Remove the Hard Disk Drive (if installed) and reinstall the EIO Card making sure it installed correctly by pushing it firmly inwards and checking that the two installation screws are completely tightened. Switch the printer ON again and repeat the EIO Card Test. If the EIO Card Test fails again then replace the EIO card.
2If the EIO Card Test passed 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 and repeat the EIO Card Test. If the EIO Card Test fails, then the Hard Disk Drive could be faulty. Replace the Hard Disk Drive.
3If the EIO Card Test continues to fail after replacing the EIO card or the Hard Disk Drive, then replace the Electronics Module ⇒ Page
