Hi

I have a Brother MFC-L8390CDW laser printer.
Recently the quality has deteriorated - vertical streaks - see attached Print Test.
The printer toner life shows all at around maybe 15%?
Is it just that the toners need replacing or is something else potentially happening?
The print tally is 3,915 pages. They are generic toner cartridges.

I've cleaned the corona wires by sliding the green tab across multiple times.
I rocked the cartridges side to side several times prior to reinstalling.
No change to the print quality.


Appreciate any advice.
Thank you.
Wilkie
