My printer is coming up with ! please help it is not printing
Hi sales233:
Here is your problem.
Engine error. The formatter
and engine are not
communicating.
1. Unplug the printer, and
then plug it in again.
2. Reseat the formatter
cable in the ECU.
3. If the error persists,
replace the formatter.
4. If, after replacing the
formatter, the error
persists, replace the ECU.
ECU: is the Engine Controll Unit
A certified HP technician will have to work on this machine.
Hope this helps.
