Epson wf 3640 update1/11/2024 Anyway, I chose not to do that (purchase a key generator), even though it might be legit, and instead used PayPal for the one-time purchase through You can dig around on the internet, and there are more than one site that sells them. (NOTE: there are other websites that purport to sell a "WIC reset key generator," and they claim that they will give you your first key for free, but each one of these sites requires you to enter all of your credit card information first - apparently in case you ever want to buy more key generating software from them? I don't know). I got a 16-digit code (key) that can only be used once. Although physically cringing when I did it, it was an easy process. Read below.įourth, (and this part sucked) as noted above, I painfully paid the $19.99 for a firmware change key for the WIC reset utility, and paid for that through PayPal. Otherwise I would gladly share my code with everyone. Unfortunately, they can only be used once. I could not figure out any other way to get a key. The painful part of this whole process is that I had to purchase a "key" for the WIC software to use in order to download that firmware. For reference, the downgraded firmware that the WIC software eventually installed on my printer was a version from Ma(version CB17J4) - I assume that was the original firmware that was installed on this printer when it was manufactured and sold new 4 years ago. In the steps below, I used the WIC Reset Utility software to downgrade the firmware version for my WF-3640 to an older version - a version that doesn't tell the printer to brick itself if non-genuine Epson cartridges are installed. That's not what I needed to do to fix my problem, but the guy in the video does a nice job walking you through the WIC software. In his video, he was attempting to permanently reset the ink levels for his cartridges. Third, I watched a YouTube video called: " Epson WF4630 Firmware Downgrade Always Full." The guy in the video is kind of rough, but he walks you through the software fairly well. Second, I installed the WIC Reset Utility on my computer. (You will see in the video - referenced below, - that the Status Monitor interferes with the process of rolling back the firmware of the printer.) After you are done with all of the steps below, you can go back and re-check the box, and the little Status Monitor icon will again appear in the task bar at the bottom of the screen.įirst step: I went to and downloaded the free WIC Reset Utility (at the time of this post, it's v.5.57) at (choose the version for your system e.g. Go into Windows Setup, Devices, Printers & Scanners, Epson 3640 Series, Manage, Printer Preferences, Maintenance (tab), Extended Settings, and uncheck the Enable EPSON Status Monitor 3 box. (The little icon that appears in the lower right of your screen on the task bar that lets you manage your print jobs). Otherwise, one of those computers might let the software sneak in and brick your printer again! Repeat this for every computer/device in your house that also has Epson Software Updater on it. (Choose the printer series, automatic updates, and change the frequency to "NEVER." Now, the only way that the firmware on my printer will ever get updated is if I do it manually - WHICH I WILL NEVER DO EVER AGAIN. I am using a PC, running Windows 10.īefore I did any of this, I went into my Epson Software Updater program (Windows Menu, Epson folder, Epson Software), and TURNED OFF automatic updating for software updates. I scoured the internet and watched way too many YouTube videos to solve this problem, but I finally did. Regardless, their apparent malfeasance has caused an immediate problem for many (if not for millions) of us. So, effectively, despite a federal law that went into effect within the last few years prohibiting printer manufacturers from forcing users from needing proprietary ink cartridges in their printers, they appear to be doing so. I also used a cleaning solution of window cleaner and rubbing alcohol (as directed in a few YouTube videos) to manually clean the printhead. I tried using the printer's "Clean Printhead" utility about 30 times (seriously), to no avail. Of course, I did not have expensive Epson cartridges installed, and my printer became useless. Apparently, it effectively prevents the printer from working if it does not have genuine Epson ink cartridges installed. For me, the firmware version that did the damage was called CB0912. Just as many other Epson printer owners experienced over the last three weeks in March 2020 (as our automatic firmware settings kicked in at different times), my Epson WorkForce 3640 (WF-3640) became obsolete ("bricked") after Epson's latest firmware update.
