SC195 (Machine serial number error) will be displayed if you forget to attach the NVRAM.
If you mounted the NVRAM in the wrong direction, it will cause a short circuit in the controller board and the NVRAM, and each component will need to be replaced.
Installing a new NVRAM initializes SPs and issues an SC. Reset the SC with the procedure below.
Make sure that you have the SMC report (Factory SP Settings). This report comes with the machine. (SMC Storage
)
If you do not have the SMC report, enter the factory settings while referring to the "Factory SP Settings" (Factory SP Settings).
Output the SMC log using one of the following methods:
To print SMC log data, execute SP5-990-001.
To save SMC log data to an SD card, execute SP5-992-001 (SMC List Card Save Function).
Turn OFF the main power.
Insert a blank SD card in the SD Card Slot 2, and then turn ON the main power.
Use SP5-824-001 to upload the NVRAM data from the controller board.
Make sure the customer has a backup of their address book data. If not, obtain the backup by referring to SP5-846-051.
The address data stored in the machine will be discarded later during this procedure. So be sure to obtain a backup of the customer’s address book data.
Note that the counters for the user will be reset when doing the backup/restore of the address book data.
If the customer have a backup of the address book data, use their own backup data for restoring. This is because there is a risk that the data cannot be backed up properly depending on the NVRAM's condition.
For MP 501/601, do the following steps.
Print the Box List with the User Tools.
[User Tools] -> [Machine Features] -> [Facsimile Features] -> [General Settings] -> [Box Setting: Print List]
Print the Special Sender List by pressing these buttons in the following order.
[User Tools] -> [Machine Features] -> [Reception Settings] -> [Program Special Sender: Print List]
Write down the following fax settings.
[Receiver] in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Reception Settings] -> [Reception File Settings] -> [Forwarding].
[Notify Destination] in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Reception Settings] -> [Reception File Settings] -> [Store].
[Specify User] in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Reception Settings] -> [Stored Reception File User Setting].
[Notify Destination] in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Reception Settings] -> [Folder Transfer Result Report].
Specified folder in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Send Settings] -> [Backup File TX Setting].
[Receiver] in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Reception Settings] -> [Reception File Settings] -> [Output Mode Switch Timer].
[Store: Notify Destination] in [User Tools] -> [Machine Features] -> [Facsimile Features] -> [Reception Settings] -> [Output Mode Switch Timer].
All the destination information shown on the display.
In the fax settings, address book data is stored with entry IDs, which the system internally assigns to each data. The entry IDs may be changed due to re-assigning in backup/restore operations.
Make sure that there is no transmission standby file. If any standby file exists, ask the customer to delete it or complete the transmission.
Turn OFF the main power and unplug the power cord.
Turn ON the main power again to discharge the residual charge.
Replace the NVRAM with a new one.
Turn ON the main power.
For SP 5300/5310, SC995 will be displayed after turning ON the main power.
For MP 501/601, SC995 might be internally issued after turning ON the main power.
After turning ON the main power, SC870 will occur and the address book data will be cleared.
For MP 501/601, change the following SP settings for the operation panel after turning ON the main power.
SP5-748-101: (OpePanel Setting: Op Type Action Setting): Change bit 0 from "0" to "1".
SP5-748-201: (OpePanel Setting: Cheetah Panel Connect Setting): Change the value from "0" to "1".
For MP 501/601, change the Flair API SP values.
SP5-752-001 (Copy FlairAPIFunction Setting): Change bit 0 from "0" to "1".
SP1-041-001 (Scan:FlairAPI Setting) in Scanner SP: Change bit 0 from "0" to "1".
SP3-301-001 (FAX:FlairAPI Setting) in Fax SP: Change bit 0 from "0" to "1".
Turn OFF/ON the main power with the SD card where the NV-RAM data has been uploaded in SD slot 2.
Download the NV-RAM data stored in the SD card to the brand-new NV-RAM using SP5-825-001 (NV-RAM Data Download).
The download will take a few minutes.
Turn OFF the main power and remove the SD card from SD Card Slot 2.
Turn ON the main power.
Restore the original settings of the following SPs, by referring to the SMC data obtained in step 2.
SP5-825-001 does not download the following SP data to the new NV-RAM. You must set them manually.
SP5-985-001(Device Setting: On Board NIC) (MP 501/601 only)
SP5-985-002(Device Setting: On Board USB) (MP 501/601 only)
SP5-193-001 (External Controller Info. Settings)
SP5-730-001 (Extended Function Setting: JavaTM Platform setting) (MP 501/601 only)
For MP 501/601, if the security functions (HDD Encryption and HDD Data Overwrite Security) were applied, set the functions again.
Ask the customer to restore their address book. Or restore the address book data using SP5-846-052 (UCS Setting: Restore All Addr Book), and ask the customer to ensure the address book data has been restored properly.
If you have obtained a backup of the customer’s address book data, delete the backup immediately after the NVRAM replacement to avoid accidentally taking out the customer’s data.
Output the SMC log using one of the following methods:
To print SMC log data, execute SP5-990-001.
To save SMC log data to an SD card, execute SP5-992-001 (SMC List Card Save Function).
Check that the counters are reset.
For MP 501/601, make sure that the list output in steps 7-1 through steps 7-3 matches the destination information in the machine. If not, set it to the setting before replacement.
Try the following if NVRAM upload (SP5-824-001) or download (SP5-825-001) cannot be done.
Check the SP values that changed on the SMC you printed out in step 2. Adjust the values manually. Make sure that the values of SP5-045-001 (MP 501/601 only) and SP5-302-002 are the same as before replacing.
If a message tells you need an SD card to restore displays after the NVRAM replacement, create a "SD card for restoration" and restore with the SD card. Refer to the following.
