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 5 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

BWeir 0 Posted March 21 I just bought the firmware to have a chip less ink cartridge system in my printer. I have downloaded all the necessary items that were Included but when trying to open the firmware, there is nothing that is coming up. I also clicked on instructions for my printer and it is showing instructions for a different printer. So I’m not sure how to get into the firmware mode. Any help is appreciated!

BWeir 0 Posted March 22 So I downloaded what you sent. It still says could not find files to start. I even turned off my firewall on my computer and made sure my computer was completely up to date. Nothing is working. Quote Share this post Link to post Share on other sites

rdy 0 Posted April 6 Hello I used winzip to open firmware_99 file as per link above. The printer turned off and on around 80 ish % after that a message showed the process update failed. I stopped it using task manager. My printer WF 2850 now shows firmware BL05K3 Is this correct? I have not tried to use my activation code yet? Quote Share this post Link to post Share on other sites

Murphs.World@verizon.net 0 Posted April 10 (edited) Has anyone gotten this process to successfully complete? Mine states "The firmware update printer could not be updated": I wonder if the issue is that I am NOT currently using EPSON Ink, so the printer is still attempting to use the Non-Epson Ink I previously had installed? Perhaps this is the "Ensure that the printer is not middle of the setup."? Please help! Edited April 10 by Murphs.World@verizon.net Quote Share this post Link to post Share on other sites
Admin 5 Posted April 14 Your original firmware cannot be downgraded to earlier versions, and our chipless firmware is an earlier version. Basic concepts of the solution: - Standard InkChip firmware. Chipless firmware, which must be loaded into the printer using Firmware Mode. - 99 InkChip firmware. Chipless firmware, which must be loaded into Normal Mode. - Firmware Mode - special mode for updating printer firmware, which is activated when a certain buttons combination is pressed. - Normal Mode - normal mode of operation of the printer, simple switching on the printer with the power button. Algorithm for solving the problem: 1. Check and memorize the firmware version of the printer. The firmware version displayed is the original non-update version. 2. Flash printer 99 with InkChip firmware in Firmware Mode. 3. When trying to activate the firmware with the Activation program and the activation code, the program will generate the Reading failed 1. 4. Start flashing the printer 99 again with InkChip firmware in Firmware Mode. When the firmware status in Firmware Mode reaches 100%, and the printer display finishes counting the percentage of the firmware status, you need to pull out the power cable of the printer. 5. Connect the power cable and turn on the printer. Recovery Mode will appear on the display. 6. Flash the printer with Inkchip firmware in Recovery Mode. 7. Check the firmware version of the printer. The firmware version displayed must be different from the non-renewable firmware version. This version is the chipless firmware version of InkChip. 8. Activate chipless firmware with the Activation program. https://inkchip.net/download/INKCHIP.net_Firmware_99_WF2850_v1.rar This is just an example of a process, it doesn't matter what model of printer you have. Please watch the video on our official YouTube channel: https://www.youtube.com/watch?v=h7qWYWjMNFQ And after that just ran again the inkchip firmware upload in normal mode.

Murphs.World@verizon.net 0 Posted April 15 Thank You very much for replying!! Seeing as the revised executable and suggested steps above did not work; I decided to attempt with the Original code and instructions posted on the https://inkchip.net/soft/ page: NewWF-2850, WF-2851, WF-2855 Watch Download Download Download I followed the provided instructions from the web page INKCHIP_Instruction_WF4630.pdf; Which really didn't speak specifically to my printer in the instructions so I kind of made my own. For STEP 4. Enter the printer in firmware mode; I took the updated directions above applicable for the WF-2850 family and initiated the update from a normal startup. This worked because I did have Epson cartridges installed, so I was no longer receiving the invalid cartridge error once it started up, so I had a normal startup. I then initiated the INKCHIP.net_Firmware_WF2850.exe at Step 5 rather than stalling at 70 / 80%, the update ran to a clean end of job! I did see the “FINISHED” on the display, however there was no flickering or anything else, it displayed it's normal printer status window. After about five minutes I simply shut the printer down. Following again the INKCHIP_Instruction_WF4630.pdf instructions provided from the web page at Step 6 through Step 10 there were no differences! I hope these instructions might assist someone else with similar issues to what I had run into. I am a VERY HAPPY InkChip.Net customer 😉 Thanks again for all your input!

sdubgold 0 Posted April 30 Just an FYI for anyone who comes across this. I was having trouble and this is what worked for me: First, I couldn't get my printer into recover mode with the button code given. I don't think it works for the 2850. So, I just decided to try to run the program in normal mode as suggested above. I ran the .exe that I downloaded from the website, but when I got to step 4 where you select your printer it said "downgraded (unable to update)" under status. I downloaded the firmware_99 file from this chain, and when I got to step 4 I had no problem! I ran the firmware update and when it was around 80% or so my printer restarted. Then the firmware updater popped up with the error that the firmware could not be updated. DON'T WORRY ABOUT THAT ERROR MESSAGE. Even though it says that, the firmware has in fact been updated. I just checked the version on my machine and it says "BL05K3". I have not purchased the key yet to try it out with the chipless cartriges but it looks like it worked fine. Thanks to the admin for all the detailed instructions. It's highly appreciated! Quote Share this post Link to post Share on other sites
SPublishing 0 Posted June 26 My Epson Wf-2850 Firmware shows the BLK05K3, however the Inkchip Firmware on my computer will not show that the firmware is on my printer and will not allow me to complete step 7 of the firmware update process. Since I cannot finish this process, I cannot activate the chipless firmware. I had to install the firmware in recovery mode, as the normal USB process failed every time. Please tell me how to get the firmware screen to recognize the firmware that is on my printer so I can activate. Thank you Quote Share this post Link to post Share on other sites
