We recieve alot of fax information from insurance companies and I can't figure out why some won't come thru. The fax rings says its communicating/receiving then it will ask disregaurd or accept. if we do nothing or hit accept its rings like it is coming thru but then it stops and nothing prints. I have been on the phone with customer support and they tried a few things but still didn't fix problem. Does any one know how to fix this problem?
