Please remove the cartridge and wipe the nozzle gently with a tissue. Then flush out the sprayer by pressing the nozzle button (you should feel air coming out of the nozzle head). Insert a cartridge into the nozzle and listen for a "click". Spray in a circular fashion about one inch away from the paper.
