Error code:	SC925-00
Description:	Net File function error The Net File storage area on the HDD is not available, or the management file used for handling the Net File data is broken. As a result, access to the Net File data cannot be continued.
Causes:	• Defective HDD • HDD inconsistency caused by switching the machine off while writing to HDD • Software bug • When HDD error-related service calls (SC860-SC865) are issued at the same time: This error can be caused by a defective HDD. Therefore, take the necessary countermeasures specified for SC860, etc.
Remedy:	• When other HDD error-related service calls (SC860-SC865) are NOT issued at the same time: 1) Turn the main power off/on. 2) If it cannot be restored by taking the above measure, initialize the Net File partition in the HDD. Note, however, that this may delete stored data such as documents remaining in the Fax transmission queue and those waiting for capture. Therefore, you must obtain the consent of your customer before executing the initialization. Note that after executing commands including Plumeria/Palm2, the job history will also be cleared. 3) If the error persists even after taking the above step, initialize all of the partitions in the HDD in accordance with SP5-832-001, then turn the main power off and then on again. Note, however, that this step will clear all of the data stored on the HDD including various documents, address book data, and so on. Therefore, again you must obtain the prior consent of your customers. Note that saved received Fax documents will be protected, but the receiving order may not be maintained. 4) If the error still cannot be restored, replace the HDD.

Error code:	SC925-01
Description:	NetFile function error The NetFile file management on the HDD cannot be used, or a NetFile management file is corrupted and operation cannot continue.
Causes:	• HDD defective • HDD inconsistency caused by power failure during HDD access, etc. • Software bug
Remedy:	If another SC related to HDD errors (SC860 to SC865) is issued at the same time, the HDD is the cause. Solve the other SC. • If SC860 to SC865 is not issued • Turn the main power off/on. • If this does not work, initialize the HDD NetFile partition (SP5-832-011: HDD Formatting (Ridoc I/F)). Approval by the customer is required because received fax message waiting to be delivered and documents waiting to be captured will be lost. Procedure: 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 SP5-832-011, then turn the machine power off and on. • If this does not solve the problem, initialize all partitions of the HDD (SP5-832-001: HDD Formatting (ALL)), then turn the machine power off and on. Approval by the customer is required because documents and Address Book information in the HDD will be lost. Received fax messages stored are protected but the order may be changed. • If this does not solve the problem, replace the HDD.
