Product: Laserjet Pro M404n
Operating System: Microsoft Windows 10 (64-bit)

Have a Laserjet Pro M404n printer that worked fine for a period of a few months but now all it shows during power up is MFG MODE on the display.  The funny thing is when I connect the printer to ethernet it grabs an IP and I can navagate the embedded web of the device, but anytime I try to send it a reboot command or reset to defaults, it returns a "Printer busy, Try again later" message.  So the printer is somewhat working.

 

Is there any keys I can hold down to get this printer out of MFG MODE.  The firmware is the latest build.

 

Thanks again,

Jamie

I am having the same issue on one of my customers M404, replaced mainboard that I previously had for testing purposes didn't help, now I am waiting for a new DC controller board.

If you manage to get your running normally again please let me know, will let you how it went after DC board replacement within a few days.

After replacing the DC controller board, first power up same issue MFG MODE.

Turned the printer OFF it went to Ready instead of turning off, I run one cold reset and it's working fine now.
