Downgrade from 20201021

[IvyD]

Hi I have an HP Color LaserJet Pro MFP M2811cdw. I tried the downgrade you provide on your page but I still get the "Supply Problem" error message. I did the downgrade by USB (hotwired) instead of WIFI because that did not work either. Any suggestions?? Is there an older downgrade? Mar of 2020? Please help.

@IvyD, Welcome to the HP Support Community!

Do you get an error code with the error message?

Let us try these steps:

1.      Disconnect the printer from the NETWORK
2.      If on wired network : Unplug the  Ethernet cable from back of the printer.
3.      If on wireless network : Power of the Wireless router. Turn off the printer.
4.      Wait for 30 seconds. Turn on the printer. 
5.      If the printer is in READY state, on the printer front panel, go to Setup -> Network Setup -> Network Services -> IPv6 -> Off.
6.      Turn off the printer. Wait for 30 seconds and then turn on the printer.
7.      Once the printer is in Ready state you may go ahead and connect the printer to the network ( Power on the Wireless Router or plug in the Ethernet cable ) and then try printing.
