Have printing services to get this done on time. As to the printer you will discover that repair costs should exceed a new printer. If you can't fix it yourself then get ready for new printer or using printer services near you.
I have a Lexmark X4580 Wireless All-in-One Printer/ Copier/Scanner jammed up tight. 3 pieces of 5x7 paper went in & none came out. I can't see paper jam from either end. Troubleshooter says to push check button to clear jam but nothing happens. No response from their tech support I'm in the middle of printing wedding invites. PLEASE HELP!
