Solution
bizhub C250/C252/C300/C350/C351/C450
NVRAM trouble codes (C-D3xx codes) can occur at any time. Mostly these codes happen when updating firmware. A NVRAM Data Restore procedure was
announced a few months ago to address these codes:
Stop, 0, 7, 1, 3, 9, *
What this procedure does is take a good image of the NVRAM off the MFP board (created when you performed the NVRAM Data Backup) and restore it to
the NVRAM. There are approximately 30 registers that can be corrupt, so the above procedure may have to be done as much as 30 times.
WARNING : If a corrupt NVRAM is suspected, DO NOT perform the NVRAM Data Backup. This will take the corrupt NVRAM image and back it up to the
MFP board. If this is done, and the NVRAM is replaced, the corrupt data that was just backed up will be transferred to the new NVRAM. If this is the case,
then the NVRAM and MFP board will have to be replaced as a set.
Known unrecoverable NVRAM symptoms:
1. Stuck on hourglass screen
2. Incorrect meters
3. When performing the NVRAM restore procedure the codes repeat themselves
Note : One thing that has been noticed is these machines seem to be highly susceptible to voltage sags and spikes. It is HIGHLY recommended to install a
quality power line conditioner on these machines.
Known fixes for various codes:
C-D36E and C-E002 – Install Phase 3.01 firmware (H5 or H6 depending on model).
If a corrupt NVRAM is suspected, please try performing a Data Clear. This can be found in the Tech Rep mode.
CAUTION : All programmed addresses will be cleared. Please backup the address data using PageScope Web Connection to backup the data before
performing the Data Clear. If NVRAM replacement is necessary please be aware that the meters may not be transferred and they might be reset to zero. This
is unrecoverable and the correct meters cannot be input.

Codes C-3C00 through C-3C40 indicate a corrupt BRU.
Codes C-3C50 through C-3C90 indicates a problem with the PWB-C board or the scanner to main body cable.
8050/CF5001/bizhub PRO C500
The NVRAM for the C500 cannot be replaced in the field. The only way to correct a corrupt NVRAM is to send the OACB, NVRAM, and PRCB into Konica
Minolta to be reset.
Known defective NVRAM symptoms:
1. Meters or default adjustment values are extremely high.
2. Adjustments do not hold after powering the machine OFF/ON.
Note : On the Black and White machines verify that the NVRAM is bad by swapping a good NVRAM from another machine in the same product family. This
will save significant time and expense in getting back the machine in working condition.
