L25500 Printhead Test Plot problem

[SBTFWTX]

Everywhere I look online and in my HP manual says my test plot should look like this.

Had and HP tech come out and look at our printer for other problems that he "fixed". Services performed were Service maintenance kit 3 and replaced our ink supply tubes and trailing cable. Had him take a look at our test plot while he was here.

C/LC and M/LM look just fine

But the Y/K looked bad

HP tech said it looks fine?!?!?! He said the manual is printed wrong. We have had this problem for a while.

Someone have any idea what the problem could be?

Why do you say it looks bad? It looks good to me? All this is is a nozzle test. To see if nozzles have gone out. It has nothing to do with print quality. In fact many printheads can have damaged or nozzles that don't spray and the prints look fine.

Shouldn't it print yellow and black instead of pink and black?

If you think it looks bad because there is a bunch of magenta in the yellow section that is because it was written wrong. if you want I can sendyou the updated service manual for the machine. The health test plot looks identical to yours.

What problem are you talking about?

Your nozzle test looks fine and is the way mine always looked.

The manual is wrong.

If you look there is yellow lines printed. That is all your looking at is the diagonal lines. If there is a step in some of them then you have nozzles out on a printhead of that color. The magenta(not pink) is printed there in a block before the yellow goes down so that you can see the lines better. Something a HP tech thought would be better then trying to read light yellow on a white backer. Watch it print next time it will lay all the magenta down and then go and print yellow over it.

That would be greatly appreciated. Thanks!
