yellow colours have an orange bias

[AllanOAP]

My  6950 came with standard set up inks which produced accurate colour reproduction.

I have now installed a complete set of replacement HP inks but the yellow colours in  pictures have an orange bias. The other colours are not as sharp as the originals.

I am printing on a good quality 80g paper

I have done a third level clean - no change.

The printer status report shows 3 perfectly sharp  colours and black.

Sorry that it has taken such a long time to reply.Been away.

Have followed as many suggestions as possible within a limited understanding

Everything seems to print well, pictures are reasonably sharp, but they all have the same problem. There is a bias throughout  toward an orange tone.

I cannot find any way to alter the amount of ink supplied by any one colour

I am using  HP colours and HP papers as have used other quality sheets - no change in results.
