get the message "Carriage Jam, Clear carriage jam, press OK.  Can't find a jam.  Flashing exclamation mark.  Can't turn off printer. Have followed several instructions to turn on/off, unplug, etc.  Nothing seems to fix it.

Have you physically looked to confirm that there is not something jamming the print carriage. Part of a paper jam, dislodged cartridge? Anything look out of place?

Thanks for your reply.  I have checked everything to the best of "my" ability, and don't see anything out of place.  The printer has shown "shutting down" all night and I can't even turn it off. The start button is flashing.  I checked the print que and there are no pending jobs.  I have unplugged it several times.  I either get the carriage error or the shutting down message.  This started with a paper jam and stopping the job mid way.

The ink cartridge unit does not go all the way to the right (over what looks like a cartridge cleaning area).  A plastic piece stops it from going all the way over.  I don't know if this is the problem.
