Restore The Printer To Operation

illuminated and the printer
appears to be working, but
nothing prints and “Invalid
Data” displays. This message informs the user that the printer has received
data, but no valid commands were found. This typically occurs
when an incorrect emulation or SFCC was selected. This
message will continue to display until new data is received or
when the printer is put offline.
1. If the emulation and SFCC are correct, additional
diagnostic information can be obtained by selecting the
desired option under the “xxx Diagnostics” menu, found
under the Emulations menu.
2. Afer selecting the desired option, rerun the job to obtain
the additional diagnostic information.

PAUSE key, and if a fault message displays, refer to the
LCD Message Troubleshooting table on page 305.
