This step is optional depending on what shape your printer is in, but since mine was a little older and had been sitting around I decided to clean the print head. This is a pretty easy process since you've now removed the entire assembly and you can just place it on the table while cleaning the head. My print head was pretty dried out and had a lot of old ink stuck on it so I did some research to find out the best way to remove it. What I found to be the best suggestion was to use some cotton swabs to knock some of the larger gunk off before spraying the cotton swab with Windex glass cleaner to really remove the dried out ink from all the surfaces. As you can see from the image I used quite a few cotton swabs to clean the print head really well.
Like I said this step is optional, but it really helped my print head work like new again.
