I love the wireless/scanning/duplexing features, but am wondering if this problem is fixable.

The paper starts to feed and then never quite gets grabbed coming out of the paper tray. It doesn't jam, it just doesn't feed. When I feed manually, the printer works fine, but that is a royal pain!

I have tried cleaning all the rollers underneath - in back and front.

Other suggestions?

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?
