Hi,
I share a informative link please visit and read it.... HP Support document HP Support Center and HP Printer Support

Thanks,

HP Service Manual Library

Download the manual here, this is your best option and will show you step by step.

If you are unable to solve this problem using above mention solutions then you can try this one. Open all covers and then detach the DC controller board that is shown In picture below. it is the back side of DC controller board.


With this DC controller board you can see another small circuit bard that is attached with DC controller board with a white (ribbon) cable. I found two printers with this error when I examine the board I found that the thin print wires are broken as shown in the following picture. I have to connect these wires with soldering and now it is working fine.




If these printed wires are ok then you can check the ribbon cable .check all connectivity with Multimeter.
First you solve this problem with software.
Then try to find disconnected wires or dry soldering on circuit board.
Last you change the Dc controller board because the problem is in surly in DC controller board.

Remove formatter assm, remove back cover you can see above snap shot of dc board, discnnect all the connectors gently, remove screws take it out...Replace another one.. But you are not mentioned why you are going to replacing the DC controller..

I have had this problem before and replacing the high voltage board ( that is the large board situated under the printer ) fixed it. However if you have replaced this board then I would agree that the water also took out the DC Controller Board.
The fuser probably did not need to be replaced.

this error could be caused by the new replacement fuser or your DC controller board. I would return the fuser that you just put in for another first. And if the issue is still there then try a new DC controller board.
