Maggy 0 Posted December 1, 2020 Hi, 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...

Admin 3 Posted April 6 Hello! 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

Murphs.World@verizon.net 0 Posted Tuesday at 10:30 PM Hi, I was correct in that the printer could NOT be updated due to the non-Epson print cartridges were still in the printer, (and thus Epson was complaining). Once I purchased Epson cartridges, the process began as one would expect! Problem now is, per directions above, the update did NOT get stuck between 70/80%, instead the update ran till about 98% and then complained it had not been successful?? Please assist!!
