bec

ause its in an incorrect format, rebooting twice will clear the error (the

first time after reboot, the printer will attempt to print the job again, and this

will cause the error to re-appear). If rebooting the printer twice solves the

issue, then it is an issue related to the job and you should refer to page 2,

process will be needed. For more information, see
