Head clogs are a pain and expensive if you have to do a lot of flushing and it is only one color that is giving you problems. If you have heads built into the cartridge you can some times get away with pulling the cartridge out and soaking the head in a saucer or bowl of shallow warm water. If you don't, you will most likely use warm water on a folded paper towel, fold it, lay it in the path of the print head and move the head over it and let it sit for an hour to over night. Some folks, my self included get antsy and use windex instead of water. Then you power clean the heads. That can use an awfull lot of ink in a LF printer, especially if you have to do it several times.

So scouting around, I found this http://www.marruttusa.com/printer-maintenance/inkjet-printer-purge-files.php

They have some interesting print outs for separate colors, and combos. I use the combo once a week on my 9600's and have not had to worry about the heads getting partial clogs when the printers are inactive for a while. If I find a head that has some clogging, I fill the capping station with warm water, let it sit for a short time, and print the corresponding color for the clog or clogs. Some times the head will not appear to be clogged, but the color will be off, and this will correct it.

I would also recommend doing this before profiling a paper. Have one printer that I was having a hard time getting the Colormunki to read one of the columns. Printed out the combo sheet, reran the CM sheet and checked it against the first one and it became obvious as to why it would not read the profile.

Works extremely will for me, so maybe something to check out. Hope it helps someone, it has saved me an awful lot of ink, strain on my printers and my sanity.
