John_Admin 390 Report post Posted January 8, 2019 You know - if You want to change (update/downgrade) firmware in Your printer - You can do it in 2 ways: - in regular mode (requires OEM ink cartridges installed and had be NO errors in printer) - in Program Update Mode ( can be performed without ink cartridges at all) So here are 2 ways to put WF-2860, WF3720 Series printers in Program Update Mode: 1. Power OFF the printer. 2. Press touch screen Place A + Power button. 3. Hold them - 20 seconds!! until Blue Power Led is ON. 4. Release all. Printer is in Program Update Mode now. If Touch Screen Place A doesnt work (printer just switches ON in regular mode) - You have to use touch screen Place B: Please watch here how to put WF-3720 printer in Program Update mode (Place : P.S. When You press Touch Screen and Power button - the Power Led has to be OFF for about 20 seconds. If It will start to flash in 2-5 seconds after you press - that means You have used wrong place to press on touch screen. Try other way. Share this post Link to post Share on other sites

PonPon 0 Report post Posted November 18, 2022 Hi John, my EPSON WF-2860 is now in program update mode. What do I do next? I updated the firmware to the latest version 2 days ago, and now the screen shows Maintenance Error, not recognizing 3 of the 4 cartridges. These are remanufactured ink cartridges. The black one is also remanufactured by EZInk, but that one is ok. Now I can't turn on my printer at all. It's stuck on the Program Update mode. Please help! PS: I unplugged the printer. When I turned it back on, it just went to the Maintenance Error screen and I'm stuck there again. I was able to find an older version of firmware for WF2860, but I don't know how to install it on my printer. I'd appreciate some advice or tips if you can share. Thank you!
