grays printing pinkish

All of a sudden my HP315 is printing grays with a pink tint. Looking at the files and even though there is no magenta in any of the colors, they still look pink. WTH?!?

Any idea how to remedy this?


Problem Solver
If you are 100% sure your file is okay and you havent changed anything in RIP then.

Have you done color calibration?
If you have and it didn't help you may have a printhead going bad.
That's about all the most likely reasons.
include the possibility of a corrupt profile

try a grey with different profile see if it is ok

if still same result then check profiles on both
rip and printer itself.....

Could be Printer Linerization if it is doing it in all your greys and not just that one file. I had that happen to my Roland several years and had to have my printer and profiles calibrated
