'Firmware Corrupt Ready 2 Download' Error. From reading other comments, it appears that I need someone from support to send me the steps to perform an NVRAM reset in a private message, as they did here. https://h30434.www3.hp.com/t5/Printer-Software-and-Drivers/MFP-M277dw-Ready-2-Download-fw-is-corrupt...

Google and download HP LaserJet M2727 mfp Service Manual then NVRAM is inside.
if after NVRAM it's still no work then you need to try to resend firmware through USB cable, if you can't see any firmware updating processing on the panel you'll need to change the connect port from USB001 to USB002 003 004...... one by one until one of them will work and you can see the difference on the panel. The connected port is in the printer property by right clicking the printer icon.
If after succeeding firmware updating and reboot M2727 you still get the 'Firmware Corrupt Ready 2 Download' Error then you need to change the formatter.

Thanks East2100. The NVRAM instructions didn't work initially, but I was eventually able to resend the firmware through USB by trying multiple USB ports and selecting the HP universal print pcl6 device instead of the M2727nf pcl6 device. After the firmware was reinstalled, I did a NVRAM reset and it worked fine. Problem is, I clearly have a bad formatter. The unit reboots regulary and often gets stuck in the initiating mode.

Then you can try the baking method it'll often work for one or two year longer or shorter but it should work for the first time.
What my experoence is it'll become shorter and shorter when you bake the formatter more than once and one it'll never work anymore. But maybe don't have to worry so much as long as it can last its life.
In the end you'll have to replace the formatter but who cares by now.
Google "HP M2727 bake" you'll find out many of them. Hope it helps.

East2100 - Thanks again. I waited until the printer stopped working completely and baked the formatter. It's been working perfectly for a few months now. Since the printer is 10.5 years old, I consider any additional life as gravy, but hopefully I will get a year or two more out of it.
