I have 4 okidata microline printers that have come in from stores to be put on the shelf for future use. These came in from either warehouse environments or counter sales where they sat humming along for years with no one doing anything to them but change the paper.
I've done a light wipe down but I want to take them apart an d to a serious cleaning. What is the best cleaning solution to use to really get the dirt off the plastic. (these things are filthy)
I want to clean all the print heads as well, and one needs a new set of tractors,
Suggestions?
