Maggy 0 Posted December 2, 2020 Hi, I might have posted this question in the wrong topic earlier. I'm reposting it here. When opening the pdf file with the instructions for the Work Force 2850, I got this file: "Instructions for updating the printer firmware in chipless, method 9 Compatible Epson Printer Models: WF-2630; WF-2631; WF-2650; WF-2651; WF-2750; WF-2751; WF-4630; WF5620; PX-M840F" NO 2850 mentioned... How do I enter firmware mode for the Epson WF-2850? Thank you for your help. Quote Share this post Link to post Share on other sites

Admin 3 Posted January 24 Hi! Please try this new file for you. https://inkchip.net/download/INKCHIP.net_Firmware_99_WF2850_v1.rar 1) Upload firmware which I sent 2) Switch on in normal mode(!!!!) just turn on button . - dont put printer in Program Update mode. (no need to press few buttons while turn on the printer) The uploading process will stuck at 70-80% - it is ok! Open task manager and stop updater process. Printer will blink for about 5-15 minutes - then will power OFF. Now power on the printer - chipless firmware is installed in your printer! Quote Share this post Link to post Share on other sites
