Attempts to print from the paper tray on my Dell 1700 printer always results in the "Paper Jam" indicator illuminated. No paper jam ever exists. However, the paper begins to feed from the paper tray but the print cycle stops there. I've used the quick double click on the "Continue" button to find the secondary error code, this results in the "Continue", "Ready/Data" and "Paper Jam" indicators illuminated which indicates a "Paper Jam at the Input Sensor" with directions to see Printer Solution ID: 413611. I have accessed this document but it does not tell how to fix the problem or how to repair the printer. One other piece of information, the print process works properly if I feed single sheets through the manual feed mechanism. Any help would be greatly appreciated.
