HP M277 memory supply error

[Pierre Khoury]

Hi All,

Recently i installed third party toners for my HP M277 printer, and it seems it was updating its firmware automatically.
It keeps saying "supply memory error" for the 4 toners.
I know the solution is by downgrading the firmawre but unfortunately HP removed older firmware from it's site,
only the newest version is there for download.

Is anyone of you has encountered this same problem? and how did he solve it?

Thanks
Pierre
