I replaced the formatter and emmc board on a Managed E55040 but I can not load firmware via usb. I have tried all the tricks on the web and I have tried 3 different boards...any suggestions would be appreciated. Also can you swap these from a known good machine?

What does it mean you can't load? At what step of firmware update do you figure out you can't load firmware?

Have you tried to insert USB with the firmware when the printer is still OFF and then follow the procedure?

 

You did try with a few USB drives?

Yes I have tried different USB drives, inserting it before and after powering it on, front USB port and back USB port. If I order a hard drive, does that eliminate the emmc?

The USB light flashes when I select to download from it but then the no USB or files found message comes up. It acts like the correct firmware is not loaded but I got it from HP.

The printer should recognise USB with firmware loaded and the firmware file on it no matter eMMC or HDD. The connection from the front USB thumbdrive to the main board is OK? 

 

When you go to firmware upload you have an option for USB and USB thumbdrive. You have selected USB thumbdrive as a firmware source? 

I am 99% sure that you can't load firmware on the back USB.

Yes and I have tried 2 different formatter boards. Network and USB thumb drive are the only available options. These are the 3 firmwares i have on the USB and it does not see them.

Is there any other way to load firmware once the emmc has been formatted?  Can you swap the formatter and Emma from another printer?

From the same model yes. If you have 2 of the same model can you run firmware on 2nd printer using the same steps?
