Problems with oki c9500

[serbring]

Hi all,

I have an oki c9500, it worked very well for long time, but lately it prints bad. In attachement you can see one print sample.
As you can see there are few coloured stripes and the magenta is a bit out of phase and therefore colored pages are difficult to read.

What could I do to fix the problem?

Thanks


Cheers
