I just got an HP 8730 printer to replace a HP 8630 which was a great, never had a paper jam. The new 8730 jams all the time when printing. When HP changed the paper output tray they made the paper sensor to sensitive. The HP fix is keep removing the papers. I just returned this printer and will be getting the same one. I hope it was just a defect in the machine I returned. The printer does have a lot of good features. Does anyone else have a paper jam problem when printing a lot of papers and a solution?
