Microboards Print Factory II CD feeder problem

Hi, since first time we bought the machine, the feeder did not support 100 CDs, even we put first 10 flat and make rest 90 CDs with an angle. We normally put 10 CDs in it it worked fine. Now the problem is new, the feeder has motor noise when feed CDs, it is very loud and sometimes fed 2 CDs at a time and got jam. Must be something wrong with the feeder? Please let me know asap if we need to send it back to get it repaired. Thanks. Flexpress Ltd. www.flexpress.co.uk Leicester
