However, there are some workarounds and short-term solutions that can be tried in order to get the
customer up and running in the shortest possible time.
1. Send the job using a variety of different settings. The issue is often caused by a combination of the
job contents combined with some specific setting(s).
2. If the customer is sending the file directly to the printer, try using the HP driver instead.
3. If the issue occurs when printing through the HP PostScript driver from an application with PS
passthrough, try changing the options in the application so that it prints PS as raster (the option is
typically located in the Advanced options of the application’s printing dialog).
Data-related SE 79:04
The printer has a hard disk and non-volatile memory that contain databases and files that can be
modified by the customer. Some examples include:
●
The printer’s queue
●
The hard-disk partitions that contain the customer's jobs
●
The database that stores printer settings
●
The database that stores accounting information
Some of these data are accessed by the printer at start-up time, and some others are accessed as
needed.
If any of these fields contain corrupt data or data with characters or values that cannot be correctly
processed by the printer, a 79:04 system error may occur.
Cause
There are two different types of symptoms for data-related 79:04 system errors.
1. When the corrupt data are accessed during start up:
a. The printer will display a 79:04 during the start-up process
b. Switching the printer off and on again will not solve the issue. The printer will continue
displaying the 79:04 system error until the corrupt data have been cleared through a service
procedure.
2. When the corrupt data are accessed during normal printer operation:
a. The printer will start up normally.
b. When the data are accessed (for example while printing, while navigating the queue or
when changing some settings), the printer displays a 79:04 system error.
c. The printer can restart normally.
d. When the data are accessed again (typically, under the same conditions as in step b), the
79:04 system error is displayed again.
Solution
Data-related 79:04 errors are often resolved by means of hardware intervention. Since data are stored
in physical components (RAM, EEROM and hard disk), replacing these components with new ones that
