How to trouble shoot printer error?

Computer: Dell Inspiron 580s

OS: Windows 7 64-bit

Printer: Dell 1320c

Problem: Cannot print. When I attempt to print the printer flashes an error light. The paper is not pulled. The printer was working fine up until this week.

Troubleshooting attempted:

1. Checking for paper jams (clear)
2. Changing toner
3. Power reset (turn off, unplug, plugin, turn on) This results in no error light. When I attempt to print, error light comes back.
4. Uninstall and reinstall of printer drivers.
5. Reviewed print queue. When I attempt to print, it sends the job to printer, gets to 100 of 300 sent, but then hangs on "sent to printer".

Thank you for your help.
