Hello, my name is ***** ***** I can help you with your question.
To get rid of those 600 pending pages, you have to RESET the Fax Setting on your unit (while keeping the tray open to prevent any further printing).
- If that fails you might have to RESET the whole unit in General. Usually faxes once they start printing they locate themselves on Memory in the RECEIVING end and not the Sender.
Try that and let me know if I could of further help.
