Troubleshooting
d. If you are using the PS driver, try using the HP-GL/2 driver instead
e. If you are using the PS driver from an Adobe application (or any other application that can
handle PS), try changing the application’s print settings so that the PS is generated as Raster.
4. Try the following Front Panel settings:
a. Change the Print Language option in the Front Panel from “Automatic” (which is the default set-
ting) to the language that is being printed (PS, HP-GL/2, …)
b. Queue = OFF
c. Start Printing = After processing
d. For PS SKUs, try changing the encoding setting (“Automatic” by default) to Binary or ASCII
5. If you are using a 3rd party application that does not print through the HP driver, try modifying the
printing workflow by:
a. Using an HP driver
b. Changing the settings in the application’s printing dialog
6. If you are using an accessory JetDirect card, try using the internal network connector or USB (if avail-
able).
7. Escalate the issue, providing the following information:
• Unit information: S/N, P/N, accessories
• Conditions where the problem occurs and conditions prior to the first occurrence of the prob-
lem.
• The result of the previous 7 steps
• The printer information pages (either printed and faxed or obtained through the Embedded
Web Server)
• The System Error detailed information (it can be obtained by pressing CANCEL + Down)
• Information on the workflow:
-Operating System
- Application
-Driver
- Settings in the driver and the application
- Settings in the printer
- Connection method and settings:
- The original file along with the information on how to reproduce the issue
- A print to file that can reproduce the issue
• The printer logs.
B. Random 79:04 during continuous printing
The error does not happen with a single job. It happens randomly during continuous printing, normally
while the printer is managing a heavy load (printing a project or in a reprographics environment).
This type of error is caused either by memory leaks or by concurrence issues in the printer’s firmware.
They normally happen in non common environments where these memory leaks or concurrence issues that
have not been detected during qualification have occurred. These issues cause the printer to crash at a
completely random moment during printing, and are not associated to a specific job.
Because of this, troubleshooting these issues is normally quite complex.
