Greetings,
The key is keeping the dust out in the first place. I have a nylon type cover for every printer I own. I order them from Amazon - Comp Bind is the brand. I keep everything covered when not in use. My HP officejet is almost 9 yrs old and its in pristine condition. The Pixma 100 and 644Cdw are also covered.
Getting dust off the underside of the platen glass is difficult. Canned air. Wear rubber or latex gloves. You might have to disassemble, but be careful as alignment issues can result. I don't think there is a "safe" way of doing it.
Again, avoiding dust in the first place is the best bet. Seems to be something we all have to deal with.
