GP 4 Machine Software
Purpose
To provide machine software information and to show how to load software.
Description
Software sets are compilations of the various software modules and together with a SCD (soft-
ware compatibility database) are bundled into a DLM or UGD file available on a CD. There are
four methods of upgrading the machine software. Refer to Software Loading Procedure.
Refer to the following items for additional information about machine software:
• Modules
• Software Compatibility Database (SCD)
• Common Upgrade Behaviour
• Software Loading Procedure
• Software Loading Progress
Modules
A software module is defined as a programmable piece of software existing as a file in its own
right. Software modules reside on hardware modules.
The following hardware modules contain firmware and cannot have software upgrades loaded:
• Scanner.
• Paper feed module.
• High capacity feeder.
NOTE: The software for the scanner, paper feed module or high capacity feeder can only
be upgraded by installing a newer version of the relevant PWB on each hardware module.
Software Compatibility Database (SCD)
The SCD is used to describe the machine system software. The SCD comprises of the system
software version, in the format WW.XXX.YY.ZZZ and a list of software versions for the different
modules. It can be described as follows:
• W - is the platform, for example;
– 20.xxx.yy.zzz = WC
– 21.xx.yyy.zzz = WC + Postscript
• XXX - is the field for major changes.
• YY - is the field for minor changes.
• ZZZ - is for spar fixes.
NOTE: The system software version is displayed on the UI under Machine Details.
The primary function of an SCD is to ensure that all software on the machine is compatible.
Common Upgrade Behaviour
A software upgrade is requested if a new hardware module is installed which has an earlier or
later software version.
When an upgrade has been initiated the machine will reboot with all modules in upgrade mode.
General Procedures & Information
GP 4
Progress and errors are displayed on the GUI screen (and on the PWS software upgrade tool
screen, if this is used).
When the upgrade is complete, the machine will reboot.
When a machine without a network controller is switched on, the image processor compares
its SCD with the software in the hardware modules. If the software is not compatible, the image
processor requests a software upgrade. The fax and output module is upgraded from the
image processor. The other modules require the PWS tool.
When a network controller is fitted, the software in each hardware module is checked, at star-
tup, from the SCD on the network controller. If necessary, a software upgrade or downgrade is
instigated by the network controller.
NOTE: If a component is installed that has a later version of software than the software set on
the network controller, at machine startup the software on the new component is downgraded.
The SCD is updated on successful completion of the upgrade.
Software Loading Procedure
Initial Requirements
• Before software is loaded, ensure that the machine is in a fully operational condition. Any
active faults or jams must be resolved before starting this procedure.
NOTE: The procedure will take approximately 30 minutes.
• If the software loading procedure fails, go to OF5 Boot Up Failure RAP.
• After the software is loaded, perform GP 19.
Refer to the software loading options:
• Software Loading onto Copiers
• Software Loading Via the Customers Network
• Software Loading From the PWS
• Software Loading Using AltBoot
• Software Loading Progress
Procedure
Copiers (Non Networked Machines)
There is one method to load software on to machines that are not networked. The software is
bundled in a UGD file. Refer to Software Loading onto Copiers.
Copier / Printers (Networked Machines)
There are three methods to load software onto networked machines:
1. Use the customers network. The software is bundled in a DLM file. Refer to Software
Loading Via the Customers Network.
2. Use a PWS to download the software from a CD or the PWS hard disk drive to the
machine. The software is bundled in a DLM file. Refer to Software Loading From the
PWS.
