I see you entered this question in some time ago?  Did you ever get a resolve?  I dont see any wise words of wisdom coming from the Site Admins?  I just ran across the 8:04 issue this week and am a little stumped as to what to do?

One of the main questions asked by HP tech (LOL) support is ...is the plotter plugged into a wall plug. Otherwise, we have this problem with another customer Laser printer, and downloading firmware to a zip drive, the plugging it into the control panel as its starting.

After the firmware (HP has a big problem with its software, no surprise, for years) installed, jobs from two days ago, started to print out.

try simple first.

New technology (touch screen) is cute..but buttons work better!

Its up to us field techs to correct HP screw ups! Thats what I get paid for. As mentioned: they have had a BIG problem with their software. So whoever designs the software, should flogged or fired! As Trump famous: YOUR FIRED!
