HP LaserJet MFP M28-M31 on Mac; what buttons do I press for reset

[crispalomino]

I had printed earlier in the day and then had to print again and started getting printer unrecognized (approximate warning). I thought, well, I'll reset it like last time. I went to look up the directions and couldn't find them like I had before. I know that I unplugged the printer and then pressed two keys WHILE plugging in the printer and it reset fine and I was able to set up again. I had seen info on the two buttons before, but it had neglected to tell me that I had to plug it in while holding the buttons down.

Please help me, I need to print and scan documentation during this lockdown. I'm on a Mac running Mojave 10.14.6.

Thank you,

Cris

• The reset instructions are specific for your printer and performing those steps on a different printer may corrupt the device.
• I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
