Product: HP DesignJet T120
Operating System: Microsoft Windows 10 (64-bit)

After leaving my T120 turned off too long, I have been able to revive the printhead about 90%.  I have run the 3 levels of printhead cleaning 6 times.   I have taken out the cartridge carriage several times and wiped with a damp lint-free cloth between running the printer based 3 level cleans.  Now, all colors are printing well except about 30% of the blue at one end of the test print blocks.   Any advice on the best method to clean the printhead and how to the finish getting the printhead to work 100%.  Any advice appreciated!

In case anyone is interested, I soaked to printhead in a shallow pool of water (about 1/8" deep) for about 5 minutes.  After running the 3 level print head cleaning another 3 cycles, the printhead is working quite well.  

 

This avoided spending over $200 for a new printhead as HP suggests in the printer's message after running 1 set of 3 level cleaning.  Nice, eh?

 

I am sure many people have asked this same question, but I could not find any posts related well enough to this topic with the search capability of this forum.  If I am missing a trick to searching, please show me a post where I could have found a solution.  

 

Thanks!
