Thank you very much and Appreciate your help and support.
Unplug the printer from any data connections (network or USB) and then turn the printer on. If it successfully boots, it is a corrupted print job issue.
If it did not solve the issue, following this procedure from the service manual will clear the error:
1. Clear all information that has been introduced by the customer using the standard tools available in the printer.
a. Delete all jobs from the queue (from the front panel or the Embedded Web Server).
b. Reset to factory defaults to clear the customer’s configurations and calibrations.
c. Delete any non-standard paper presets in the printer (both the ones that have been created by the user and the ones that have been installed as OMES profiles through the Embedded Web Server or the HP Utility).
2. If step 1 did not resolve the issue, you can use Service Tools to clear additional information that could be causing the issue.
a. Start the printer in Diagnostics Boot Mode.
b. Perform an EEROM reset.
3. If step 2 did not resolve the issue, it is possible to clear all the information on the hard disk and the different EEROMs, leaving them as they were when the printer was new.
a. Access the Service Utilities Menu.
b. In the Secure Disk Wipe menu, set the Sanitize level to Insecure mode.
c. Execute the disk wipe. This will clear all partitions on the hard disk that contain customer data, including the partition in which the operating system is installed. After the disk wipe has completed, a backup firmware version will automatically be installed from a backup partition to allow the printer to start up. This backup firmware is a very old version.
d. The firmware in the printer should be updated to the latest official version as soon as the printer has restarted.
After step “c”, any 79:04 which is caused by corrupt data in the printer will be solved.
