Hi,  Does anyone know why my My HP Design jet 500ps isn't printing greys and the blacks look green-ish when I do test/calibration prints direct from the printer? Also when I print black and white photos from the computer they come out with a blue-ish tint. (I have made sure the print settings are on greyscale).

 

I have attached photos of the test/calibration prints direct from the printer along with a stock photo of a dog that I tried to print where the grey background came out blue-ish purple. 

 

I have replaced the blue and black print heads to see if that was the problem but it didn't work.

 

Thanks, 

 

Martin.

From the photos, it looks like you have some poor performing printheads.  I'd start there.

I don't work for HP....I just repair their printers.
