Carriage jamed.... I have a HP Officejet Pro L7580, I had a paper jam and as far as I can tell I thought I got it all out. but it keeps giving me a Carriage Jam message now and I'm lost on were else to look or what else to do.

Good ! that u have mentioned the name of ur printer
paper jam error message appers whenever the pick rollers that helps in pulling the papers are dirty but you will not be able to clean those rollers as you may tru to do a power drain :
1:disconnect the power cable from the back of the printer
2:hit the power button for 10 times when the power cable is disconnected
3:reconnect the power cable and try to see the error again
4: try to clean the rollers on the printer that is there at the back of the printer and front of the printer with a cotton cloth or a lint free cloth with some water

this is for paper jam

carriage jam:
1: try to move the carriage manually for 10 to 15 times and if that is moving then its ok otherwise your printer funtionality has gone bad as because if the carriage will not move then you will not able to print
so service your product
