NOTE: I referred to these posts for guidance on troubleshooting this issue:
Two things listed to try, either by themselves or in conjunction with each other are:
1) Turn the ePrint Service off then on again (weird I know, but remember the most common fix for MS Windows computers is to restart the machine) and
2) Use manual DNS addresses as 18.104.22.168 and 22.214.171.124 for Preferred and Alternate DNS’s, respectively.
I tried both of these and there was no change in my issue. The isssue, BTW, for me personally is that I have apparently successfully registered with the eFax service via my printer (HP Photosmart 7510 e-All-in-One Printer – C311), but it always hangs when “Sending eFax“. The it returns the message:
Also … do you have to prefix a 1 in the USA to send a fax? Maybe that’s the issue??
UPDATE: Nope, tried prefix with a 1 and that didn’t help either. Same error.
3) I also registered my HP ePrint mobile printing at eprintcenter.com. ePrintCenter says “connected” and “ready“. Tried refreshing the printer then retried faxing again, only to receive the same error noted above.
I don’t know what else I can do with this as I have investigated various blog posts for a good answer, … unfortunately none of the answers provided helped my situation. If anyone has any knowledge of this issue I’d love to hear what your experiences have been … just post your responses below. Any help is appreciated because I’m stumped on this one friends!
