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 XpertJet with 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.

Current version 1.11

V1.10

Changes:

• Users may mistake "Longstore" for a stronger version of cleaning and perform "Longstore" in user mode. The printer will be left in an unfilled state and will be difficult to recover from.
  - Before "Longstore" is performed, a message will be displayed on the panel indicating that a cleaning cartridge is required.
  - Before "Longstore" is performed, make it possible to exit the menu by pressing the Cancel key.
• Change the status display on MSM during soak cleaning from "Cleaning" to "Soak cleaning".
• When the ink status "[**] Check color" message was displayed, the status LED on the panel was lit green.

Bug fixes:

• When an ink-related error occurs, the "soak cleaning" process starts, and the panel becomes inoperable during the process.
• The backlight of the control panel keys may flickers momentarily while the setting screen is displayed.
   "[**] Check color" is the same as error. Therefore, it has been changed to light up a red status LED.
• 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.
• Ink-related warning messages are not displayed correctly in Western European language settings.
• If the display language setting is changed while a warning message is displayed on the main panel, unintended characters may be mixed in with the warning message immediately after the change.
• When the origin setting is complete, the "Cover open" message disappears. The message now continues to be displayed.

Installed Ver 1.10 Serial number:
 XPJ-1641SR-P : KF6U001659~

Release date: 14 August  2024

Bug fix:

1/ There was a problem with the "head soak" cleaning cycle that was added in the previous version.

- When performing the soak cleaning process while a media error (e.g. no media) is displayed, the carriage moves to the left and then immediately returns to the cap-in position.

- When pressing Enter with the cleaning solution filled into the cap, the soak time is entered after cap-in, but the process of sucking up the cleaning solution occurs when the cap is in. This means that the cleaning solution inside the cap is drained and the print head is not soaked.

  - When entering the soak time, if the set time is not confirmed, the process does not move to the next step. At this time the cap is in a soaking state, but because the soaking time is not being counted, it is not recorded in the log.

2/ In some cases cleaning cannot be performed from the remote panel.

Installed Ver 1.09 Serial number:
XPJ-1641SR-P : KF6U001589~

v1.08

Release date: 04 June 2024

Changes:

1.  Added the message that the media cannot be cut when media detection setting is "OFF".

2. Added a "head soak" procedure in user mode (Menu 12: Soak clenaing)

This procedure can be used to soak the head in the cap when nozzles remain misfiring or missed.

Procedure:

Menu 12 head soak > head soak start > Enter

Carriage moves to the left side of the printer. (same operation as CR maintenance)

Open the front cover and maintenance cover R.

Fill the cap with the maintenance fluid with the dropper until the cap is just full.

Close the maintenance cover R and front cover.

Soak time (1-99) 10min > Enter

Automatic cleaning after soak time has elapsed.

3. Using certain antivirus software packages sometimes caused a CPU error: this is is now fixed.

Installed Ver 1.08 Serial number:
XPJ-1641SR-P : KF6U001479~

v1.07

Release date: 01 August 2023

Changes:

1/  Added patterns for head slant adjustment.
These patterns may improve the accuracy of head tilt adjustment and improve print quality.
New patterns (Self-diagnosis mode>Adjustment>Head Slant)
Slant V-1
Slant V-2
 A high magnification loupe(x200~x400 e.g. Digital loupe) is required for adjust with these patterns.

2/ Acceleration of paper feed during printing can be changed
This is a useful feature if slippery media is used.
New setting (Self-diagnosis mode>Parameter>Update>PF Acc.)
"Normal":Default
"Low": Low acceleration
 *Note the impact on throughput.

Installed Ver 1.07 Serial number:
XPJ-1641SR-P : KF6U001069~

v1.06

Bugfixes:

1/ The added "spitting" feature in Auto cleaning> Standby in FW1.05 did not work correctly. The amount of ink spit was too low resulting in an ink mix in printing after this spitting: This is now solved.

v1.04

Updating to F/W Ver1.04 requires MSA tool Ver.5.1.1 or higher. 

• The ‘L’, ‘M’ and ‘H’ stand for ‘Low’, ‘Medium’ and ‘High’ intensity weaving.
  Lower intensity prints faster and gives lower banding suppression.
  Higher intensity prints slower and gives most banding suppression.
• The previous print effects remain available in the firmware.
  The new ones, however, will become the first choice & Mutoh’s recommendation.

2. Profiling guidelines:

To obtain best results, Mutoh also wants to promote specific dot distribution/transition settings for variable drop profiling.
These settings control the balance among small, medium and large drops for a certain target output density.

• Small drop limit:       max. 30%.
• Middle drop limit:     max. 60%.
• Large drop limit:       max. 100%.

The impact of this setting is illustrated in the graph below.

In VerteLith V5.1.0, using the latest Profiler version (V2.4.0), the screen to adjust the variable dot limits is shown in the illustration below:

• Where possible, the recommended starting values are pre-filled.
• For cases where Mutoh recommends to eliminate a drop size, a value of ‘2’ is prefilled.
  To completely eliminate a drop size, it needs to be manually set to ‘0’ (zero).

4. New wave form for ink fly suppression:

• Mutoh has noticed that a combination of circumstances (print conditions as well as environmental conditions) may cause ink-fly (mist) occurring over the print surface as well as in the margins. In case you observe ink-fly on a printer, please choose the new ‘Type B’ Waveform to suppress the ink-fly.
• Since the Waveform Type selection has a slight impact on the generated drop masses, operators may observe a slight colour shift when changing to the new waveform selection.

The improved behaviour is shown in the illustrations below.

Situation with ink-fly occuring using Type A waveform	Same print/environmental conditions using Type B waveform

4.1 The new waveform setting can be found in the diagnostics mode under menu: Parameter > Update > WF . Type

4.2 Possible wave form selections: Type A and Type B.

4.3 If a waveform is selected, it is applicable for:

• New machines being installed.
• Installed base machines upgraded from a lower F/W version.

4.5 Type B setting has an impact only on the jetting behavior when using ‘LOW2’ head height.

4.6 The impact of ‘Type B’ selection is limited to following drop families:

• MS41 Ink:          VSD1 and VSD3
• MS51 Ink:          VSD1
• UMS Ink:            VSD1
• For all other ink-drop family combinations ‘Type B’ behaves exactly like ‘Type A’.

5. Overview XPJ-1641SR-P - Ink Type - Head Height - Drop Family - Waveform Compatibility

v1.01

Bug Fixes:

1. The setting made from the panel with the menu of "Self-diagnosis> Parameters> Update> UniD/BiD", was not saved: this is now fixed.
 * This error does not occur when adjusting with the "Adjustment> Uni / Bi" menu.

2. Even if the alert buzzer is set to off, pressing a key is requested when the ink near end or ink end condition comes: this is now fixed not to request it.

3. If the cancel key is pressed just before the printhead is capped in, all keys become invalid except the main switch: this is now fixed.

4. The item number of a menu was incorrect when printing the setup list: It is fixed from [25] Heater Ctrl to [24] Heater Ctrl. 

5. A loud sound generated with a high-speed movement of the CR, after power-on flushing when PG is in the High position: this is now fixed.

Changes:

1. The periodically displayed "Perform Adjust Print" message is no longer displayed.

2. The total operating time of the Auto UniD / BiD adjustment or Auto PF adjustment has been reduced as follows;
[Auto UniD / BiD] From 14:53 to 06:26
[Auto PF adjustment] From 01:22 to 00:56

3. Improved jetting wave form for Large (VSD1) and Middle (VSD2) drop families.
Mist reduction when using MS41 in combination with the Middle and High head heights.

4. Improved jetting wave form for small drop family (VSD3). Image noise reduction thanks to improved dot positioning.

5. The effect pattern is now changed under the following print conditions to improve the print quality.
Resolution: 1200x1200
Waveform: VSD3
Effect: i-Screen4~6

Installed Ver 1.01 Serial number:
 XPJ-1641SR-P : KF6U000318~

Important note:

When updating towards firmware version v1.02, make sure to use MSA tool Ver.5.0.9.0 or higher

Please make sure to use heater FW 7.01 or higher on this model.

v1.00

First firmware release

** Make sure when updating to F/W Main Ver1.11 or higher to use MSA tool Ver.6.0.6 higher.
 

Bug fix:

• Backup parameters may not be saved to non-volatile memory after ink charge.
• When printing data created with Fiery's RIP, missing dots and misaligned printing of specific colors occur.

Changes:

• The system will be changed to keep the power on so that the power does not turn off for long periods of time.
  The power button will switch the device to sleep mode and return it to sleep mode, and power off will be done from the Settings > Power Off menu. See TIB 877.
• If no printing operation is performed for the set time, the printer will automatically enter sleep mode.
   In the Sleep Mode menu, select "Auto Sleep Timer" to set the time until the printer enters sleep mode from 4, 8, 12, or 24 hours. (Default: 4 hours)
• The default values for "auto cleaning" and "cleaning during sleep mode" will be changed.
  • Autocleaning (Standby) ==> CL Type : Spitting -> Spitting (Even if it was set to something other than Spitting before the update, it will be changed to Spitting after the update.)
    Waiting Time : 360min (MS31), 120min (MS51)
  • Sleep Mode ==> CL type : Spitting -> Short CL
     Cleaning Timer : 3H -> 7days (MS31), 3days (MS51)
• The behavior after waking up from sleep mode will change (MS51only):
  When waking up from sleep mode, if more than 120 minutes have passed since the most recent cleaning, cleaning will be performed.
  The cleaning type performed will be the cleaning type set in sleep mode. However, if spitting is set, short cleaning will be performed.
• If auto cleaning cannot be performed due to the cover being open or some other error, the print head nozzles may become clogged.
   To prevent a long period of time from passing without being able to perform maintenance operations such as auto cleaning, the printer will display an error message and beep to notify the user.
• If the power was left on for 24 hours, backup parameters, including the "Printer Usage" log, were sometimes not recorded in memory. Backup parameters are now recorded in memory on a 24-hour cycle.
• Previously, in power saving mode, the vacuum fan was fixed to stop when the standby heat timed out. However, if there is communication to periodically check the printer status, such as VerteLith, the printer cannot switch to power saving mode. This will be changed so that the vacuum fan also stops when the heater is turned off.
