Enable/Disable Log Files
The network controller process/state log files are permanently enabled. The following logs can
be enabled or disabled, as a group, using the PWS:
Enabling these logs will degrade machine performance.
• NC Debug Logs.
• Event Log.
• Shutdown Log.
• Error / Warning Log.
• Completed Job Log.
NOTE: It is not necessary to keep the PWS connected if selectable logging is enabled.
NVM Save and Restore
NVM Save and Restore is used to save NVM settings to the PWS, then restore them to the
machine. Previous NVM values can be restored after loading a software set using AltBoot, or if
the machines NVM settings are changed.
NOTE: If the machines NVM has become corrupt, the most recent Golden NVB Restore file
will be required. The file is available from Office Black & White and ColorQube GSN library,
number 10231.
NOTE: From PWS Tools version 130.00.0006 onwards. The NVM Save and Restore tool has
the option to perform the dC132 NVM Initialization, All Copier NVM routine.
When the machine software is upgraded using AltBoot, customer NVM settings are not auto-
matically saved. The customer NVM settings must be saved, then restored using NVM Save
and Restore.
Procedure
1. Important - Connect the USB cable between the PWS and the machine before opening
the NVM tool.
2. Ensure that the PWS is connected to a mains AC power supply.
3. Open the NVM Save and Restore application on the PWS. Follow the instructions.
If the PWS suffers a power failure or crash during the procedure, the machine should recover.
If the machine has not recovered after 5 minutes, perform the following:
1. Switch on the PWS. Open the NVM Save and Restore application on the PWS.
2. Select the Exit button in the NVM Save and Restore window.
3. Restart the NVM Save and Restore procedure.
4. Set the USB connection mode to Walk Up USB Printing, refer to

GP 6 Screw Usage
Purpose
To prevent damage to parts that may be damaged by screws not being installed correctly.
Procedure
Replacing Existing Screws
Always use the correct driver for the type of screw head. Use a nut driver if possible; this gives
a better grip than a slotted or cross-head driver.
Take care not to install self-tapping screws into machine-screw holes, or machine-screws into
self-tapper holes.
When replacing self-tapping screws into plastic components, turn the screw counterclockwise
to engage the original thread, then turn the screw clockwise. Do not overtighten. If a new
thread is cut, the plastic component will lose the ability to hold the screw as firmly, and eventu-
ally not at all. This also applies, to a lesser degree, to metal components.
NOTE: Reverse the direction of turn for left-hand threads.
Use the same method for machine thread screws and nuts to avoid cross threading.
Inserting a Screw into an Un-threaded Hole
Some new components are supplied with fastening holes that do not have the screw thread
pre-cut. It is the insertion of the first screw into the hole that forms the thread.
Use the following procedure to avoid broken screws and damaged holes:
1. Ensure that the screw is a thread forming screw, refer to
