Product: LaserJet MFP M577
Operating System: Microsoft Windows 10 (64-bit)
Hi,
I bought a used Laserjet MFP M577. I figured out that there is no HDD and no DIMM installed. I will buy a HDD and DIMM and install them. But also there is a password which I don't have. The only thing I can see currently is a small menu and the few function available do need a password.
How I can reset the device?
In which format should I preformat the HDD (NTFS, exFAT) ?
Which DIMM do I need (DDR3) ?
