Precautions
•Use the System Board Diagnostic tool prior to using the Logic Board Diagnostic tool.
•This tool is only for use with the models listed in ‘Target Models’below. It will not
work on models that are not listed.
•Be sure to use the tool with the mfp covers closed.
• DonotremovetheUSBmemorywhilethistoolis running. Ifthe usb is removed,check
that the value of 08-9010is“0”afteruse.
o If the value is anything other than "0", set it to “0”.
•Do not turn the power of the main unit OFF while using this tool.
oIf it was turned OFF, check that the value of 08-9010 is "0" after use.
oIf the value is anything other than "0", set it to “0”.
•If "USBMOUNTING: NG" (shown below) should occur when using the Diagnostic tool,
the following can be considered:
oThe USB memory is not formatted in FAT32. Format the USB memory with
FAT32. A USB memory of 32GB or larger in size must be formatted in exFAT.
oA USB hub is connected. Remove the USB hub and connect only the USB
memory that stores the Diagnostic tool.
oA USB connection device other than a USB memory is connected to the main
unit. Connect only the USB memory that stores the Diagnostic tool.
oThe USB harness on the SYS board is not connected properly. Make sure that
the white USB harness connected to the SYS board and the black USB harness
next to it are not connected in reverse (see below).
•If "USBMOUNTING: NG" still occurs even after taking the above measures,
discontinue use and try using a different USB memory device.
•If the following screen is displayed, save the Diagnostic tool in the USB memory
again and then try again.

Use this tool when any of the following symptoms has occurred:
•The cause of the call for service is not known and replacing the SYS board is
determined (Conditions of the SYS board are checked).
•The equipment does not start (Control Panel is not displayed)
•A call for service related to the SYS board has occurred.
•A call for service related to the HDD has occurred.
•AN “F” series error has occurred.

Procedure when the Result is NG
When NG occurs, a screen like the one shown below is displayed on the Control Panel.
1. Check the item(s) in red.
2. R efertotheCorrespondencetable(below) andtakethe correctiveaction.
The inspection number and item results are displayed on the Control Panel. Check the
inspection number and items displayed in red ("NG" and OK?) according to the table below.
Note: If replacement of the SYS board, Main Memory, SRAM (FRAM) and FAN etc. is
required, refer to the replacement procedure in the service manual.
Important Note:
A result of “NG”when using the Diagnostic tool could be caused by reasons other than a
failure of the SYS board such as wiring harness related issues or wire harness connections
to other components.

Procedure when the result is OK
Inspection results of optional items such as the USB Host and Fax will not show as
"NG", so check it separately if necessary. Items to be confirmed are displayed as
“OK?” in red. Items marked with "OK" in black have been confirmed and there is not
a problem.
In the case of software related errors such as system firmware and other
software, the judgement result is often displayed as OK. If necessary, perform
HDD format and reinstall the software.
If the inspection result is "OK?", refer to the option connect status in the Table below.
Check the connection status of the option and then troubleshoot if necessary.

Troubleshooting when the tool does not function
When the tool does not function properly, check the following items.
(1) When the USB memory is not recognized, or the file cannot be read.
If the following screen is displayed, confirm the ‘Items to check’below.
Items to check
・Reinsert the USB memory.
・Check the folder name and the file name in the folder.
(Refer to " USB Advanced Preparation" above).
・Re-install the program files on the USB memory.
・Replace the USB memory.
・If there is a "SystemRomRecovery" file directly under the USB memory being
used, remove the file or change the file name.
(2) When the files are corrupted
If the following screen is displayed, re-install the program files on the USB
memory.
Starting recovery mode...
USB memory is not detected. Please insert the proper USB memory,
then reboot the machine

(3) When "RESULT : USB MOUNT NG" is displayed on the Control Panel
If the following screen is displayed, confirm the following.
Check if the USB memory mounting position is as shown in the figure below.
Check if the connector mounting position (indicated by the red box) is asshown in
the figure below.
Check if the file systems in the USB memory is formatted in FAT32. If the file system in
the USB memory isn't formatted in FAT32, format the USB memory in FAT32.
(4) When the tool cannot be used
If the tool cannot be used even after performing the above, refer to the service manual.
