    Hi everyone,
    Wondering if I can get a second opinion on what could be the underlying problem with my Mutoh VJ1604 before I consider replacing the printhead or the printer altogether. Tech has quoted $6,500AUD to replace the printhead.

    Something wrong with the Blue in nozzle it prints with a smudge of blue.
    Seems to only happen with dark blue colours. Pictures attached.
    Nozzle check appears to be missing the 3rd vertical line, right next to the black line.
    I have done short, long and little charge clean with no luck.

    Any feedback would be greatly appreciated.
    Thanks in advance

    First question; How old is that print head?

    If older than 3-4 years, most likely time for a new printhead...also when was the last time you changed your dampers?

    IMHO - If it costs $6500 to replace just the printhead, i would instead get a new printer, with all new parts, bearings, etc.

    The printhead and dampers have never been changed since I got the printer. Previous owner worked from home and I also don't run it much, only couple times a week.
    I've got a mutoh tech coming out to check it out in a couple of days. But it sounds like he wants to test the printing on various settings to improve the print quality rather than repairing any parts.
