I had a problem with my CM 2320 fxi MFP, I couldn't use the scan to email.
Anyway, I tried to update the firmware + to reset the all printer.
But when I updated it, using the HP software with my Mac, the process stopped during "Erasing".
Then, using a Windows 7 64bits, I tried to replace the firmware (with that link https://support.hp.com/ph-en/document/c02675055)
Everything was okay, except a the step 9 (Click the check box next to USB001. If USB001 is already connected to another USB device, click USBXXX where “XXX” is the highest-numbered USB device that has a description of Virtual printer port for USB. Using the scroll bars on the right side of the window might be necessary, depending on the number of devices installed.), I couldn't find that check box
So I created a new printer, linked to Virtual USB 0002, named "hp hp"
With HP LaserJet Firmware Update Utility, I sent the firmware to the printer "hp hp"
After that, on the printer screen "donwloading" appears, then "erasing"
And now it is blocked on "erasing" for 30 minutes, and it's not moving
Do you have an idea how to rescue my printer that I love so much ?
Thanks for your help
