HP DesignJet Z9+ 44-in PostScript Printer
Microsoft Windows 10 (64-bit)

I have a Z9+ stuck sleeping. It will not come out of sleep mode unless you unplug and plug it back in again. I have tried the front panel sleep settings and also the machine sleep settings to maximum settings. But the machine will go to sleep and not come out of sleep mode. This machine had a firmware issue on it before and  all of the fomatter and hard drive repleaced. It was setup then started having the issue of not coming out of sleep mode.
