Hey guys, Hoping you can help me with this. I am going to be going to a customer's house after work today so I can troubleshoot her HP PSC All-in-one Fax, Printer, copier, scanner device, as to why it will not send faxes out. They say that they have tried everything and cannot get the fax portion of it to work. They have DSL and filters and everything, but they still aren't able to get it to respond. What should I be looking for when I am going to this customer's house? I don't know too much about DSL when it regards filters, so would that possibly be interfering with the operation of the fax machine? Hopefully someone can shed some light on this issue. Thanks!
