Hi, i recently purchased a Sharp electronic type writer model PA-3020 II and its been fine the past few days. I've had no problems typing on it, and today when i went to go and use it, it beeped. every time i press a letter or number it beeps. i read the manual hoping to find something to help me, but nothing referred to my problem. It did say something about left and right margins, but i cant figure out how to use those, even if i do have the manual to guide me through it. i need someone to walk me through how to get this working again, cuz i cant ask a manual questions. thanks, please try to get back to me as soon as you van, bye.
