Download the older firmware onto the connected laptop or computer. It may take some research to find the desired firmware, since most printer manufacturers remove obsolete firmware from their site immediately and provide no downgrade instructions. Epson's printers use a self-installing firmware updater that can be run directly from Windows or MacOS. In the case of the XP-630, the earliest firmware update that is the most compatible with third party cartridges is NQ10F8 from 2015. A direct link to some older XP-630 firmware versions is below; for other models you will want to research compatible firmware.
- After launching the downloaded firmware installer, step through the wizard by following the on-screen instructions. In the case of Epson, you mostly have to click next through a few pages of disclaimers. Assuming the printer is connected to the PC with a USB cable and powered up to the recovery screen, you should see a single entry in the Model list and it should be checked. Click Start to begin the firmware downgrade, and then click Yes to confirm. The prior firmware will be transferred to the printer, where it will begin flashing automatically. This process can take several minutes, but when it is completed the on-screen display will indicate that it has finished.
- Once the downgrade is complete, press OK or unplug the printer to power it off. Then power it on again. When prompted, insert the ink as usual and then let the printer complete the ink initialization.
If all of the instructions have been followed successfully, you should no longer receive errors about incompatible ink when using third party cartridges and will be free to print once again. Make sure to disable or otherwise ignore any prompts to update the firmware again to avoid this happening in the future. For Epson, you can uninstall Epson Software Updater as an extra precaution, or simply remember to always uncheck the firwmare updates when prompted (it is safe to update the other software packages).
One unaffiliated third party site that I found of value is Xtrime Printer Drivers, which includes variety of software and firmware downloads for Epson, Canon and Brother printers circa 2015-2016. You may wish to run any downloaded file through a scanner such as VirusTotal to ensure it is clean before running it). You may also find WIC Utility of interest (also unaffiliated); the free version can query many printers to detect older firmware versions and list them for review, but to actually downgrade using this software instead of manually as described in this video costs $20 per reset. Some additional firmware downgrade key combination instructions for other XP models can be reviewed here.
