How to switch a XPJ-1341SR-P from UMS11 to UMS21_V5_09-01-2026

MPORTANT:  we advise you to pro-actively replace the ink pump (DG-43907) on field-units in order to ensure a good ink switch. In case the pump is not working 100% anymore the ink switch might result in missing nozzles after the switch. Extra ink charges might be necessary then to get all nozzles active.

 

 

1. Required items:

 

• FW V1.12 (or higher).

• MSA 6.0.6 (or higher)

• Wiper: part number IJ-WIP-02.

• UMS11-CL300E cleaning packs (4 Pieces).

• VJ-MS31-CL220E cleaning cartridges (4 Pieces).

• UMS21 inks.

• New ink pump: part number DG-43907H-40598.

 

2. Procedure:

 

• Install the V1.12 (or higher) firmware. You can use MSA V6.0.6 or later. 

Important ==> All FW versions below 1.07 will not support the UMS21 smart cards !!

 

• Power on the printer in User Mode. 

• Perform a nozzle check (in User mode) to document the current status of the print head.

• Power down the printer.

• Replace the pump to ensure a good ink switch!

• Start the printer in Self-Diagnosis mode.

• Reset the pump life time counter (>parameter>init.counter>pump).

• Follow the instruction on the panel: Insert cleaning - Remove bags - ...

• When the procedure is finished, the panel shows "LONGSTORE".

• Power down the printer.

• Now the printer needs to be configured to be able to accept UMS21 inks:

• Send the MPI file (retrieved via the MSA tool) to the Mutoh Europe Hardware department via the ticketing system (http://support.mutoh.eu).
• Mutoh staff will create a new ULK file (company code) to be able to accept “UMS21”. Upload this ULK file to the printer (via MSA tool).

 

• Replace the wiper.

• Empty the waste bottle.

• Power on the printer in User Mode.

• Display shows: 'INK charge - Start>Enter' , then Press <Enter>.

• Insert NEW MS31 cleaning cartridges.

• After the washing cycle, the display will show: "Wash Retry?". Choose No.

• Perform an 'ink charge' using UMS21 ink.

• Recalibrate the BI-D of the printer. 

• End of procedure.
