Description: Software performance error The software attempted to perform an unexpected operation due to: 1) software bug, 2) incorrect internal parameter, 3) insufficient working memory.
Remedy: • Turn the machine power off/on • Reinstall the controller and/or main firmware Note: When this SC occurs, the file name, address, and data will be stored in NVRAM. This information can be checked by using SP7-403. Note the above data and the situation in which this SC occurs. Then report the data and conditions to your technical control center.
Code: 991
Description: Software continuity error The software attempted to perform an unexpected operation. However, unlike SC990, the object of the error is continuity of the software.
Causes: • Software program error • Internal parameter incorrect, insufficient working memory.
Remedy: This SC is not displayed on the LCD (logging only).
Code: 992
Description: Unexpected Software Error Software encountered an unexpected operation not defined under any SC code.
Causes: • Software defective • An error undetectable by any other SC code occurred
Remedy: Print the "Logging Data" with SP5990-004 and then check the SP7990. If 498-Engine is found in the SP7990; 1. Check the harness connection of the temperature/humidity sensor. 2. Replace the temperature/humidity sensor.
Code: 994
Description: OCS record limitation error 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.
Causes: • No action required because this SC does not interfere with operation of the machine.
Remedy: • No action required because this SC does not interfere with operation of the machine.
Code: 995
Description: Controller Board Mismatch
Causes: • Defective BCU • NVRAM Replacement error
Remedy: -001 • Defective BCU • NVRAM Replacement error 1. Install the previous NVRAM. 2. Input the serial number with SP5811-004, and turn the main power switch off/on. IMPORTANT: When the BCU is replaced with a new one, this SC will occur. Therefore, make sure to do Step #2 above. Turning the power off/on links the NVRAM with the S/N information in the BCU. -002 • Defective NVRAM • Defective controller 1. Update the controller firmware. 2. Install a new NVRAM, and turn off and on the main power switch after SC995-002 has occurred. IMPORTANT: When the NVRAM is replaced with a new one, this SC will occur. Therefore, make sure to do Step #2 above. Turning the power off/on allows the NVRAM to recognize the S/N. -003 • Incorrect type controller installed • Defective controller Replace the controller with the correct type. -004 • Incorrect model controller installed. Replace the controller with the correct model.
Code: 997
Description: Application function selection error The application selected by the operation panel key does not start or ends abnormally.
Causes: • Software (including the software configuration) defective • An option required by the application (RAM, DIMM, board) is not installed • Nesting of the fax group addresses is too complicated
Remedy: 1. Check the devices necessary for the application program. If necessary devices have not been installed, install them. 2. Check that application programs are correctly configured. 3. For a fax operation problem, simplify the nesting of the fax group addresses. 4. Take necessary countermeasures specific to the application program. If the logs can be displayed on the operation panel, see the logs.
