clean your OLIVETTI PR4 ribbon cartridge step

let’s go over how you should clean your OLIVETTI PR4 ribbon cartridge step by step:
In order to clean the print head, you’re going to need a bottle of rubbing alcohol. Make sure the rubbing alcohol is 70 percent by volume and that it is isopropyl rubbing alcohol. To apply the rubbing alcohol to the print head, you’ll want to use either q-tips or a lint-free rag.
Moisten the lint-free rag or the q-tip with rubbing alcohol. Wipe either the moistened rag or q-tip over the thermal print head a couple of times, using only a small amount of pressure. This will allow you to remove the olivetti printer ribbons dust and the carbon buildup and tends to collect over time.
