Xerox 4050 Service Manual

The procedures in this chapter describe powering off your LPS.

The system has a power saver feature designed to save energy
and to reduce wear on moving parts.  You only need to power
off the system when it will be idle for 8 hours or more.

Depending on whether your system is receiving jobs from an
offline source or an online source, follow one of the procedures
described in this section to power off your system.

Follow these steps to power off the LPS if your system is
receiving jobs from an online source:

1. Contact the host system operator and request that the

output from the host to the LPS be drained and the system
be varied offline from the host.

2. Press <JOBS STATUS> to determine if the system is idle.

If the queue has no jobs waiting to print, the following
message displays on the controller:

JOB QUEUE IS EMPTY

If the job queue is not empty, enter the ENDJOB or the
DRAIN command to print any pages remaining in the print
file.  Then press <JOBS STATUS> again to verify the queue
is empty.

3. Enter OFFLINE.

4. Enter CONTINUE I or press <CON>.

CAUTION:  Failure to have the system offline prior to
powering off causes problems with the host system.

When the following message appears, press the System
Power Off button:  

OS0040 System is 'OFF-LINE'
