Getting error code 04C300 00310000

Hi;

if you HP 1050C Plus display System Error 04CXX Try the following Steps to resolved an error:

1.)Press ENTER and switch the printer OFF. Remove the Hard Disk Drive (if installed) and make sure that the EIO card is installed
correctly by pushing it firmly inwards and checking that the two installation screws are completely tightened. Switch the printer
ON again. If this error code continues to appear then replace the EIO card.

2.)If this Error Code disappeared after removing the Hard Disk Drive, then switch the Printer OFF and reinstall the Hard Disk Drive, making sure that the two installation screws are completely tightened. Switch the Printer ON again. If this Error Code reappears, then the Hard Disk Drive could be faulty.
Replace the Hard Disk Drive.


3.)If this system error continues to appear after replacing the EIO card or the Hard Disk Drive, then replace the Electronics Module...
