How to Reset / Downgrade Printer Firmware?

Printer companies like Epson and HP usually release firmware updates to resolve software bugs and other problems. They are also vital in improving the overall performance of your machine. However, a firmware update becomes a major drawback if you’re using remanufactured or compatible ink cartridges.

Firmware updates are double-edged swords. It can help you fix printer issues in one hand but can restrict your use of third-party ink cartridges. And if you know how expensive ink cartridges are, it makes sense to opt for affordable generic replacements.

We have prepared a guide that you can use for any model in the Epson XP series and their compatible ink cartridges. It includes instructions for Epson XP-830 and XP-446 firmware downgrade and others. It also includes a step by step guide on how to do an HP printer firmware downgrade that applies to numerous HP OfficeJet Pro series printers.

Link your Epson printer to your computer via the USB printer cable (Type A/B printer cable). During an Epson firmware printer reset, a USB connection is needed regardless if your printer and computer are already connected through the Wi-Fi network.

Step 2

Take out all the Epson ink cartridges from their respective slots. Doing so ensures that every cartridge related error will get reset after the alternate firmware is applied.

Step 3

Turn off your Epson printer. After the device is fully turned off, complete the following steps below until the firmware update screen appears in white text.

  • For Epson XP-300 to XP-630 printers: Long press the Stop, Left Arrow, Home, and Power buttons together.

Step 4

Download the previous firmware from your computer. You may need to do some research to determine the ideal firmware as the majority of printer companies quickly take out outdated firmware from their site. They don’t provide any downgrade instructions as well. To give you a head start, here’s the name of the firmware you want to download for every Epson XP model.

After you have downloaded the firmware installer, open the file from your computer. Complete the on-screen instructions for the installation process. The previous firmware will now transfer to the Epson printer, and the machine will start flashing. You’ll have to wait for several minutes for the entire process to end. Once it’s done, however, the printer will send you a notification message on its LCD.

Step 6

After the downgrade is finalized, press OK or disconnect your printer’s power cable to turn it off then turn it back on immediately after. If prompted, install the compatible Epson ink cartridge and then allow your device to finish the ink initialization.

    Where can I download epson xp 640 firmware to downgrade. Nk19h5

    • Julia Page

      Hello Doug! I checked the Epson website and they happen to provide firmware downloads, however, these are most likely the current ones. I would suggest to Google where to download the specific version of firmware you need for downgrading and it should provide you with several options. I hope this helps!

  • Al

    Hi, XP-340.

    At step 4 I get a message ‘downgraded (it cannot be upgraded)’

    Any ideas?


    • Julia Page

      Hello Al! This process is for firmware downgrading. If you are getting a notification that it has been downgraded that would mean the process worked. Or, possibly that the version you are using is not applicable for downgrading. I would suggest verifying your current version. I hope this helps!
