How to switch a XPJ-1341SR-P from MS51 to UMS or MS31 inks

IMPORTANT:  we advise you to pro-actively replace the ink pump (DH-40598) 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. 

Required items:

• Latest FW version
• MSA 5.1.2.0. (or higher)
• Wiper: part number IJ-WIP-02.
• VJ-MS31-CL220E cleaning cartridges (4 Pieces)
• UMS11 or MS31 ink set for XPJ1341SR-Pro
• High capacity ink pack adaptors: 1x VJ-HCIPADPT (1 set contains 4 adaptors)
• New ink pump: part number DH-40598. 

Procedure:

• Start the printer in Board Manager Mode.
• Start MUTOH Service Assistance. Click on Main F/W Update and install the latest available FW version.

• Empty the waste bottle.
• Start the printer in Self-Diagnosis mode.
• Reset the pump life time counter (>parameter>init.counter>pump).
• Go to Check 4:Adjustment > Adj.12:Longstore and perform a "Longstore" using new MS31 cleaning cartridges.
• When the procedure is finished, the panel shows 'Adj. 12: LONGSTORE'.
• Power down the printer.
• Replace the wiper.
• Empty the waste bottle.
• Start the printer in User Mode.
• Display shows: 'INK charge - Start>Enter' , now press <Enter>.
• Insert the MS31 cleaning cartridges (the ones used in the Longstore should contain sufficient cleaning for this second cycle).
• After the washing cycle, the display will show: "Wash Retry?" ==> Choose No.
• Perform an 'ink charge' using UMS11 or MS31 inks (+ the dedicated smart cards)
• Recalibrate the BI-D of the printer.
• End of procedure.

Important INFO:

Incorporated boundaries to use UMS ink on XPJ-1341SR-P

• UMS jetting is implemented for head height ‘Middle’ only.
  Jetting for other head heights is not implemented.
  To avoid operator mistake the machinenvites the operator to put the head height to Middle before it starts printing. The message "Change Head Gap Middle" will be prompted before printing.

This restriction only applies to normal printing in user Mode. Internal pattern printing (user mode) and any printing in Self-Diagnosis Mode will be performed with any head height setting.

• UMS jetting is implemented for the large drop family only (VSD1). VSD1 is used for all printing performed in User Mode and Self-Diagnosis Mode including internal pattern printing. No restrictions applied.
  
  
  

!! Do not forget to perform the Adjustments in Diagnostics mode for “VSD1” and head height “Middle” !!

Notes for Uni/BI Dir adjustment patterns:

• Adjustment pattern for VSD2/VSD3 is also printed with VSD1 (User Mode / Self Diagnosis Mode).
• If the adjustment pattern for PG LOW or HIGH is selected, the head height needs to be set to the selected head height (Self Diagnosis Mode)
