HP T1100 Error 79:04, upgrading firmware

Can someone please help, please!

 

How do I upgrade the firmware on T1100 printer while in Diagnostics Boot Mode. The printer as a 79:04 error on startup.

 

Found this on the hp forum

 

"booting the printer in Diagnostics Boot Mode.

For this, a special file and a special upgrade process will be needed. You can find the specific information for the printer model you are troubleshooting on page 13: Appendix A in the attached White Paper."

 

Can anyone point me in the direction of this white paper.

 

 

Thank you

You would have to contact HP directly in order to get a plt version of the firmware to complete that process.  Typically that error code means either your hard drive or formatter card has failed.  The firmware comes on the new hard drive, you have to use an HP hard drive, a blank one will not work.  The earlier versions of the formatter card used EIDE connections and were known to have issues, HP modified the formatter to use SATA connections and they work much better.
