    Brother MFC-L3770CDW print quality issues

    I have a brother colour laser printer with about 30% drum life remaining but the print quality is really poor.
    I have tried cleaning the LEDs and running calibration/registration but it hasn't improved.
    Any idea what else to try?
    Here is a scan of a test print, as you can see there are lines, some black in the yellow and the black is not very black.

    Brother tech will know.
    A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

    Blessed are they who can laugh at themselves, for they shall never cease to be amused.

    Sorry I should have included more information.
    Drum - all genuine with 36% life remaining
    Belt - 82% life remaining
    Fuser - 77% life remaining
    Toner - non genuine
    Page counter - 11673
    Paper is stored in dry environment and works fine in another laser printer we have.

    Change the Drum. We have found that non genuine toners destroy the drum quicker.

    I have found with equipment that low page count per job will also shorten the life of drums.

    True that it's in the specs, ie 30k pages(1 page job) or 50k pages life at 3 pages jobs.

    I never print any legal sized docs, all a4.
    Mostly just office documents with charts and images etc
    OEM drums, compatible toners.
    Drums have never been replaced, they are the originals.
    Printer is about 2 years old.

    Total Pages Printed
    Total 11673 Page(s)
    Colour 8732
    B&W 2941



    Sounds like I need new drums.

    The 18,000 expected drum life is for using Genuine Brother toner. Time for a new set of drums.
