HDD status codes are displayed below: |
| Causes: | 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: |
| Remedy: | Procedure 1 If the machine shows SC codes for HDD errors (SC860 ~ SC865) with SC 925, do the recovery procedures for SC860 ~ SC865. Procedure 2 If the machine does not show one of the five HDD errors (SC860 ~ 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). 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 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. |
| Error code: | SC951 |
| Description: | F-Gate Signal Error When the IPU has already received the F-GATE signal (laser writing start trigger signal), the IPU receives another F-GATE signal. |
| Causes: | • Firmware defective • Update the BCU firmware. • BCU defective |
| Error code: | SC953 |
| Description: | Scanner Image Setting Error The settings required for image processing using the scanner are not sent from the IPU |
| Causes: | • Check the harnesses, connectors between the MCU and BCU • Update the BCU, MCU firmware • MCU defective • BCU defective • IPU defective |
| Error code: | SC954 |
| Description: | Printer Image Setting Error The IPU did not issue the signal required to start image processing for the printing mode within 60 s after the paper stops for registration. |
| Causes: | • Software defective • Replace the software (all firmware modules). • IPU defective |
| Error code: | SC955 |
| Description: | Memory Setting Error The settings that are required for image processing using the memory are not sent from the IPU. |
| Causes: | • Software bug • Hard disk unit defective • Controller defective • MCU defective • IPU defective |
| Error code: | SC964 |
| Description: | Scanner Start Error During scanned image processing, another command to start scanning was received. |
| Causes: | • Software bug |
| Error code: | SC965 |
| Description: | Print start signal error 1 The printer received another print start signal after print job has already started. |
| Causes: | • Main machine firmware defective • Replace all firmware modules on the main machine |
| Error code: | SC966 |
| Description: | Polygon Mirror Motor Ready Error The polygon mirror motor does not reach ready status within 15 s after the copy paper is detected by the registration sensor. (15 s after the write request was issued for the IPU, the FGATE signal remained LOW.) |
| Causes: | • Polygon mirror motor harness, connections to BCU loose, broken, defective • Polygon mirror motor drive board harness, connector to BCU loose, broken, defective • Polygon mirror motor defective • Polygon mirror motor drive board defective • BCU defective |
| Error code: | SC970 |
| Description: | Scanner Ready Error The scan ready signal is not generated by the MCU for more than 10 s after the read start signal is sent to the MCU. |
| Causes: | • Software bugSoftware bugny • Harnesses, connectors to the MCU loose, broken, defective • MCU defective • BCU defective |
| Error code: | SC990 |
| Description: | Software error 2 The software performs an unexpected function and the program cannot continue. |
| Causes: | An unexpected operation was encountered by the software. |
| Remedy: | • Software defective, re-boot 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. |
| Error code: | SC991 |
| Description: | Software error 3 The software performs an unexpected function and the program cannot continue. However, unlike SC990, recovery processing allows the program to continue. |
| Causes: | The software peformed an unexpected function and the program cannot continue. Recovery processing allows the program to continue. |
| Remedy: | • Software defective, re-boot 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. |
| Error code: | SC994 |
| Description: | Operation Panel Management Records Exceeded |
| Causes: | An error occurred because the number of records exceeded the limit for images managed in the service layer of the firmware. This can occur if there if there are too many application screens open on the operation panel. |
| Remedy: | • No action required because this SC does not interfere with operation of the machine. |
| Error code: | SC997 |
| Description: | Cannot select application function An application does not start after the user pushed the correct key on the operation panel. |
| Causes: | An application did not start after pressing the appropriate key on the operation panel. |
| Remedy: | • Software bug • A RAM or DIMM option necessary for the application is not installed or not installed correctly. |
