How do you fix controller error

You can do the following

-Check the connector of the fixing film unit.
If it's ok
- Replace the fixing film unit.
Still not solved?
- Replace the power supply PCB.
Still nothing happening? Then
- Replace the engine controller PCB.

1st thing to do is upgrade the firmware. Go to hp.com and look for the software and drivers. Drill down to the firmware and read the instructions.

I have seen a corrupt print driver cause this many times test all workstations for printing then once you find the workstation that locks up the machine delete that driver and reinstall.

You can configure your HP all-in-one so that it automatically prints error and confirmation reports. If you need printed confirmation each time a fax is sent, follow these instructions before sending any faxes and select Send Only. To set automated report options from the control panel Press Setup. Press 2, and then press 1. This selects Print Report and then selects Fax Report Setup. Press to scroll through the following report types: Every Error: prints whenever there is any kind of fax error (default). Send Error: prints whenever there is a transmission error. Receive Error: prints whenever there is a receiving error. Every Fax: confirms every time a fax is sent or received. Send Only: prints every time a fax is sent indicating whether the fax was successfully sent or not. Off: does not print any error or confirmation reports. Press OK to select the report.
