Akbar 0 Report post Posted August 7, 2022 @John_AdminI don’t know how to reprogram IC chips from printers main board (need sold out chips, reprogram, sold back again). Is there a program where I could trade my 7820 for a older model so I can use the easier method ? Share this post Link to post Share on other sites

Money 0 Report post Posted August 19, 2022 Looks like there is finally some headway! Will the modified binaries be available for other models such as WF7310? Or is it just for the 7820/7840? Will there be pre flashed chips available for purchase? Share this post Link to post Share on other sites

I would like to know for sure whether such firmware will be now or in the future or not, because this is the only place where at least someone promised to do it.

izlude 0 Report post Posted June 30, 2023 I came across this video of someone installing a CISS with a wf-7830, but it's European. People are asking how he rendered it chipless, he replies that the EU does not allow Epson to be rendered unusable, which I assume means it's already chipless. If that's the case, do you suppose they sell wf-7820/40 over there as well in chipless format? Would it be an option to have one imported to the US? In case I can't post links to YouTube, here's the video title: Ciss continuous ink system video for Epson WF-7840dtwf printer Share this post Link to post Share on other sites

MaryA 0 Report post Posted September 29, 2023 for 7830 we have NO chipless firmware. 7820 and 7840 only Sorry I don't know much about any of this and I feel really confused. Please excuse my ignorance at the process, I am completely new at this. Where is the chipless firmware for the WF 7820 located? All I see is the original option listed in the first post to reprogram the IC chips when I go on the list of devices and select the WF 7820. Am I looking in the wrong place? Is there chipless firmware for the WF 7820 that does not require reprogramming the IC chips? If so please include a direct link to that. I thought I had a great deal with this wide format WF but I can't afford to waste so much ink in the refillable cartridges I bought for sublimation. I also can't find replacement chips for them anywhere either. I want to set up a ciss system but it doesn't seem like thats going to happen with this model printer either. I also have a WF 2660 which also seems like it's a no go for chipless firmware. I need help or I'm going to have to buy a whole new setup I guess. Any advice is appreciated, thank you!!!
