Query: I'm on second replacement

I can't receive any message from this fax and make a copy because of paper jam. when trying to copy a documents the sheets goes in OK but the printing paper gets jammed. this is my second replacement for this problem. but,my second replacement has also this problem. I asked this problem to Sharp custmer center because the dealer doesn't exchange to new one any more because of 45days waranty period. I used this model 2 times to receive a fax since I exchanged to new one. I don't want this model any more. I'm waiting for the staff's opinion of Sharp for this problem.
