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.

• Do not remove the USB memory while this tool is running. If the usb is removed, check that the value of 08-9010 is “0” after use.

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. o If it was turned OFF, check that the value of 08-9010 is "0" after use. o If 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:

o The 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. o A USB hub is connected. Remove the USB hub and connect only the USB

memory that stores the Diagnostic tool. o A USB connection device other than a USB memory is connected to the main

unit. Connect only the USB memory that stores the Diagnostic tool. o The 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.

Introduction

This manual describes the procedure for using the SYS Board Diagnosis Tool. This tool inspects the parts function of the SYS board, the communication functions connecting with other boards, and the HDD function. The setting values saved in the machine, and the software are not erased. Do not use this tool for other purposes.

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.

Target Models

This tool can only be used on the following models. It does not work properly on any other models.

• e-STUDIO2010AC/2510AC

• e-STUDIO2015C/2515AC/3015AC/3515AC/4515AC/5015AC

• e-STUDIO2018A/2518A/3018A/3518A/4518A/5018A

• e-STUDIO5516AC/6516AC/7516AC

• e-STUDIO5518A/6518A/7518A/8518A

USB Memory Requirements

A USB memory must be formatted in FAT 32 and meet the following requirements:

• Capacity 1GB above

• USB 2.0 or higher

Note: A USB memory that is 32GB or larger must be formatted with exFAT.

Procedure to Use the Diagnostic Tool

1. Make sure that the Main power switch is turned OFF, and then disconnect the power cable.

2. Remove the Rear Cover of the MFP.

3. Remove the SYS Board Cover (the screw positions differ depending on the model).

6

4. Remove the short pin attached to CN106 of the SYS Board and then insert the short

pin on one side of CN106 as shown in the figure below.

5. Insert the USB memory containing the Diagnostic tool into the usb port locate on the

left-side of Control Panel or the upper right side of the machine (the USB memory

insertion slot location differs depending on the model).

6. Insert the power cable into the MFP.

7. Turn on the Main power switch ON (all covers must be closed).

8. The following screen with a progress bar will be displayed and the automatic check

process is started.

9. When the tool diagnosis has complete, the judgment of OK or NG as shown in the

example figure below is displayed on the LCD of the Control Panel.

10. When the result is displayed and the buzzer sounds, press and hold the power button for

approximately 5 seconds to turn the power OFF. Then turn the Main power switch OFF.

11. After confirming that the power is turned OFF, remove the USB memory. The USB will

contain a compressed file with test results saved.

File name：(inspection time)_(machine S/N)_SYS.zip

Example：20200903133800_CNAH00523_SYS.zip

Note: The compressed test result file cannot be accessed with a computer and is for

use by the factory for additional troubleshooting when necessary.

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. Refer to the Correspondence table (below) and take the corrective action.

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

20

(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 as shown 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.
