Random 79:04 during continuous printing

The error does not happen with a single job. It happens randomly during

continuou

s 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 p

rinter’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.

1 R

eboot the printer twice (after the first reboot, the printer will show the 79:04

ystem error again, since the printer will attempt to reprint the last job in the

queue. If the issue continues occurring randomly, continue troubleshooting

2 If y

ou are using an HP driver, update the driver to the latest version

3 Upgrade the printer’s firmware. Even if the c

urrently installed firmware

version is the latest one, re-install it.

4 Try the following changes in the workflow:

a Change the Print Language option in the Front Panel from “Automatic”

(

which is the default setting) to the language that is being printed (PS, HP-

GL/2, …)

b Que

ue = OFF

c Start Printing = After processing

d For PS SKUs, try changing the encoding setting (“Automatic” by default)

o Binary or ASCII
