My Pro 100 won't print yellow

[claudale]

Any suggestions?

I noticed my prints looked bad and I noticed that I hadn't filled the yellow in a while.  I ran test pages and that was the only color not printing.  

I figured the ink was old and I put in a brand new yellow ink and it still doesn't print.  I tried deep cleaning and the printer doesn't think anything is wrong.  Also if I touch the tip of the yellow ink on a napkin, yellow ink does come out.

thanks

Did you not use your printer for a long while.  Like a month or so?  If you have been using it regularly, say even once a week, it isn't a clogged print heard.  Most likely, I mean as anything is possibile.  The best practice is to print something at least once a week or two.

When you manually try to clean the print head be careful as there are gold contacts and electronic contacts there.

Thanks to both of you, it's now working
