Software to exercise individual inkjet nozzles

Is there anything out there that does this for an epson R2400.
I need to push some ink thru one erratic nozzle & am tired of blowing a lot of ink through nozzles that work fine. (My light black, position 5 from the right.

thanks, robert

Thanks Don, that is a very useful utility. It's also going to help me to essentially turn off the color cartridges on this machine that I'm doing black-only on.

I got my R2400 going that was put away for 2 years with cartridges in. I used a syringe to saturate the head parking sponges with distilled water and left it untouched for 1 1/2 days. Took a 3 cleanings with a new set of cart's but the nozzle checks come out perfect now.
