Problem with printing gradient text using Docucolor 252

Hello everyone!
I've been trying to print a flyer that has a gold/yellow gradient text.
The problem is that the text with the applied gradient does not print as smooth as
the rest of the solid colored text. It is kinda rough all around.

I use illustrator cs4 and the text has to be "expanded" to apply a gradient.
When I saw it doesn't work, I tried to make a clipping mask using plain text with the gradient
as the background of the mask. Still the same..
I even used Photoshop to create the text and export it to png transparent with 1000dpi..!
and still the nothing.

Does anyone have a solution or encoutered the same issue?
Thank you in advance

 

Hi,
enter diagnostic and do max setup then adjust high light seting and exit then calibrate scaner and printer
repeat so when have a good gradient print
