Suddenly printer displays that error code on startup.
Saying to reboot or call HP.
I disconnected cable, no avail.
Printer has been completely revised/overhauled by HP in 2014 : new motherboard, new printing cart, new belt, new printing heads and even some other parts have been changed anew.
Is that printer particularly quirky ?
It has seen moderate usage and have always been on to let cleaning processus operate.
Please refer to the bottom of this page:
http://z3200.com/HP-Z3200_Printers-HOW-T0s.htmAlso, when you pull the formatter board to replace the battery (and I'll bet it wasn't replaced at the time the printer was overhauled), be sure to keep the unit unplugged for over an hour to allow capacitors, etc., to discharge and static charges to dissipate. HP refers to this as resetting the printer. It has been my experience that the longer you wait, the better the chances of dissapation, hence more likelihood of success.
Unplug printer.
Push start switch to off position
Pull the formatter board (just two hand screws - you may need a small flathead screw driver) pull straight up.
Blow off the formatter board with some canned air or a bulb.
Replace the battery.
Be sure to wait minimally 1 hour before putting the board back in.
Test the wall outlet to be sure it is working correctly.
Plug the printer in.
Turn the printer on via the "on" button/switch.
The printer should eventually display a message "FSCK" (file system check).
Allow the printer to initialize and it could take an hour or more.
If nothing happens, unplug again, pull the formatter board, lift the battery out, wait 5 seconds and put it back in then replace the board, make sure switch is set to off, then plug back in.
See if it will initialize.
If you don't see anything happening, then it's on to the next phase of trouble shooting.
Good luck.
