Printer quality question

Hi everyone!

I just got a hand me down Brother 9320cw color laster multi-function printer. The quality of print seems off. Attached is a picture of a print I did. The green should be solid but its coming out gradient. Any ideas what it needs?

Thank you in advance!

 

To me it looks like the cyan drum may be failing. The first thing I do when there is a quality issue is to print a sheet which has blocks of pure cyan, magenta, yellow, and black running side to side on the sheet. Then you can see if the defect is caused by one color.
