Necessary tools

In order to be able to install firmware, the following tools are required:

• Personal computer with MS Windows
• Network cable to connect the Valuejet wit the pc
• The latest MSA-tool (Mutoh Service Assistance) or MSM-tool (Mutoh Status Monitor)

Detailed instructions how to install the firmware, are described in the maintenance manual.

The latest current firmware can be downloaded below this article.

Release date:  15 January 2026

Current version - 1.20

* When you update to F/W Main Ver1.20, please you make sure to use MSA tool Ver.6.0.60 or higher

Bugfix:

1/ When printing only white (*WL10) and then printing layers twice, the print position of the second layer and above is shifted in the second layer print. 

2/ When printing data created with Fiery's RIP, missing dots and misaligned printing of specific colors occur.

3/ When printing continuously with the VerteLith with the media cut enabled, printing may stop midway after printing a few sheets.

4/ During media detection, user type selection, or media thickness correction input, the screen times out and the printer proceeds to the next operation (paper width detection).

Added:

1/ Add soak cleaning menu to user mode.

2/ Using the printer in a temperature environment outside the guaranteed operating range may cause mechanical problems or physical problems (the ink may change quality or not curing).
To prevent and suppress such problems, a warning will be displayed on the main panel and on VerteLith and MSM if the printer temperature (temperature information for head 1) falls below 18C or exceeds 50C. If the printer temperature falls within the guaranteed operating range, these warnings will automatically disappear.

3/ "Custom Mode" menu to Self-Diagnosis > Parameters > Update.
 *This is for internal testing purposes and will not be used in the field.

Update to 1.20 Serial number:
VJ-1638UH : End of production

Version history

Release date: 11 June 2025

1.19

* When you update to F/W Main Ver1.19, please you make sure to use MSA tool Ver.6.0.5.0 or higher

Bugfix:

1/ A CPU error occurs when connecting to a PC with antivirus software (AVG AntiVirus) installed.

2/ When the smart chip terminal short circuit occurs due to the misalignment of the smart chip card attachment position on the ink cartridge, the chip recovery may not function and an I/C error may occur.
 Fixed: chip recovery to work even in such cases.

3/ If printing is canceled during layer printing, the printing position of the second layer may be shifted when printing the next layer print data.

Changed items:

1/ The threshold value was changed because "Check Ink" errors occur frequently when using a high capacity ink pack adapter.

2/ If the ink bag is removed without removing the high capacity ink pack adapter while stirring the ink, the ink end detection flag will react and the ink is out flag will be set.
 Only when the printer is in standby mode and not consuming ink, if the ink pack is removed, "Check ink" will be displayed to prompt the user to check the cartridge status.

3/ The amount of ink consumed recorded in the S/C was less than the actual amount of ink consumed, so when the cartridge end detection flag was detected, there was a discrepancy between the actual amount of ink consumed and the amount written in the S/C, so the message "[**] Check Ink" was displayed.
 The calculation of ink consumption has been revised so that it is closer to the actual amount of ink consumed.

Update to 1.19 Serial number:
 VJ-1638UH : End of production

Release date: 22 January 2025

1.18

* When you update to F/W Main Ver1.18, please you make sure to use MSA tool Ver.6.0.4.0 higher

Bugfix:

When a printer with 6 colors setting is upgraded to Ver.1.17, the first print after the power on will be printed in the wrong colors.

Update to 1.18 Serial number: VJ-1638UH : End of production

Release date: 23 December 2024

1.17

Changed items

1/ [Added] "Longstore" and "Ink Discharge" logs are now recorded. 

The logs can be checked in self-diagnosis mode and with MSA 6.0.5 (to be released) or later.

-User mode:

Ink charge: "UC" on the panel, "Ink charge (User mode)" on the MSA Log list.

Longstore:"UW" on the panel, "Longstore (User mode)" on the MSA Log list

- Self-diagnosis mode:

Ink charge:"CH" on the panel, "Ink charge (Diagnosis)" on the MSA Log list   

Longstore/Discharge:"LO" on the panel, "Longstore (Diagnosis)" on the MSA Log list

2/[Fixed] After upgrading the firmware, an "[ALL] S/C ink error" occurs at startup and the printer cannot start.
Conditions for occurrence:
UH21 ink is used.
The self-diagnosis parameter was changed from "unfilled" to "filled" in Ver.1.14 or earlier, and then the printer was upgraded to Ver.1.15 or Ver1.16.
NOTE: If an error occurs due to this issue, the error will not be recovered even if you upgrade the firmware. It is recommended that you upgrade the firmware before an error occurs whenever possible.
 If an error occurs, please obtain the rdi file and contact MJ.

3/ [Fixed] If initial filling is performed while chip recovery is in operation, the slot where chip recovery was in operation will switch to a different ink type. After that, an S/C ink error will occur.
NOTE: If an error occurs due to this issue, the error will not be recovered even if you upgrade the firmware. It is recommended that you upgrade the firmware before an error occurs whenever possible.
 If an error occurs, please obtain the rdi file and contact MJ.

4/[Fixed] In machines that are charged with six colors of ink, the message "S/C Col. Err" may be displayed even if the correct color S/C card is inserted.

5/[Fixed] When chip trouble is set in ACG, the ink charge progress (%) display is not updated periodically. The display will be updated every second.

6/[Fixed] If printing is canceled while the printer is receiving print data, the machine will down.

7/[Fixed] During chip recovery, "Cleaning -> Ink charge" can be executed even when there is no ink.

  As a consequence, the firmware has been adapted to be able to select the correct "UV Lamp type" depending of the kind of lamp installed. Read the above mentioned bulletin carefully to ensure that the correct lamp type parameter is selected by default:
  
  • LampA
    
    When set to Lamp A, the UV lamp emits the UV light with 100% duty cycle of the specified light intensity
    
    
  • LampB
    
    When set to Lamp B, the UV lamp emits the light with 87% duty cycle of the specified light intensity

Bug correction

Printer could not start printing if the life counter reached a level of 95%. 

This bug has been corrected in case of displaying the circulation pump lifetime message.

Release date: 12 june 2018

1.05

User Mode

• Added an extra PRINT menu option in the Header Dump menu. The PRINT option enables you to print the last header-dump, AFTER a print has been made.
  
  
  
• Improved nozzle-check for better readability when using non-white substrates (user mode)
  
  

Bug fixes

• Parameter update after initial ink-charge
  
  Previously the printer always needed a reboot after ink-charge, in order to properly store the charge-flag in the parameters. When an error occurred after sleep mode, the charge-flag was reset and inks needed to be recharged again if the printer was not properly restarted. From this version, parameters are now properly stored after initial charge without the necessity to reboot.
  
  

New items

• The daily maintenance log, firmware log and ink conversion logs can now be retrieved
  The history logs can now be checked with the latest MSA tool (4.1.7.0 or later). In order to be able to read out the log data, the downloaded PRM file can be loaded in the MSA tool:
  
  
  The contents of the logs may vary, depending on which ValueJet model is being monitored.

The Log List contains 3 different tabs:

• F/W Ver.up
  
  Shows the firmware-update history
  
  
• Ink Conversion
