SC 925 Net File function error
-00 – HDD is defective
-01 – NetFile management file is broken
– The NetFile file management on the HDD cannot be used, or a NetFile management file is corrupted and operation cannot continue. The HDDs are defective and they cannot be debugged or partitioned, so the Scan Router functions (delivery of received faxes, document capture, etc.), Web services, and other network functions cannot be used.
HDD status codes are displayed below the SC code.
 Refer to the four procedures below (Recovery from SC 925).
Here is a list of HDD status codes:
Display Meaning
(-1) HDD not connected
(-2) HDD not ready
(-3) No label
(-4) Partition type incorrect
(-5) Error returned during label read or check
(-6) Error returned during label read or check
(-7) “filesystem” repair failed
(-8) “filesystem” mount failed
(-9) Drive does not answer command
(-10) Internal kernel error
(-11) Size of drive is too small
(-12) Specified partition does not exist
Display Meaning
(-13) Device file does not exist
Recovery from SC 925 Procedure 1
If the machine shows SC codes for HDD errors (SC860 to SC865) with SC 925, do the recovery procedures for SC860 to SC865.
Procedure 2
If the machine does not show one of the five HDD errors (SC860 to SC865), turn the machine power off and on. If this is not the solution for the problem, then initialize the NetFile partition on the HDD with SP5832-011 (HDD Formatting – Ridoc I/F).
NetFiles: Jobs printed from the document server using a PC and DeskTopBinder
 Before you initialize the NetFile partition on the HDD, tell the customer that:
 Received faxes on the delivery server will be erased
 All captured documents will be erased
 DeskTopBinder/Print Job Manager/Desk Top Editor job history will be erased
 Documents on the document server, and scanned documents, will not be erased.
 The first time that the network gets access to the machine, the management information must be configured again (this will use a lot of time).
Before you initialize the Netfile partition with SP5832-011, do these steps:
1. Go into the User Tools mode and do “Delivery Settings” to print all received fax documents that are scheduled for delivery. Then erase them.
2. In the User Tools mode, do Document Management> Batch Delete Transfer Documents.
3. Do SP5832-011, then turn the machine power off and on.
Procedure 3
If “Procedure 2” is not the solution for the problem, do SP5832-001 (HDD Formatting – All), then turn the machine power off and on.
SP5832-001 erases all document and address book data on the hard disks. Ask the customer before you do this SP code.

Procedure 4
If “Procedure 3” is not the solution for the problem, replace the HDD.

SC 990 Software error 1
The software performs an unexpected function and the program cannot continue.
 Software defective, re-boot

SC 991 Software error 2
The software performs an unexpected function. However, unlike SC990, recovery processing allows the program to continue.
 Software defective, re-boot

In order to get more details about SC990 and SC991:
1) Execute SP7403 or print an SMC Report (SP5990) to read the history of the 10 most recent logged errors.
2) If you press the zero key on the operation panel with the SP selection menu displayed, you will see detailed information about the recently logged SC990 or SC991, including the software file name, line number, and so on.

 1) is the recommended method, because another SC could write over the information for the previous SC.

SC 992 Undefined error
Defective software program
 An error undetectable by any other SC code occurred

SC 994 Application Item Error
The number of executed application items on the operation panel reach the maximum limit for the operation panel structure.
 Too much executed application items
