work force pro printer 4630: Problem downgrading the firmware of an Epson WF-7840

Thu, 09 Jul 2026 04:38:33 -0700

Good morning everyone,

I've had the bad idea to upgrade the firmware of our Epson WF-7840 (version CD17M6 now).

Now, our non epson cartridges are not recognised anymore.

I've search the web about how to downgrade the firmware. I found the procedure, found how to put the printer in "recovery mode" and, on the Epson website, I found the "Recovery Mode Firmware version CB08LC" for the Epson WF-7840.

But it doesn't work...

First problem, the model of the printer does not appear in the "Epson firmware updater" but it sees that a printer is connected.

Second problem, and it is where it stops, when I launch the Update, it fails with a message on the printer's screen "Data file not found".

I tried with my mac (macbook pro 16" m1 max) and with an older macbook pro from 2009 with the same result. I tried with another USB cable and still no luck.

What am I doing wrong?

Epson WF-2540: Why is the printer not turning on?

Wed, 08 Jul 2026 15:14:59 -0700

I bought this printer last year and never touched it or took it out of the box until now. The printer is brand new. I set up the internet connection without any problem. However, I started printing and all of a sudden, the printer turned off by itself. I tried turning it back on but would not turn on. I even tried changing plugs to see if the plug is the problem. What can I do to fix this printer?

Epson Printer: Epson cs-t2100 driver does not recognize roll width

Wed, 08 Jul 2026 02:36:11 -0700

I insert a 450mm roll into the SC-T2100 plotter and the plotter recognizes it with that width. When I want to print, the drivers do not recognize that width, but set 432mm as the closest smaller width from the list in the roll paper width field and lock that field. Can that list be supplemented with a width of 450mm or possibly change some of the existing values.

Epson WF-3640: Epson WF-3640 paper jam message, spring and gear fell out

Tue, 07 Jul 2026 01:34:01 -0700

I queued way too many papers for my printer to handle and it got jammed. I had no idea I can open up the back side to remove it so I opened the scanner unit and forcefully pulled out the paper from under the roller, so I think I broke something.

I found a small gear that came out but I reattached it ( red circle ) but there's also a spring that I have no idea where it came from. Check it attached photo, you can see the spring right there
