[CQ] Brother MFC-L3770CDW print quality issues

[s10]

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.

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.

do you print many legal sized docs?
what do you print?
total page counts?
OEM drums n toners?
when was the last time the drums were replaced?

so many questions so little info.

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

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.

and some OEM toners. don't ruin the new drums by still using the junk toners in the copier.
