If you are experiencing the Xerox error code 024-747 documented here:
Please ensure that the paper size and paper type are set correctly in the printer.
Situations that may cause this error:
Having the printer configured for Letterhead US-Letter paper only, and attempting to print.
Use the physical interface of the printer to reset at least one of the trays to support US-letter or A4 plain paper. If the paper is set to anything other than plain paper, without a PPD attached to the printer, prints will fail with the error code 024-747.
