Well, Bad luck,
The printer initialized the cartridges(all of them new full), then all of the print heads, then it spent 40 minutes initializing the print system, then it asked for paper to align the printheads, and then it froze, unresponsive to any menu buttons.
So I powered it off and on, 3 times now, each time the
1 - the panel lights up but blank
2 - there is a single beep
3 - there is a 4 second pause, and then 8 loud beeps spaced apart.
4 - there is nothing on the panel except the white light, no boot started.
I pulled the formatter card, pull the battery, let it set for 30 minutes, put it back, same 8 beeps.
I can't find a Z3200 BIOS beep explanation
