dC301 NVM Initialization

Purpose
This procedure may be needed when the machine cannot recover for some unknown reasons,
including problems such as producing blank copies/prints, Xerographic CRUs not recognized,
continuously giving system fault, etc.
Prerequisites
Ensure that the following conditions are met:
• IOT software level is v7.06.3 or higher.
• The PWS is running Next Generation PWS Tool Set Release 8.1 or higher.
• The PWS is running DC 12 PWS Tools v 7.1 or higher.
• The current IOT SW Upgrade CD (Tag P39 or higher) is available.
• The customer has recorded any settings from Tools Mode, and all Auditron account data.
Procedure
1. Disconnect any Foreign Interface devices. Disregard the FI fault codes that will be
declared at power-up.
2. Obtain the following data:
• NVM Value Factory Setting Report (typically it is located in the Tray 1 pocket).
• Any setting changes (specifically NVM settings) shown on the machine's service log.
• Any previously-saved machine NVM data on floppy disk.
3. Enter the Service Diagnostics Mode. Refer to
using the PWS.
4. Go to dC371 Configuration Page. Verify the machine configuration. Correct any errors
before continuing.
5. Go to dC351 NVM Background Processing. Select Save Machine Settings to save
NVM data. If the process is successful, proceed to step 7. If the NVM data was not saved
correctly, continue with step 6.
NOTE: You may be unable to read or save NVM values using the PWS Diagnostics Tool due
to either a failed IOT CPU PWB or a failed NVM PWB. If you were sent here by the IOT PWB
replacement procedure, it may be possible to save NVM after the PWB is replaced.
If the NVM PWB has failed you will be required to re-enter the values from the Factory NVM
Settings or from a previous floppy disk database, and any other NVM changes retrieved in Ini-
tial Actions. You may need to perform setup and alignment procedures after initialization.
6. Go to dC131 NVM R/W. Record the values for the following locations:
• 749-030 Fault detection
• 759-053 Print ESS data
• 759-054 Scan ESS data
• 771-138 IBT Cleaner retract start time
• 772-017 Fuser Fan fail detection
• 773-004 Target Density switch
• 775-731 ATC Enable
• 775-750 ATC Calibration successful
• 775-815 TC set average
• 775-851 ADC change by ATC (Y)
