I have a PageWide Pro MFP 57750dw and whenever we power it on, the LCD displays the HP logo for a few seconds and then changes to a blue screen with a Power symbol on it and the error code 0112E9AA. I've powered the thing on and off, disconnected the power, opened and closed every door I can find, and pulled out the different toner cartridges and put them back. Nothing I've tried has got the error to go away. I also have had no luck finding this error code anywhere on the internet either.
