1. Prepare an SD card.
2. Create a directory named “restore_key” inside the root directory of the SD card. Then,
save the “nvram_key.txt” file using the following name:
/restore_key/nvram_key.txt
3. Create a text file and write "nvclear".

Write this string at the head of the file.

Use all lower-case letters.
Do not use quotation marks or blank spaces.
It is judged that a forced start has been selected when the content of "nvclear" is
executed and the machine shifts to the alternate system (forced start).
4. Confirm that a message is displayed on the LCD telling to insert the SD card that
contains the encryption key.
5. Turn off the main power.
6. Insert the SD card that contains the encryption key into SD card slot 2 (the lower slot).

Subject: Cannot send/receive faxes (Memory Full / Prepared by: Y. Taniguchi
Remain in the machine)
From: 1st FQM Sect., 1st FQM Dept.
Classification: Troubleshooting Part information Action required
Mechanical Electrical Service manual revision
Paper path Transmit/receive Retrofit information
Product Safety Other ( ) Tier 2

Important
There are two independent problems about the fax function (“Memory reaches full”
and “Document is waiting and remains in the machine”). They are not related
directly but the symptoms and countermeasures is similar, so they are mentioned
together in this RTB.
Problem 1: Memory reaches full
SYMPTOM
“FAX memory is reached limit” is displayed and the machine cannot receive or send faxes
when all of the following conditions are met:
1) Forwarding is enabled.
2) The transmission destination type for Forwarding is set to [Folder].
3) HDD is installed.
4) A large document is received.
Note: This corresponds roughly to 320 A4-sized pages of a normal text document, or
fewer pages in the case of images (Example: 6 A3-sized pages of a C4 color chart
printed).

CAUSE
Under the conditions explained above, invalid data is received (copied) into fax memory.
The machine cannot copy the data to the HDD (which is normal when using Forward to
Folder), and continues to retry for up to 72 hours. As a result, the fax memory is locked
during this time, and the machine cannot send or receive faxes.

SOLUTION
On the Production line
FCU Firmware is modified so that the default value of the third digit from the bottom of SP1-
104-003 is “0”. The setting value means invalid data will not be stored in fax memory.
 Technical Bulletin PAGE: 2/3

Reissued: 17-Jan-17
Model: MT-C6 Date: 16-Dec-16 No.: RD223037a

Problem 2: Document is waiting and remains in the machine

SYMPTOM
Faxes that require internal communication with the HDD cannot be sent and remain
in the machine, and the Transmission Failure Report is not printed out. Customers
may be unaware of non-transmission.
Conditions:
1). Capturing Device Log function is enabled (Default: enable).
2). Capturing Device Log accesses the HDD just as the machine switches to Sleep Mode.
3). The fax is sent using a feature that requires internal communication with the HDD, i.e.:
Preview Before Transmission
Remote Fax (either as the Main machine or Sub machine)
Sending the document stored in Document Server

CAUSE
When the conditions 1) and 2) described above are met, the line of communication
between the HDD and machine is locked and remains locked. Fax features that require
internal communication with the HDD use this same line, which then prevents fax
transmission.

SOLUTION
On the Production line
FCU Firmware is modified to release the line of communication between the
machine and HDD under the conditions described above.
 Technical Bulletin PAGE: 3/3

Reissued: 17-Jan-17
Model: MT-C6 Date: 16-Dec-16 No.: RD223037a

Important:
In the case of troubleshooting either problem, please do the following procedure in
order to prevent both problems.

SOLUTION In the field

1) Update the GWFCU firmware to the following version or later:
Firmware Name P/N Version
GWFCU3.8-13 D2235546E 04.00.00

2) Set the third digit from the bottom of FAX SP1-104-003 to “0” (“Delete invalid data”).
Note: This is because the SP value will not be changed if only the firmware is updated.
Only the default value is changed by the firmware update.

SYMPTOM
SC555 occurs.

CAUSE
The bracket for the side/rear internal thermistor is not the optimum size, which prevents the
thermistor from contacting the hot roller correctly. As a result, the machine cannot detect the
correct temperature of the hot roller.

SOLUTION
Replace the bracket with the modified one (D2234195)

Service Manual Correction

Log capturing information was corrected and added in red in the following section of the
Service Manual:
6. System Maintenance > Capturing Debug Logs

Overview
With this feature, you can save debug logs that are stored in the machine (HDD or operation panel) on
an SD card. This function allows the Customer Engineer to save and retrieve error information for
analysis. The Capturing Log feature saves debug logs for:
• Controller device log including operation log
• Engine device log
• Operation panel log
• FCU device log

• In older models, a technician enabled the logging tool after a problem occurred. After that, when the
problem had been reproduced, the technician was able to retrieve the debug log.
• However, this new feature saves the debug logs whenever a problem occurs, and then this log can
be saved to an SD card.
• You can retrieve the debug logs with an SD card without a network.
• Analysis of the debug log is effective for problems caused by the software. Analysis of the debug
log is not valid for the selection of defective parts or problems caused by hardware.
• Make sure to shut down and reboot the machine once before retrieving the Debug Logs. Otherwise,
the latest settings may not be collected when the debug logs are retrieved.

Service Manual:
6. System Maintenance > Capturing Debug Logs

Overview
With this feature, you can save debug logs that are stored in the machine (HDD or operation panel) on
an SD card. This function allows the Customer Engineer to save and retrieve error information for
analysis. The Capturing Log feature saves debug logs for:
• Controller device log including operation log
• Engine device log
• Operation panel log
• FCU device log

• In older models, a technician enabled the logging tool after a problem occurred. After that, when the
problem had been reproduced, the technician was able to retrieve the debug log.
• However, this new feature saves the debug logs whenever a problem occurs, and then this log can
be saved to an SD card.
• You can retrieve the debug logs with an SD card without a network.
• Analysis of the debug log is effective for problems caused by the software. Analysis of the debug
log is not valid for the selection of defective parts or problems caused by hardware.
• Make sure to shut down and reboot the machine once before retrieving the Debug Logs. Otherwise,
the latest settings may not be collected when the debug logs are retrieved.

And System/Copy Firmware Version has been changed as below.

D2235540 -> D2235565
Version 1.17 Version 1.18

Caution
There is interchangeability between the new CTL board and the firmware.
Old System/Copy firmware (version 1.17) cannot be used for new CTL board.
If you use a new CTL board, do not downgrade the System/Copy firmware to version 1.17.
If the old System firmware is installed to the new CTL board, SC878 (TPM authentication
error) will occur.
If SC878 occurs after downgrading the firmware, the CTL board has to be replaced to
solve the SC878.

Change/Reason:
An IC on the CTL board has been discontinued. The new IC is not compatible with the old
one and required a firmware change.
