      If it is printed out of Corel, convert it to pdf and try again.

            Hi

            I have the same fault on a C280 my next step is to return on Monday with a Laser (print) unit and try that.
            Unfortunatly it's very intermittent but will let you know if it works.

              Hi Rinser

              I don't know if you had any luck with your fault but i tracked mine to be the MFP board.
              Regards.
