I had a paper jam in the duplex setting, followed the well-depicted instructions on the Zeen, cleared it and went on to continue my printing. But nothing would print. Solution Center said "Documant failed to print. [BIG surprise} Clicked & got a message that said, " The job failed to print due to an error in the printing system." Went thru e^ery step in the Solution Center & nothing helped. Tried the toolbox but I could not print out a diagnostic test sheet. Tried a few other suggestions in the handy help section but no success.
So I re^erted to the old tried & true, if all fails.... I shut down the printer & started it up again. Got two sets of diagnostic self-tests, extended, no less. Working perfectly now. (Solution center did suggest shutting my computer down, but I ha^e about six processes open in ^arious stages of my doing something, so I did not like that solution. ( I also lost the ^ on my keyboard today....)
