Error P-9 not CF2001 not printing Black

[Guest]

Hi:

I'm Having a error p-9 on the LCD Panel of the CF2001.. Black Copies are printing to clear like if Black toner does not have toner. Imaging unit was change a little ago.

Does anybody have a clue about the p-9 error that shows when you click on the OIL IKON in the display

Thanks

I found out after cleaning the black IU the Ikon on the display goes away. But after I print a test Page the Ikon show again.. with the P-9 code..
